Patent Application
20180285824
The subject matter disclosed herein generally relates to methods, systems, and programs for finding quality job offerings for a member of a social network.
Some social networks provide job postings to their members. The member may perform a job search by entering a job search query, or the social network may suggest jobs that may be of interest to the member. However, current job search methods may miss valuable opportunities for a member because the job search engine limits the search to specific parameters. For example, the job search engine may look for matches in the job title with the member's title, but there may be quality jobs that are associated with a different title that would be of interest to the member.
Further, existing job search methods may focus only on the job description or the member's profile, without considering the member's preferences for job searches that go beyond the job description or other information that may help find the best job postings for the member.
Various ones of the appended drawings merely illustrate example embodiments of the present disclosure and cannot be considered as limiting its scope.
Example methods, systems, and computer programs are directed to grouping job postings for presentation to a user in response to a search. Examples merely typify possible variations. Unless explicitly stated otherwise, components and functions are optional and may be combined or subdivided, and operations may vary in sequence or be combined or subdivided. In the following description, for purposes of explanation, numerous specific details are set forth to provide a thorough understanding of example embodiments. It will be evident to one skilled in the art, however, that the present subject matter may be practiced without these specific details.
One of the goals of the present embodiments is to personalize and redefine how job postings are searched and presented to job seekers. Another goal is to explain better why particular candidate jobs are recommended to the job seekers. The presented embodiments provide, to both active and passive job seekers, valuable job recommendation insights, thereby greatly improving their ability to find and assess jobs that meet their needs.
Instead of providing a single job recommendation list for a member, embodiments presented herein define a plurality of groups, and the job recommendations are presented within the groups. Each group provides an indication of a feature that is important to the member for selecting jobs for the group, such as how many people have transitioned from the university of the member to the company of the job, who would be a virtual team for the member if the member joined the company, jobs that are trending, and so forth. Thus, the embodiments are able to provide insight into the methods of job selection to the user by providing groups of jobs, with all jobs in the group sharing one or more features. Thus, the user is given insight into why certain jobs are presented within a particular group.
Embodiments presented herein determine jobs that are popular among proxy members, which have similar skills to the searching member, by tracking the interactions of the proxy members with the jobs. Thus, a value can be presented to a member of how the jobs are trending among proxy members. In some embodiments, one or more companies that are offering the trending jobs are presented to the user. In this way, a system can analyze data to compare proxy members with a searching member and determine a job-interaction score for a job based on the similarity between the searching member and the proxy members as well as the interactions by the proxy members with the job.
One general aspect includes a method for determining a first skill set for the searching member on a social network, the first skill set including at least one skill from the user profile. The method also includes operations for identifying jobs listings that are offered by companies. The method also includes operations for identifying one or more proxy members having skills similar to the skills of the searching member. The method also includes operations for calculating a job-interaction score based on a level of interaction between the proxy members and the job. The method also includes operations for ranking the jobs based on the job-interaction scores and for presenting the jobs within a trending-jobs group area in an order based on the ranking.
In some embodiments the first skill set includes one or more skills that are calculated using a machine learning tool, and the calculations are based on a similarity score that measures a similarity between the first skill set and a second skill set of a second member. In some embodiments, the level of interaction between the plurality of members and the job is based on an aggregation of member interactions, the member interactions being instances of a proxy member applying for the job, viewing the job, or sharing the job. Further, in some embodiments, the job-interaction score is further based on a value of member interactions by proxy members being met, by proxy members being employed at the company offering the job, or by proxy members sharing a common location with the searching member. In some embodiments, the job-interaction score is based on a job affinity score, the job affinity score being a measure of a degree of matching attributes between attributes of the first member and attributes of the job. In some embodiments, the method further includes calculating a company trend score based on the job interaction scores of jobs offered by the company, ranking the companies based on company trend score, and causing presentation of the companies in a user interface based on the ranking.
Consistent with some embodiments, when a person initially registers to become a member of the social networking server 120, the person will be prompted to provide some personal information, such as his or her name, age (e.g., birth date), gender, interests, contact information, home town, address, spouse's and/or family members' names, educational background (e.g., schools, majors, etc.), current job title, job description, industry, employment history, skills, professional organizations, interests, and so on. This information is stored, for example, as member attributes in the member database 132.
Additionally, the data layer 103 includes a job database 128 for storing job data. The job data includes information collected from a company offering a job, including experience required, location, duties, pay, and other information. This information is stored, for example, as job attributes in the job database 128.
Additionally, the data layer 103 includes a similarity database 134 for storing data related to calculating a similarity between members. The data layer 130 additionally includes company data, such as company name, industry associated with the company, number of employees at the company, address of the company, overview description of the company, and job postings associated with the company. Additionally, the company data includes a benefit value that measures benefits experienced by employees that work for the company. The benefit value may be determined by assessing various features, including the provision of company meals, rate of promotion within the company, vacation time, and starting salary.
Once registered, a member may invite other members, or be invited by other members, to connect via the social networking server 120. A “connection” may specify a bilateral agreement by the members, such that both members acknowledge the establishment of the connection. Similarly, in some embodiments, a member may elect to “follow” another member. In contrast to establishing a connection, the concept of “following” another member typically is a unilateral operation, and at least in some embodiments, does not prompt acknowledgement or approval by the member who is being followed. When one member connects with or follows another member, the member who is connected to or following the other member may receive messages or updates (e.g., content items) in his or her personalized content stream about various activities undertaken by the other member. More specifically, the messages or updates presented in the content stream may be authored and/or published or shared by the other member, or may be automatically generated based on some activity or event involving the other member. In addition to following another member, a member may elect to follow a company, a topic, a conversation, a web page, or some other entity or object, which may or may not be included in the social graph maintained by the social networking server 120. In some example embodiments, because the content selection algorithm selects content relating to or associated with the particular entities that a member is connected with or is following, as a member connects with and/or follows other entities, the universe of available content items for presentation to the member in his or her content stream increases.
Additionally, the data layer 103 includes a group database 130 for storing group data. The group database 130 includes information about groups (e.g., clusters) of jobs that have job attributes in common with each other. The group data includes various group features comprising a characteristic for the group, as discussed in more detail below. This information is stored, for example, as job attributes in the job database 128.
As members interact with various applications, content, and user interfaces of the social networking server 120, information relating to the member's activity and behavior may be stored in a database, such as the member database 132 and the job database 128.
The social networking server 120 may provide a broad range of other applications and services that allow members the opportunity to share and receive information, often customized to the interests of the member. In some embodiments, members of the social networking server 120 may be able to self-organize into groups, or interest groups, around a subject matter or a topic of interest. In some embodiments, members may subscribe to or join groups affiliated with one or more companies. For instance, in some embodiments, members of the social networking server 120 may indicate an affiliation with a company at which they are employed, such that news and events pertaining to the company are automatically communicated to the members in their personalized activity or content streams. In some embodiments, members may be allowed to subscribe to receive information concerning companies other than the company with which they are employed. Membership in a group, a subscription or following relationship with a company or group, and an employment relationship with a company are all examples of different types of relationships that may exist between different entities, as defined by the social graph and modeled with social graph data of the member database 132.
The application logic layer 102 includes various application server modules 124, which, in conjunction with a user interface module 122, generate various user interfaces with data retrieved from various data sources or data services in the data layer 103. In some embodiments, individual application server modules 124 are used to implement the functionality associated with various applications, services, and features of the social networking server 120. For instance, a messaging application, such as an email application, an instant messaging application, or some hybrid or variation of the two, may be implemented with one or more application server modules 124. A photo sharing application may be implemented with one or more application server modules 124. Similarly, a search engine enabling users to search for and browse member profiles may be implemented with one or more application server modules 124. Of course, other applications and services may be separately embodied in their own application server modules 124. As illustrated in
In another example embodiment, a job search interface is provided for entering job searches, and the resulting job matches are presented to the user in the user interface 200.
As the user scrolls down the user interface 200, more job recommendations are presented to the user. In some example embodiments, the job recommendations are prioritized to present jobs in an estimated order of interest to the user.
The user interface 200 presents a “flat” list of job recommendations as a single list. Other embodiments presented below utilize a “segmented” list of job recommendations where each segment is a group that is associated with a related reason indicating why these jobs are being recommended within the group.
In one example embodiment, the member profile 302 may include information in several categories, such as a profile picture 304, experience 308, education 310, skills and endorsements 312, accomplishments 314, contact information 334, following 316, and the like. Skills include professional competences that the member has, and the skills may be added by the member or by other members of the social network. Example skills include C++, Java, Object Programming, Data Mining, Machine Learning, Data Scientist, and the like. Other members of the social network may endorse one or more of the skills and, in some example embodiments, the member's account may be associated with the number of endorsements received for each skill from other members.
The experience 308 information includes information related to the professional experience of the user. In one example embodiment, the experience 308 information includes an industry 306, which identifies the industry in which the user works. In one example embodiment, the user is given an option to select an industry 306 from a plurality of industries when entering this value in the member profile 302. The experience 308 information area may also include information about the current job and previous jobs held by the user.
The education 310 information includes information about the educational background of the user, including the educational institutions attended by the user, the degrees obtained, and the field of study of the degrees. For example, a member may list that the member attended the University of Michigan and obtained a graduate degree in computer science. For simplicity of description, the embodiments presented herein are presented with reference to universities as the educational institutions, but the same principles may be applied to other types of educational institutions, such as high schools, trade schools, professional training schools, and the like.
The skills and endorsements 312 information includes information about professional skills that the user has identified as having been acquired by the user and endorsements entered by other users of the social network supporting the skills of the user. The accomplishments 314 area includes accomplishments entered by the user, and the contact information 334 includes contact information for the user, such as an email address and phone number. The following 316 area includes the names of entities in the social network being followed by the user.
The skills within the skills and endorsements 312 information are aggregated by the system to form a skill set for the user that can be compared to other users. In some embodiments, this skill set is part of a member characteristic for the user, the member characteristic including information such as the skill set for the user, profile information, education 310 information, and other data that is further comparable to other members.
The search section 404, in some example embodiments, includes two boxes for entering search parameters: a keyword input box for entering any type of keywords for the search (e.g., job title, company name, job description, skill, etc.), and a geographic area input box for entering a geographic area for the search (e.g., New York). This allows members to execute searches based on keyword and location. In some embodiments, the geographic area input box includes one or more of city, state, ZIP code, or any combination thereof.
In some example embodiments, the search boxes may be prefilled with the user's title and location if no search has been entered yet. Clicking the search button causes the search of jobs based on the keyword inputs and location. It is to be noted that the inputs are optional, and only one search input may be entered at a time, or both search boxes maybe filled in.
The daily jobs section 406 includes information about one or more jobs selected for the user, based on one or more parameters, such as member profile data, search history, job match to the member, recentness of the job, whether the user is following the job, and so forth.
Each group area 408 includes one or more jobs 202 for presentation in the user interface 402. In one example embodiment, the group area 408 includes one to six jobs 202 with an option to scroll the group area 408 to present additional jobs 202, if available.
Each group area 408 provides an indication of why the member is being presented with those jobs 202, which identifies the characteristic of the group. There could be several types of reasons related to the connection of the user to the job, the affinity of the member to the group, the desirability of the job, or the time deadline of the job (e.g., urgency). The reasons related to the connection of the user to the job may include relationships between the job and the social connections of the member (e.g., “Your connections can refer you to this set of jobs”), a quality of a fit between the job and the user characteristics (e.g., “This is a job from a company that hires from your school”), a quality of a match between the member's talent and the job (e.g., “You would be in the top 90% of all applicants), and so forth.
Further, the group characteristics may be implicit (e.g., “These jobs are recommended based on your browsing history”) or explicit (e.g., “These are jobs from companies you followed”). The desirability reasons may include popularity of the job in the member's area (e.g., most-viewed by other members or most applications received), jobs from in-demand start-ups in the member's area, and popularity of the job among people with the same title as the member. Further yet, the time-urgency reasons may include “Be the first to apply to these jobs,” or “These jobs will be expiring soon.”
It is to be noted that the embodiments illustrated in
In some example embodiments, the information about the job includes the title of the job, the company offering the job, interactions of other members with the job (number of views, number of applicants), the location of the job, and other members in the searching member's 160 social network who are currently formally employed by the company offering the job.
In one example embodiment, the group area 408 includes profile pictures 504, within the recommendations of jobs 202, of proxy members that have recently interacted with the job 202. Additionally, each job 202 includes a job-interaction score display 506 representing the level of interaction between the proxy members and the job 202.
The job affinity score 606, between a job 202 and a member profile 302, is a value that measures how well the job 202 matches the interest of the member profile 302 in finding the job 202. A so-called “dream job” for a member would be the perfect job for the member and would have a high, or even maximum, value, while a job that the member is not interested in at all (e.g., in a different professional industry) would have a low job affinity score 606. In some example embodiments, the job affinity score 606 is a value between zero and one, or a value between zero and 100, although other ranges are possible.
In some example embodiments, a machine-learning program is used to calculate the job affinity scores 606 for the jobs 202 available to the member. The machine-learning program is trained with existing data in the social network, and the machine-learning program is then used to evaluate jobs 202 based on the features used by the machine-learning program. In some example embodiments, the features include any combination of job data (e.g., job title, job description, company, geographic location, etc.), member profile data, member search history, employment of social connections of the member, job popularity in the social network, number of days the job has been posted, company reputation, company size, company age, profit vs. nonprofit company, and pay scale. More details are provided below with reference to
The group affinity score 710 indicates how relevant the group 712 is to the member, where a high affinity score indicates that the group 712 is very relevant to the member and should be presented in the user interface, while a low affinity score indicates that the group 712 is not relevant to the member and may be omitted from presentation in the user interface.
The group affinity score 710 is used, in some example embodiments, to determine which groups 712 are presented in the user interface, as discussed above, and the group affinity score 710 is also used to order the groups 712 when presenting them in the user interface, such that the groups 712 may be presented in the order of their respective group affinity scores 710. It is to be noted that if there is not enough “liquidity” of jobs for a group 712 (e.g., there are not enough jobs for presentation in the group 712), the group 712 may be omitted from the user interface or presented with lower priority, even if the group affinity score 710 is high.
In some example embodiments, a machine-learning program is utilized for calculating the group affinity score 710. The machine-learning program is trained with member data, including interactions of users with the different groups 712. The data for the particular member is then utilized by the machine-learning program to determine the group affinity score 710 for the member with respect to a particular group 712. The features utilized by the machine-learning program include the history of interaction of the member with jobs from the group 712, click data for the member (e.g., a click rate based on how many times the member has interacted with the group 712), member interactions with other members who have a relationship to the group 712, and the like. For example, one feature may include an attribute that indicates whether the member is a student. If the member is a student, features such as social connections or education-related attributes will be important to determine which groups are of interest to the student. On the other hand, a member who has been out of school for 20 years or more may not be as interested in education-related features.
Another feature of interest to determine group participation is whether a job listing is trending amongst members that are similar to the searching member 160. As used herein, a job listing is considered to be “trending” when there is a high level of member activity (such as job applications, shares, and clicks) associated with the job listing compared to other job listings. The trending jobs will be more interesting to the searching member when other members, with skills similar to the skills of the searching member 160, are showing interest in these trending jobs. A benefit to presenting jobs of interest to similar members (as demonstrated via click data, page views, applications, etc.) is that the job listing's popularity stems from a unique fit of the similar members (and thus, potentially, the member) to the job. Also, trending jobs may be more popular among similar members due to better benefits offered by the company hiring for the job (such as better pay, quicker rate of promotion, etc.).
The job-to-group score 708 between a job 202 and a group 712 indicates the job 202's strength within the context of the group 712, where a high job-to-group score 708 indicates that the job 202 is a good candidate for presentation within the group 712 and a low job-to-group score 708 indicates that the job 202 is not a good candidate for presentation within the group 712. In some example embodiments, a predetermined threshold is identified, wherein jobs 202 with a job-to-group score 708 equal to or above the predetermined threshold are included in the group 712, and jobs 202 with a job-to-group score 708 below the predetermined threshold are not included in the group 712.
In the trending-jobs group, the job-to-group score 708 of a job is referred to as the job-interaction score which measures a level of interaction between the proxy members and the job 202. The job-to-group score 708 provides an indication of how important it is to present the job to the user within the trending-jobs group area 408. This is useful because an overall trend of similar people applying to a job, viewing the job, or accepting employment at the company may indicate that the job is a good employment opportunity for the searching member 160.
In some example embodiments, the interactions considered for calculating the Joe-interaction score are those occurring within a predetermined period of time, such as interactions taking place within the last month. In some example embodiments, the system may further apply a dampening effect based on the age of the interactions for calculating the job-interaction score display 506, whereby the most recent interactions are weighted with a higher value than older interactions.
In some embodiments, companies that are offering jobs that proxy members to the searching member 160 are interacting with may provide better employment opportunities for the searching member 160 than other companies. For example, the system may determine a high score for a first job based on a high surge in applications by proxy members for the first job in the past year, as well as by the fact that a high number of proxy members are also applying to jobs offered by the same company offering the first job.
In some example embodiments, the job affinity score 606, the job-to-group score 708, and the group affinity score 710 are combined to obtain a combined affinity score 714 for the job 202. The scores may be combined utilizing addition, weighted averaging, or other mathematical operations.
In some example embodiments, the interactions between members and jobs on the social network are not taken into consideration after a predetermined period of time. In an example, a member view of a job is considered a member-job-interaction if it occurred within the last 12 days, although other periods of time are also possible. In another example, a member application to a job is considered a member-job-interaction if it occurred within the last 20 days, but other time thresholds are also possible, such as in the range between 3 and 180 days.
Also depicted in
Member-job-interactions 804 are interactions (e.g., views, applications, shares) between the subset of proxy members 904 and the plurality of jobs 806. In some example embodiments, member-job-interactions 906 that occur between proxy members and jobs define a subset 912 of jobs.
In some example embodiments, for each job within the subset 912, the system determines the job-interaction score. In some example embodiments, the job-interaction scores are based on the proxy-job-interactions between the jobs and the subset of proxy members 904 as well as the skill comparisons between the searching member 160 and the proxy members. For example, the job-interaction score IS(J) for a job J may be calculated with the following equation:
Within this formula, CN is a coefficient, that the system accesses from the group database 130, based on the number of proxy members used for determining the job-interaction score IS(J). SCi is the similarity score from comparing skills of the searching member with the skills of member i (e.g., skill comparison A for member A as shown on
In an example illustrated in
In some example embodiments, the system uses different equations to determine the job-interaction score. In an example, the system uses a dampening formula on interaction variables NVi(J), NAi(J), and NSi(J) based on how recently the interactions occurred. For example, if a first proxy member has viewed a first job 10 times within the past two days, this suggests a stronger trend than the same proxy member viewing a second job 10 times, but the views all occurred more than five days ago. The system can use the dampening formula to increase the value of interaction variables representing more recent interactions, such as the first job in the example. In some example embodiments, the system uses other equations to calculate the job-interaction score, including equations that make use of other statistical values such as, averages, geometric averages, logarithmic functions, algorithms, etc.
In some example embodiments, the system accesses a threshold interaction value for the jobs and calculates the job-interaction score if the threshold interaction value is met. For example, a threshold interaction value may be that the job has been viewed 18 times by at least two proxy members in the last 10 days. If the job fails to meet this threshold, the system assigns a zero job-interaction score to the job and the job is not displayed in the interaction group area.
In some example embodiments, data about the current job of a first proxy member is further used to calculate the job-interaction score between the first proxy member and a first job. For example, if the first proxy member currently holds a position that has the same job title as the first job, then the job-interaction score would be higher than if the job titles were different. Further, the first proxy member currently holding a position that the system determines (by use of machine-learning) to have a high transfer rate to the position of the first job would similarly result in a higher job-interaction score than if the first proxy member held a position that had a low transfer rate.
In some example embodiments, the location of the proxy member compared to the searching member 160 is used to calculate the job-interaction score between the proxy member and a job. For example, the searching member 160 and the proxy member living in the same city would result in a higher job-interaction score than if the searching member 160 and the proxy member lived in different cities, since it is probable that members in the same location will be interested in similar jobs.
In some example embodiments, the system utilizes the jobs that have been assigned job-interaction scores to determine a company trend score for each company based on the jobs offered by each company. In an example, the company trend score for a company is based both on number of job-interaction scores from proxy jobs offered by the company and their job-interaction scores.
Machine learning is a field of study that gives computers the ability to learn without being explicitly programmed. Machine learning explores the study and construction of algorithms, also referred to herein as tools, that may learn from existing data and make predictions about new data. Such machine-learning tools operate by building a model from example training data 1012 in order to make data-driven predictions or decisions expressed as outputs or assessments (e.g., a score) 1020. Although example embodiments are presented with respect to a few machine-learning tools, the principles presented herein may be applied to other machine-learning tools.
In some example embodiments, different machine-learning tools may be used. For example, Logistic Regression (LR), Naive-Bayes, Random Forest (RF), neural networks (NN), matrix factorization, and Support Vector Machines (SVM) tools may be used for classifying or scoring job postings.
In general, there are two types of problems in machine learning: classification problems and regression problems. Classification problems aim at classifying items into one of several categories (for example, is this object an apple or an orange?). Regression algorithms aim at quantifying some items (for example, by providing a value that is a real number). In some embodiments, example machine-learning algorithms provide a job affinity score 606 (e.g., a number from 1 to 100) to qualify each job as a match for the user (e.g., calculating the job affinity score 606). In other example embodiments, machine learning is also utilized to calculate the group affinity score 610 and the job-to-group score 608. The machine-learning algorithms utilize the training data 1012 to find correlations among identified features 1002 that affect the outcome.
In one example embodiment, the features 1002 may be of different types and may include one or more of member features 1004, job features 1006, interaction features 1008, and other features 1010. The member features 1004 may include one or more of the data in the member profile 302, as described in
With the training data 1012 and the identified features 1002, the machine-learning tool is trained at operation 1014. The machine-learning tool appraises the value of the features 1002 as they correlate to the training data 1012. The result of the training is the trained machine-learning program 1016.
When the machine-learning program 1016 is used to generate a score, new data, such as member data 1018, is provided as an input to the trained machine-learning program 1016, and the machine-learning program 1016 generates the score 1020 as output. For example, when a member performs a job search, a machine-learning program, such as the machine-learning program 1016, trained with similarity data, such as from the similarity database 134, uses the member data and job data from the jobs in the job database 128 to search for jobs that match the member's profile 302 and activity.
The machine-learning program 1016 may be used to determine a similarity score between the searching member 160 and a proxy member of the social network based on a comparison of skills between the searching member 160 and the proxy member. As discussed above, in some example embodiments, this similarity score is used with other similarity scores from other proxy members to calculate a job-interaction score for each job.
Some example embodiments are presented for comparing member skills, but the same principles may be applied by comparing other features in addition to the skills, such as title, position, years of experience, etc., or any combination thereof. In some example embodiments, semantic vectors are created for the skills of members, and in other embodiments, the semantic vectors include the skills, the title, and the job function, for example.
Reducing vector dimension from a sparse vector representation to a compressed vector representation may be done in several ways. In one embodiment, the skills and title of each member are placed within a row, and then matrix factorization is utilized to reduce the vectors to a smaller dimension, such as 50 or 100. Then, on the reduced-dimension pace, a nearest neighbor computation from the member is performed, and can optionally be restricted to members that have engaged in member interactions with at least one job (good candidate proxy members). This way, proxy members with similar skills are found.
As used herein, the similarity coefficient between a first skill vector and a second skill vector is a real number that quantifies a similarity between the skills of the first member and the skills of the second member. The similarity coefficient is also referred to herein as the similarity value. In some example embodiments, the similarity coefficient is in the range of 0 to 1, but other ranges are also possible. In some embodiments, cosine similarity is utilized to calculate the similarity coefficient between the skill vectors.
In some example embodiments, the skill data in the skill table 1102 includes a skill identifier (e.g., an integer value) and a skill description text (e.g., C++). The member profiles 302 are linked to the skill identifier, in some example embodiments.
Semantic analysis finds similarities among member skills by creating a vector for each member such that members with similar skills have skill vectors 1108 near each other. In one example embodiment, the tool Word2vec is used to perform the semantic analysis, but other tools may also be used, such as Gensim, Latent Dirichlet Allocation (LDA), or Tensor flow.
These models are shallow, two-layer neural networks that are trained to reconstruct linguistic contexts of words. Word2vec takes as input a large corpus of text and produces a high-dimensional space (typically between a hundred and several hundred dimensions). Each unique word in the corpus is assigned a corresponding vector in the space. The vectors are positioned in the vector space such that words that share common contexts in the corpus are located in close proximity to one another in the space. In one example embodiment, each element of the skill vector 1108 is a real number.
Initially, a simple skill vector 1110 is created for each skill, where each simple skill vector 1110 includes a plurality of zeros and a 1 at the location corresponding to the skill. Afterwards, a concatenated skill table 1102 included in the member features 1004 is created, where each row includes a sequence with all the skills for a corresponding member. Thus, the first row of concatenated skill table 1102 includes all the simple skill vectors 1110 for the skills of the first member, the second row includes all the simple skill vectors 1110 for the skills of the second member, and so forth.
A semantic analysis operation 1106 is then performed on the concatenated skill table 1104. In one example embodiment, Word2vec is utilized, and the result is compressed skill vectors 1108, or simply referred to as “skill vectors,” such that members with similar skills have skill vectors 1108 near each other (e.g., with a similarity coefficient below a predetermined threshold).
Using these models, the system can determine a similarity score for a connection between a searching member 160 and a proxy member on the social network. In an example, the similarity score between the searching member 160 and a first proxy member is determined by the machine-learning program 1016 to be 0.5678 on a scale of 0 to 1. This similarity score can be used, according to the interaction formula, to weight the various interactions that the first proxy member has with a first job. Based on these weighted interactions and the weighted interactions from other proxy members, a job-interaction score for the first job can be determined.
The communication component 1210 provides various data retrieval and communications functionality. In example embodiments, the communication component 1210 retrieves data from the databases 132, 128, 130, and 134 including member data, jobs, group data, interaction features 1008, job features 1006, and member features 1004. The communication component 1210 can further retrieve data from the databases 132, 128, 130, and 134 related to rules such as threshold data, data related to a maximum number of employees to be used for generating relation scores 902 with the searching member 160, and data related to the maximum quantity of jobs displayable within the trending-jobs group area 408.
The analysis component 1220 performs operations such as determining proxy members based on a comparison of skills of the proxy members and of the searching member. This comparison may be performed using machine-learning programs 1016 described in
The scoring component 1230 calculates various scores as illustrated above with reference to
The ranking component 1240 provides functionality to rank jobs by job-interaction score, as determined by the scoring component 1230, within the trending-jobs group. In some example embodiments, the jobs are ranked from highest to lowest job-interactions score.
The presentation component 1250 provides functionality to present a display of the trending-jobs group area 408 including the jobs with a display of the job-interaction score to the searching member 160, such as on the user interface 402.
It is to be noted that the embodiments illustrated in
Operation 1302 is for determining, by a server having one or more processors, a first skill set comprising skills located within the profile of the searching member 160 in response to a job search requested by the searching member 160. This can be accomplished via a machine-learning program 1016. From operation 1302, the method 1300 flows to operation 1304, where the server identifies a plurality of job listings (jobs) that are currently active and presentable to the searching member 160, each job being offered by a respective company. From operation 1304, the method 1300 flows to operation 1306, where the server identifies proxy members for each job based on a similarity of skills contained in the first skill set (from the searching member 160) and the profile of each proxy member. From operation 1306, the method 1300 flows to operation 1308, where the server calculates a job-interaction score based on interactions by proxy members with the jobs over a predetermined period of time. The interactions can include, but are not limited to, job page views, job applications, and job shares. In some embodiments, the job-interaction score is further based on a similarity score between the searching member 160 and the respective proxy members. The method 1300 then flows to operation 1310 where the jobs are ranked by the server based on the job-interaction score of each job. Finally, the method 1300 flows to operation 1312, where the system causes presentation of the jobs within the trending-jobs group area 408 based on the ranking of the jobs by trending jobs score.
In alternative embodiments, the machine 1400 operates as a standalone device or may be coupled (e.g., networked) to other machines. In a networked deployment, the machine 1400 may operate in the capacity of a server machine or a client machine in a server-client network environment, or as a peer machine in a peer-to-peer (or distributed) network environment. The machine 1400 may comprise, but not be limited to, a switch, a controller, a server computer, a client computer, a personal computer (PC), a tablet computer, a laptop computer, a netbook, a set-top box (STB), a personal digital assistant (PDA), an entertainment media system, a cellular telephone, a smart phone, a mobile device, a wearable device (e.g., a smart watch), a smart home device (e.g., a smart appliance), other smart devices, a web appliance, a network router, a network switch, a network bridge, or any machine capable of executing the instructions 1410, sequentially or otherwise, that specify actions to be taken by the machine 1400. Further, while only a single machine 1400 is illustrated, the term “machine” shall also be taken to include a collection of machines 1400 that individually or jointly execute the instructions 1410 to perform any one or more of the methodologies discussed herein.
The machine 1400 may include processors 1404, memory/storage 1406, and I/O components 1418, which may be configured to communicate with each other such as via a bus 1402.

The term “processor” is intended to include multi-core processors that may comprise two or more independent processors (sometimes referred to as “cores”) that may execute instructions contemporaneously. Although
The memory/storage 1406 may include a memory 1414, such as a main memory, or other memory storage, and a storage unit 1416, both accessible to the processors 1404 such as via the bus 1402. The storage unit 1416 and memory 1414 store the instructions 1410 embodying any one or more of the methodologies or functions described herein. The instructions 1410 may also reside, completely or partially, within the memory 1414, within the storage unit 1416, within at least one of the processors 1404 (e.g., within the processor's cache memory), or any suitable combination thereof, during execution thereof by the machine 1400. Accordingly, the memory 1414, the storage unit 1416, and the memory of the processors 1404 are examples of machine-readable media.
As used herein, “machine-readable medium” means a device able to store instructions and data temporarily or permanently and may include, but is not limited to, random-access memory (RAM), read-only memory (ROM), buffer memory, flash memory, optical media, magnetic media, cache memory, other types of storage (e.g., Erasable Programmable Read-Only Memory (EEPROM)), and/or any suitable combination thereof. The term “machine-readable medium” should be taken to include a single medium or multiple media (e.g., a centralized or distributed database, or associated caches and servers) able to store the instructions 1410. The term “machine-readable medium” shall also be taken to include any medium, or combination of multiple media, that is capable of storing instructions (e.g., instructions 1410) for execution by a machine (e.g., machine 1400), such that the instructions, when executed by one or more processors of the machine (e.g., processors 1404), cause the machine to perform any one or more of the methodologies described herein. Accordingly, a “machine-readable medium” refers to a single storage apparatus or device, as well as “cloud-based” storage systems or storage networks that include multiple storage apparatus or devices. The term “machine-readable medium” excludes signals per se.
The I/O components 1418 may include a wide variety of components to receive input, provide output, produce output, transmit information, exchange information, capture measurements, and so on. The specific I/O components 1418 that are included in a particular machine will depend on the type of machine. For example, portable machines such as mobile phones will likely include a touch input device or other such input mechanisms, while a headless server machine will likely not include such a touch input device. It will be appreciated that the I/O components 1418 may include many other components that are not shown in
In further example embodiments, the I/O components 1418 may include biometric components 1430, motion components 1434, environmental components 1436, or position components 1438 among a wide array of other components. For example, the biometric components 1430 may include components to detect expressions (e.g., hand expressions, facial expressions, vocal expressions, body gestures, or eye tracking), measure biosignals (e.g., blood pressure, heart rate, body temperature, perspiration, or brain waves), identify a person (e.g., voice identification, retinal identification, facial identification, fingerprint identification, or electroencephalogram-based identification), and the like. The motion components 1434 may include acceleration sensor components (e.g., accelerometer), gravitation sensor components, rotation sensor components (e.g., gyroscope), and so forth.

The operating system 1520 may manage hardware resources and provide common services. The operating system 1520 may include, for example, a kernel 1518, services 1522, and drivers 1524. The kernel 1518 may act as an abstraction layer between the hardware and the other software layers. For example, the kernel 1518 may be responsible for memory management, processor management (e.g., scheduling), component management, networking, security settings, and so on. The services 1522 may provide other common services for the other software layers. The drivers 1524 may be responsible for controlling or interfacing with the underlying hardware. For instance, the drivers 1524 may include display drivers, camera drivers, Bluetooth® drivers, flash memory drivers, serial communication drivers (e.g., Universal Serial Bus (USB) drivers), Wi-Fi® drivers, audio drivers, power management drivers, and so forth depending on the hardware configuration.
The libraries 1516 may provide a common infrastructure that may be utilized by the applications 1512 and/or other components and/or layers. The libraries 1516 typically provide functionality that allows other software modules to perform tasks in an easier fashion than by interfacing directly with the underlying operating system 1520 functionality (e.g., kernel 1518, services 1522, and/or drivers 1524). The libraries 1516 may include system libraries 1542 (e.g., C standard library) that may provide functions such as memory allocation functions, string manipulation functions, mathematic functions, and the like. In addition, the libraries 1516 may include API libraries 1544 such as media libraries (e.g., libraries to support presentation and manipulation of various media formats such as MPEG4, H.264, MP3, AAC, AMR, JPG, PNG), graphics libraries (e.g., an OpenGL framework that may be used to render two-dimensional and three-dimensional graphic content on a display), database libraries (e.g., SQLite that may provide various relational database functions), web libraries (e.g., WebKit that may provide web browsing functionality), and the like. The libraries 1516 may also include a wide variety of other libraries 1546 to provide many other APIs to the applications 1512 and other software components/modules.
The frameworks 1514 (also sometimes referred to as middleware) may provide a higher-level common infrastructure that may be utilized by the applications 1512 and/or other software components/modules. For example, the frameworks 1514 may provide various graphic user interface (GUI) functions, high-level resource management, high-level location services, and so forth. The frameworks 1514 may provide a broad spectrum of other APIs that may be utilized by the applications 1512 and/or other software components/modules, some of which may be specific to a particular operating system or platform.
The applications 1512 include job-scoring applications 1562, job search/suggestions 1564, built-in applications 1536, and third-party applications 1538. The job-scoring applications 1562 comprise the job-scoring applications, as discussed above with reference to
The applications 1512 may utilize built-in operating system functions (e.g., kernel 1518, services 1522, and/or drivers 1524), libraries (e.g., system libraries 1542, API libraries 1544, and other libraries 1546), or frameworks/middleware 1516 to create user interfaces to interact with users of the system. Alternatively, or additionally, in some systems, interactions with a user may occur through a presentation layer, such as the presentation layer 1510. In these systems, the application/module “logic” can be separated from the aspects of the application/module that interact with a user.
