Patent Application
20190130038
The disclosure relates generally to network crawling systems and particularly to network crawling systems that capture information for personalized news recommendation engines.
With the advent of the Internet, the amount of information can be accessed is becoming difficult to manage. In order to classify the large amounts of information, personalized news recommendation engines use network crawling software and hardware that identifies a website and then classifies information in the website; this allows a personalized news recommendation engine to identify which websites match certain search criteria.
Moreover, because of the vast amounts of information on the Internet, crawling the Internet to identify specific types of information can very processor intensive, which may interfere with other processes associated with personalized news recommendation engines.
In addition, information that is on different websites is typically formatted in different computer formats that are specific to each website. For example, a title of documents one webpage may be in Extended Markup Language (XML) and the title of a second document may be in Portable Document Format (PDF). Moreover, the location of a title within the information on one webpage may be in a different location than a title on a second webpage. Because the format/location of information on different webpages may vary dramatically, this can cause problems when trying to identify specific types of information on a website, such as, a title of a document or a tile of a news story.
These and other needs are addressed by the various embodiments and configurations of the present disclosure. A network crawler crawls one or more media sites to extract a plurality of titles for information contained in the one or more media sites. For example, the network crawler may extract the titles on the one or more media sites by identifying different computer formats and converting the titles in the different computer formats into a common computer format for comparison. User profiles, which include user's interests, are stored in a user profile interest database. A novel personalized news recommendation engine recommends news based on the interest specified in a user profile. The engine applies maximum weighted matching to score the similarity of news against user interest in the word2vec space.
The phrases “at least one”, “one or more”, “or”, and “and/or” are open-ended expressions that are both conjunctive and disjunctive in operation. For example, each of the expressions “at least one of A, B and C”, “at least one of A, B, or C”, “one or more of A, B, and C”, “one or more of A, B, or C”, “A, B, and/or C”, and “A, B, or C” means A alone, B alone, C alone, A and B together, A and C together, B and C together, or A, B and C together.
The term “a” or “an” entity refers to one or more of that entity. As such, the terms “a” (or “an”), “one or more” and “at least one” can be used interchangeably herein. It is also to be noted that the terms “comprising”, “including”, and “having” can be used interchangeably.
The term “automatic” and variations thereof, as used herein, refers to any process or operation, which is typically continuous or semi-continuous, done without material human input when the process or operation is performed. However, a process or operation can be automatic, even though performance of the process or operation uses material or immaterial human input, if the input is received before performance of the process or operation. Human input is deemed to be material if such input influences how the process or operation will be performed. Human input that consents to the performance of the process or operation is not deemed to be “material”.
Aspects of the present disclosure may take the form of an entirely hardware embodiment, an entirely software embodiment (including firmware, resident software, micro-code, etc.) or an embodiment combining software and hardware aspects that may all generally be referred to herein as a “circuit,” “module” or “system.” Any combination of one or more computer readable medium(s) may be utilized. The computer readable medium may be a computer readable signal medium or a computer readable storage medium.
A computer readable storage medium may be, for example, but not limited to, an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus, or device, or any suitable combination of the foregoing. More specific examples (a non-exhaustive list) of the computer readable storage medium would include the following: an electrical connection having one or more wires, a portable computer diskette, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or Flash memory), an optical fiber, a portable compact disc read-only memory (CD-ROM), an optical storage device, a magnetic storage device, or any suitable combination of the foregoing. In the context of this document, a computer readable storage medium may be any tangible medium that can contain, or store a program for use by or in connection with an instruction execution system, apparatus, or device.
A computer readable signal medium may include a propagated data signal with computer readable program code embodied therein, for example, in baseband or as part of a carrier wave. Such a propagated signal may take any of a variety of forms, including, but not limited to, electro-magnetic, optical, or any suitable combination thereof. A computer readable signal medium may be any computer readable medium that is not a computer readable storage medium and that can communicate, propagate, or transport a program for use by or in connection with an instruction execution system, apparatus, or device. Program code embodied on a computer readable medium may be transmitted using any appropriate medium, including but not limited to wireless, wireline, optical fiber cable, RF, etc., or any suitable combination of the foregoing.
The terms “determine”, “calculate” and “compute,” and variations thereof, as used herein, are used interchangeably and include any type of methodology, process, mathematical operation or technique.
The term “Session Initiation Protocol” (SIP) as used herein refers to an IETF-defined signaling protocol, widely used for controlling multimedia communication sessions such as voice and video calls over Internet Protocol (IP). The protocol can be used for creating, modifying and terminating two-party (unicast) or multiparty (multicast) sessions consisting of one or several media streams. The modification can involve changing addresses or ports, inviting more participants, and adding or deleting media streams. Other feasible application examples include video conferencing, streaming multimedia distribution, instant messaging, presence information, file transfer and online games. SIP is as described in RFC 3261, available from the Internet Engineering Task Force (IETF) Network Working Group, November 2000; this document and all other SIP RFCs describing SIP are hereby incorporated by reference in their entirety for all that they teach.

The preceding is a simplified summary to provide an understanding of some aspects of the disclosure. This summary is neither an extensive nor exhaustive overview of the disclosure and its various embodiments. It is intended neither to identify key or critical elements of the disclosure nor to delineate the scope of the disclosure but to present selected concepts of the disclosure in a simplified form as an introduction to the more detailed description presented below. As will be appreciated, other embodiments of the disclosure are possible utilizing, alone or in combination, one or more of the features set forth above or described in detail below. Also, while the disclosure is presented in terms of exemplary embodiments, it should be appreciated that individual aspects of the disclosure can be separately claimed.
The communication devices 101A-101N can be or may include any device that can communicate on the network 110 and request a network search, such as a Personal Computer (PC), a telephone, a video system, a cellular telephone, a Personal Digital Assistant (PDA), a tablet device, a notebook device, a smart phone, a server, a communication system, and/or the like. As shown in
The communication device 101A further comprises a browser 102A. The browser 102A can be any type of browser 102, such as, Firefox™, Google Chrome™, Opera™, Internet Explorer™, Safari™ and/or the like. The browser 102A is used to communicate with the webserver 121. Although not shown, the communication devices 101B-101N may also comprise the browser 102.
The network 110 can be or may include any collection of communication equipment that can send and receive electronic communications, such as the Internet, a Wide Area Network (WAN), a Local Area Network (LAN), a Voice over IP Network (VoIP), the Public Switched Telephone Network (PSTN), a packet switched network, a circuit switched network, a cellular network, a combination of these, and the like. The network 110 can use a variety of electronic protocols, such as Ethernet, Internet Protocol (IP), Session Initiation Protocol (SIP), Integrated Services Digital Network (ISDN), Hyper Text Markup Language (HTML), Web Real-time Communication (WebRTC) protocol, Java script, and the like. Thus, the network 110 is an electronic communication network configured to carry messages via packets and/or circuit switched communications.
The network search system 120 can be or may include any hardware coupled with software that can provide search services on the network 110, such as a server, a communication system, and/or the like. The network search system 120 further comprises a webserver 121, a personalized news recommendation engine 122, a network crawler 123, a data processor 124, and a user profile interest database 125.
The webserver 121 can be or may include any hardware/software that can provide web services, such as, an Apache™ webserver, a Microsoft Internet Information Services™ server, a NGINX™ server, a Google GWS™ server, and/or the like. Users may communicate with the webserver 121 via the browser 102. For example, a user may enter a Uniform Resource Locator (URL) in the browser 102 and be provided a webpage by the webserver 121 that allows the user to invoke the personalized news recommendation engine 122.
The personalized news recommendation engine 122 can be or may include any hardware coupled with software that can search through data based on search criteria. For example, the personalized news recommendation engine 122 may search though data crawled from the media sites 130A-130N by the network crawler 123.
The network crawler 123 can be or may include any hardware coupled with software that can crawl the network 110 to identify information that is used as input to the data processor 124 and/or personalized news recommendation engine 122. In one embodiment, the network crawler 123 crawls the media sites 130A-130N. In
In one embodiment, the network crawler 123 may comprise multiple network crawlers 123 on different servers that crawl different media sites 130. The output from the multiple network crawlers 123 may be stored in multiple user profile interest databases 125 that are accessed by the data processor 124.
The user profile interest database 125 can be or may include data stored in a non-transitory computer medium, such as a memory or disk. The user profile interest database 125 may be a relational user profile interest database, a file system, an object oriented user profile interest database, a directory service, and/or the like. The user profile interest database 125 may be a cluster of user profile interest database servers located on the network 110 that is external to the network search system 120.
In one embodiment, the network crawler 123 may run on a separate computer thread and/or computer core from the personalized news recommendation engine 122 and the data processor 124. For example, the network crawler 123 may use a separate computer core to crawl the network 110.
In one embodiment, the network crawler 123, the data processor 124, and the personalized news recommendation engine 122 each run on separate threads and/or computer cores. In this embodiment, the network crawler 123 (on a first thread/computer core) crawls the network 110 and stores the crawled information in the user profile interest database 125. The data processor 124 (on a second thread/computer core) process the crawled information to identify specific types of information (e.g., to identify specific types of titles of news media) and stores the results in the user profile interest database 125. The personalized news recommendation engine 122 (on a third thread/computer core) uses stored results from the data processor 124 and applies search criteria to identify specific information (e.g., specific news titles). The results are then displayed to a user.
The media sites 130A-130N may be or can include any hardware coupled with software that provide media services, such as a media server (e.g., a server that has a list of titles of moves/music), a news media site, a social media network (e.g., Facebook™), a media feed (e.g., Twitter™), a document server, a file server, a user profile interest database server, an archive server, and/or the like.
The process starts in step 200. The network crawler 123 identifies one or more media sites 130A-130N to be searched in step 202. The network crawler 123 may identify the one or more media sites 130A-130N in various ways. For example, the network crawler 123 may receive input from a user (e.g., from a user interface) that specifies which media sites 130 to crawl. Alternatively, the network crawler 123 may search the media sites 130A-130N based on a defined list of media sites, based on crawling a media site 130 and determining if the media site 130 has titles, based on specific Internet Protocol (IP) addresses, based on a location (e.g., local media sites 130), based on information in a domain name (e.g., all domain sites that have the word “news” in the domain name), and/or the like.
The network crawler 123 captures title(s) and a URL associated with the respective title in step 204. The URL is used to allow a user to link to the webpage associated with the identified title.
A title may be in various forms. For example, a title may be a sentence that is taken from a document, a webpage, a media feed, and/or the like. The title may be a title of a document, a title of a news report, a title of a movie, a title of a piece of music, and/or the like. A title may be identified from a list of titles. For example, the network crawler 123 may identify a list of documents, a list of music titles, a list of videos, a list of television shows, a list of videos, a list of new reports, and/or the like.
The title may be identified based on a link (e.g., a URL) pointing to a document. For example, the URL www.companyx.com/news/newstory_huricane_harvy may be used to identify a title (newstory_huricane_harvey). In this example, the network crawler 123 uses the first portion of the URL “www.companyx.com/news” as a basis for identifying different news stories (e.g. www.companyx.com/news/newstory_fire_in_newyork) that use the same first portion of the URL to point to a second title.
In addition to the title(s)/URL(s), other information about the title/URL may be captured. For example, a short description of the title may be captured in step 204.
In one embodiment, the captured titles from the media sites 130 may be filtered. For example, news titles that are over two weeks old may be filtered out from the captured titles.
The network crawler 123 stores the title(s) in the user profile interest database 125 along with the respective URL that points to the title in step 206. For example, if the title is for a new news story, the URL points to the new story.
The data processor 124 compares the titles in the user profile interest database 125 in step 208. The data processor 124 compares the titles to each other to determine a similarity between compared titles. The comparison results are then stored in the user profile interest database 125 in step 209.
The network crawler 123 determines if there are additional media sites 130 to be crawled in step 210 (repeat the process). For example, the network crawler 123 may periodically search (e.g., every five minutes) the same media sites 130 to find new titles that may be published on the media sites 130 (e.g., breaking news stories). If the network crawler 123 determines there are not any media sites 130 to be searched in step 210 the process ends in step 212.
Otherwise, if the process is to repeat in step 210, the data processor 124 determines, in step 214, if any titles need to be removed from the user profile interest database 125. For example, a title may be outdated, is no longer relevant, or the URL may have been removed from the media site 130 (i.e., by testing the URLs). The data processor 124 may periodically remove titles so that only current news articles are searched. The process then goes to step 202.
If a search request has not been requested in step 302, the process repeats step 302. Otherwise, if a search request has been initiated by the user (or an application), the personalized news recommendation engine 122 gets the search criteria in step 304 (e.g., football). The personalized news recommendation engine 122 gets, in step 306, the title information that was compared and stored in steps 208/209. The personalized news recommendation engine 122 uses an algorithm to compare the output from step 208 (where the titles are compared to each other) to identify one or more titles that match or are closely related (or none if there is not a match) to the search criteria in step 308. For example, a maximum weighted matching algorithm, such as, a Hungarian algorithm, a simplex algorithm, an auction algorithm, and/or the like may be used to search the identified titles from step 208 to determine which titles match the search criteria.
If one or more titles are identified in step 308, the personalized news recommendation engine 122 sends, in step 310, the one or more titles and the respective URL(s) to the user. For example, the personalized news recommendation engine 122 sends the one or more titles/URLs to the browser 102. This way the user can click on the associated URL to view the article associated with the selected title.
The personalized news recommendation engine 122 determines if the process is completed in step 312. If the process is not completed in step 312, the process goes to step 302. Otherwise, if the process is completed in step 312, the process ends in step 314.
In one embodiment, the search request may be a continuous search request. For instance, the process of
To implement the algorithm, the data processor 124 removes, in step 400, stop words and/or high frequency words from the titles using an Inverse Document Frequency (IDF). Stop words/high frequency words are words that are most commonly used in a specific language. For example, if the language English, common stop words, such as, “the,” “is,” “at,” “which,” “on,” and/or the like are removed in step 400. Likewise, for different languages, different stops words would be removed in step 400 according to the specific language. A user may define high frequency words based on a specific context. For example, if the search field (e.g., football) uses specific high frequency words that are not relevant to the search, the user can define specific words to be a stop words or high frequency words.
The data processor 124 compares, in step 402, the titles to each other using one of the algorithms defined in steps 404 or 406. For example, if there are three titles (title A, title B, and title C), the following comparisons would be made: A-B, A-C, and B-C in steps 404 and 406.
In step 404, the data processor 124 applies a minimum cost flow maximum algorithm to find the maximum sum weighted match between two titles. This assumes that the algorithm matched word 1, word 2, . . . , word N in title 1 to vector 1, vector 2, . . . , vector N in title 2. The similarity of title 1 to title 2=Sum (cosine_similarity(word2vec(w1), word2vec(v1))/n where n is the number of words in the title (title 1 or title 2) that has the least number of words. In step 404, the number of words is after the stop words/high frequency words are removed from the two titles.
In step 406, the data processor 124 applies a minimum cost flow maximum algorithm to find the maximum sum weighted match between two titles. This assumes that the algorithm matched word 1, word 2, . . . , word N in title 1 to vector 1, vector 2, . . . , vector N in title 2. The IDF of the title similarity between title 1 and title 2=Sum (cosine_similarity(word2vec(w1), word2vec(v1)*square_root (IDF(w1)*IDF(v1)))/n where n is the number of words in the title (title 1 or title 2) that has the least number of words. In step 406, the number of words is after the stop words/high frequency words are removed from the two titles. After step 404 or step 406 has been completed, the process then goes to step 209.
The network crawler 123 determines the format of the media site 130 in step 502 to identify title(s)/URL(s). For example, the media site 130 may have an Application Programming Interface (API) that allows the network crawler 123 to extract the title and a URL associated with the title. In one embodiment, the network crawler 123 may identify a title on a particular web page based on an identifier (e.g., a tag) within the webpage. For example, the tile may be in the format <title>=“Aftermath of Hurricane Harvey” located in the webpage. In a Microsoft Word™ document, a title can be identified in a specific format within the document. Likewise, in a Hyper Text Markup Language (HTML) webpage, a title may be searched for based on tags. For instance, HTML 5 defines various fields, such as, <header>, <article>, <summary> to identify information in the webpage. HTML 5 also defines the field <nav> where various navigation links (URLs) are defined. The network crawler 123 uses the various formats of the webpages to determine title(s)/URL(s) within a webpage. The network crawler 123 can use the format information to identify specific locations of the title(s)/URL(s) on the webpage.
In one embodiment, the network crawler 123 may have a predefined list of specific formats that are used to identify a title. Based on the list, the network crawler 123 determines how to search a specific webpage. The list may be learned over time.
The network crawler 123 extracts the title(s)/URL(s) from media site 130 based on the website format in step 504. The network crawler 123 can search different webpages that are on a website using well-known network crawling techniques. The network crawler 123 puts the title(s)/URL(s) into a common format for storage in the user profile interest database 125 in step 506. For example, the network crawler 123 may place the title(s)/URL(s) in an Extended Markup Language (XML) file for storage in the user profile interest database 125.
The network crawler 123 determines, in step 508, if there are more media sites 130 to be searched. If there are more media sites 130 to be searched in step 508, the process goes back to step 500. If there are not more media sites 130 to be searched in step 508, the process goes to step 206.
