The present disclosure relates to a field of search engine technologies, and more particularly to a search result aggregation method and apparatus based on artificial intelligence and a search engine.
With the rapid development of the computer network technology, a search engine gradually becomes a most important, fast and convenient mode for people to obtain information. After a user inputs a query in the search engine, the search engine can return a search result of the query.
At present, a conventional search engine usually provides a plurality of search results and abstracts related to the query based on the query input by the user, that is, the user's demand is satisfied in a way similar to information retrieval. When clicking a link corresponding to the search result, the user may view page content of the search result, to find and summarize the answer.
However, there are following problems: (1) within the search results obtained in the above way, it is easy to occur homogenization phenomenon of several search results, increasing user's click cost; (2) since the search results obtained are mixed-up, the results are poorly readable, increasing user's lookup cost; (3) a search demand of the user is not analyzed, such that for a relatively complex problem, only one or two results may not meet the search demand of the user, resulting in poor search experience.

Additional aspects and advantages of embodiments of the present disclosure will be given in part in the following descriptions, and become apparent in part from the following descriptions, or be learned from the practice of the embodiments of the present disclosure.
These and other additional aspects and advantages of embodiments of the present disclosure will become apparent and more readily appreciated from the following descriptions made with reference to the drawings, in which:
Description will be made in detail below to embodiments of the present disclosure. Examples of embodiments are illustrated in the accompanying drawings, in which, the same or similar numbers represent the same or similar elements or elements with the same or similar functions. Embodiments described below with reference to the accompanying drawings are exemplary, which are intended to explain the present disclosure and do not be understood a limitation of the present disclosure.
At present, a conventional search engine usually gives N pieces of search results (for example URL (Uniform Resource Locator) addresses) and abstracts based on the query input by the user, that is, the user's demand is satisfied in a way similar to information retrieval. However, this “find-it and fix-it mentality” method in nowadays is obviously unable to keep up with the user demand. Especially, the problems faced today are more and more complicated, and any knowledge has a plurality of extension meanings besides its own connotation. The same is true for demand, for example, the user inputs a query “Andy Lau”, and then in addition to the demand of the knowledge encyclopedia type, there are a plurality of potential demands such as pictures, videos, audio, news, and the priorities of the demands will vary from person to person. Since the screen is large on the PC side, the amount of information that can be carried is large, and by showing a diversity of results, this problem may be solved to some extent. However, for a mobile terminal, hardware such as a screen size and an input mode of the mobile terminal is limited, such that click and input costs of the user are increased. Therefore, the present disclosure provides a search result aggregation method and apparatus based on artificial intelligence and a search engine. In detail, the search result aggregation method and apparatus based on artificial intelligence and the search engine provided in embodiments of the present disclosure will be described with reference to the accompanying drawings.
In block S110, a query is obtained.
For example, it is assumed that the search result aggregation method based on artificial intelligence provided in embodiments of the present disclosure is applicable to a search engine. The search engine may provide an input interface for the user, such that the user may input the query via the input interface. When it is detected that the user inputs the query via the input interface, the query may be obtained. The query may include but not limited to Chinese, letters, Japanese, Korean, numbers, special characters (such as @, {circumflex over ( )}, etc.). In addition, the query may be a Chinese character text input by the user, and further may be a speech input by the user.
In block S120, a plurality of search results is generated according to the query.
In detail, after obtaining the query, searching may be performed according to the query, to find a plurality of search results corresponding to the query.
In block S130, a plurality of corresponding demand dimensions are obtained according to the query.
It should be understood that, there are a plurality of ways to obtain the plurality of corresponding demand dimensions according to the query. For example, online analysis may be performed on the query, that is, demand analysis is performed on the query online, to obtain the plurality of demand dimensions corresponding to the query. As another example, a large amount of queries and the corresponding plurality of demand dimensions may be first collected by offline analysis, that is, a comparison table of queries and demand dimensions is generated, such that when a query of a target user is obtained, the plurality of demand dimensions corresponding to the query are searched for in the pre-generated comparison table of queries and demand dimensions.
As an example, the comparison table of queries and demand dimensions may be obtained firstly, and then the searching is performed in the comparison table of queries and demand dimensions according to the query to obtain the plurality of demand dimensions corresponding to the query.
It should be understood that, there are a plurality of ways to generate the comparison table of queries and demand dimensions. For example, the demand dimensions may be mined according to user's active behavior change information in user session information; as another example, the demand dimensions may be mined based on Title and URL information.
As an example, as illustrated in
In block S210, the user session information of a plurality of users is obtained.
Since there are massive data existing on the Internet, this characteristic of the Internet may be used to obtain the user session information generated by a large number of sample users using the search engine. It should be understood that, the user session information may include but not limited to queries input by the sample users.
In block S220, demand mining is performed according to the users' active behavior change information in the user session information, to generate the plurality of demand dimensions.
It should be understood that, the user session information may include the plurality of queries input by the user, and there is a correlation among the plurality of queries. Therefore, summarizing is performed on the queries input by the plurality of users according to the correlation among the plurality of the queries, and then the demand mining may be performed for the active behavior change of those queries with the correlation to obtain the plurality of demand dimensions. For example, taking user session information={Andy Lau, Andy Lau movie, Andy Lau movie download} as an example, it may be seen that, the user session information may include queries “Andy Lau”, “Andy Lau movie” and “Andy Lau movie download”, and there is a correlation among the three queries, in which, “movie” is a demand dimension of “Andy Lau”, and “download” is a demand dimension of “Andy Lau movie”. Therefore, the demand dimension mining may be realized according to the user's active behavior change in the user session information.
In block S230, a correspondence relationship between queries in the user session information and the plurality of demand dimensions is established.
In block S240, the comparison table of queries and demand dimensions is generated according to the plurality of demand dimensions, the queries in the user session information and the correspondence relationship.
In other words, summarizing may be performed on the plurality of demand dimensions and the queries in the user session information according to the foregoing correspondence relationship, to obtain the comparison table of queries and demand dimensions.
As another example, as illustrated in
In block S310, user session information of a plurality of users is obtained.
In block S320, a set of potential demand-related terms is mined according to a syntactic structure of queries in the user session information.
In block S330, the set of potential demand-related terms is mined and supplemented according to station information corresponding to urls (uniform resource locator) in the search results corresponding to the queries in the user session information.
In block S340, the plurality of demand dimensions is selected and determined according to a statistic characteristic of the set of potential demand-related terms.
In block S350, the correspondence relationship between the queries in the user session information and the plurality of demand dimensions is established.
In block S360, the comparison table of queries and demand dimensions is generated according to the plurality of demand dimensions, the queries in the user session information and the correspondence relationship.
In block S140, aggregation is performed on the plurality of demand dimensions according to the plurality of search results.
In detail, in embodiments of the present disclosure, the aggregation may be performed on the plurality of demand dimensions according to the plurality of search results as follows. Firstly, syntactic structures of titles and abstracts in the plurality of search results are analyzed, and station information and webpage types corresponding to urls in the plurality of search results are analyzed. Finally, the plurality of demand dimensions are aggregated according to the syntactic structures of the titles, the syntactic structures of the abstracts, the station information and the webpage types.
In detail, in the plurality of search results, each search result includes a title, an abstract and url information. Afterwards, the syntactic structures of the titles, the syntactic structures of the abstracts, the station information of the urls and the webpage types corresponding to the urls are respectively extracted according to those information. Then, the aggregation is performed on the plurality of demand dimensions corresponding to the query according to these analysis results, to aggregate the same or similar demands. For example, “why” and “the cause” have demands of the same meaning, “how to do” and “how to solve” have demands of the same meaning, and “where to repair” and “breakdown maintenance” have demands of the same meaning, and the like.
In block S150, the answer corresponding to each demand dimension is obtained, and the answers corresponding to the plurality of demand dimensions is aggregated according to the aggregated demand dimensions to generate an aggregation result.
In detail, answer content corresponding to each demand dimension is obtained from the plurality of search results, and then the answer corresponding to each demand dimension is mapped to the aggregated demand dimensions, and the answers mapped to the same demand dimension are aggregated together to generate the aggregation result. For example, taking a query “Xiaomi 4 restarts automatically” as an example, then under the “breakdown cause” demand dimension, search result content may mention a plurality of similar opinions, for example “software is not compatible”, and “mobile phone hardware has a problem”. Aggregation is performed on the answer contents under the “breakdown cause” demand dimension by the content aggregation, to obtain result aggregation content under the demand dimension. It should be understood that, in order to avoid redundancy of the result content, after aggregating the answers corresponding to the plurality of demand dimensions according to the aggregated demand dimensions, normalization is performed on the aggregated results, to avoid that the same contents appear repeatedly.
In more detail, in the plurality of search results, each search result includes a title, an abstract and url information, and the syntactic structures of the titles, the syntactic structures of the abstracts, the station information of the urls and the webpage types corresponding to the urls are respectively extracted according to those information. Then, a machine learning model is established based on a great amount of user session information according to those analysis results, to map each search result to a certain demand dimension (such as the foregoing aggregated demand dimension). Finally, the results mapped to the same demand dimension are aggregated together, to obtain the aggregation result.
In detail, aggregating the answers corresponding to the plurality of demand dimensions according to the aggregated demand dimension is the typical machine learning process in artificial intelligence. Firstly, a characteristic set is extracted according to the titles, the abstracts and the url information of the search results, in which the characteristic set includes but not limited to semantic characteristic, synaptic structure characteristic, demand-related term characteristic, and url station type characteristic. The ordinary skilled in the art may adjust the characteristic set according to the completeness of existing user session data, semantics, and page classification tools. Afterwards, the characteristic set is extracted with respect to the great amount of user session information with demand dimension marking, and multiple classifiers are trained to learn a mapping relationship between the characteristic set and a set of demand dimensions. The multiple classifiers used in this block may be a traditional learning model taking a support vector machine as an example, an integrated machine learning model taking random forest as an example, or a complex machine learning model taking deep neural networks as an example. The ordinary skilled in the art may select a suitable model by trying and comparing according to data quantity, characteristic quantity and computer device performance. Finally, after the plurality of search results are obtained according to the query, the characteristics are extracted with respect to the plurality of search results and are mapped by the multiple classifiers, such that the demand dimension corresponding to each search result may be known, and the aggregation is finished according to whether the demand dimensions are same.
For example, taking the query “Andy Lau” as an example, there are two results titled “Andy Lau's latest movie watch online” and “Andy Lau's classic movie watch” in the plurality of search results. By analyzing syntax of the title, it may be known that a demand-related term of both results is “watch”, and the station of urls is online video site. The trained machine learning model may simultaneously map the two results to a “video” demand dimension according to those characteristics. Finally, the two results are aggregated together due to being mapped to the same demand dimension. It should be understood that, in a way as illustrated in this example, the aggregation may be performed on the plurality of search results, such that one or more search results may be associated with each demand dimension associated with the query.
Therefore, by multi-level analysis on search demands and results, the search results are re-aggregated and displayed, which may link to a server accurately while satisfying the user's information demand. For example, under a “maintenance merchant” dimension, the search results may directly give an address of an official maintenance shop, or even a customer service platform. It should be understood that, different service contents may be provided for the user according to different demand dimensions, for example question answer content, purchase information content, and maintenance service content.
In order to enable the skilled in the art to know about the present disclosure more clearly, examples will be made below.
For example, taking a query “Kris Wu” as an example, after obtaining the query “Kris Wu”, a plurality of corresponding search results may be generated according to the query, and a plurality of corresponding demand dimensions are queried from the comparison table of queries and demand dimensions according to the query, for example, “knowledge encyclopedia” demand dimension, “star trip” demand dimension, “fan focus” dimension, “star Weibo” dimension, “image” dimension, “news” dimension, etc. Then, the plurality of demand dimensions are aggregated according to the plurality of search results obtained above, that is, classification is performed on the plurality of demand dimensions according to the search results, and that is, the demand dimensions with the same meaning are classified into one category, to finish the aggregation of the plurality of demand dimensions. Then, answer content corresponding to each demand dimension (that is, a demand dimension obtained first) may be obtained from the plurality of search results. Finally, the aggregation is performed on answers corresponding to respective demand dimensions according to aggregated demand dimensions, to obtain the aggregation result. For example, as illustrated in
As another example, taking a query “Beijing's weather”, after obtaining the query “Beijing's weather”, a plurality of corresponding search results may be generated according to the query, and a plurality of corresponding demand dimensions are queried from the comparison table of queries and demand dimensions according to the query, for example, “Real-time weather” demand dimension, “life index” demand dimension, in which the “life index” demand dimension may further include “food” demand dimension, “dressing” demand dimension, “cultural leisure” demand dimension, “attraction” demand dimension, etc. Then, the plurality of demand dimensions are aggregated according to the plurality of search results obtained above, that is, classification is performed on the plurality of demand dimensions according to the search results, and that is, the demand dimensions with the same meaning are classified into one category, to finish the aggregation of the plurality of demand dimensions. Then, answer content corresponding to each demand dimension (that is, a demand dimension obtained first) may be obtained from the plurality of search results. Finally, the aggregation is performed on answers corresponding to respective demand dimensions according to aggregated demand dimensions, to obtain an aggregation result. For example, as illustrated in
In conclusion, with the search result aggregation method based on artificial intelligence provided in embodiments of the present disclosure, the search demands of the user are aggregated on the demand dimension firstly. For a single-demand problem, by multiple-dimension analysis of the results, the search results are classified and arranged, and dimension characteristics are extracted, to achieve accurate satisfaction of information and accurate offer of services. For a multiple-demand problem, the demands are classified and aggregated firstly, and then displayed in levels, such that the user may find what he wants without having to re-launch a new search. Thus, when the single-demand problem is satisfied, related questions and related results are recommended intelligently, to give the user an immersive experience. For example, the user inputs “Xiaomi restarts automatically”, and a plurality of demands such as “malfunction cause”, “solutions”, “maintenance merchants” are obtained by demand analysis and aggregation; for “solutions”, a plurality of demand dimensions such as “Xiaomi 3” and “Xiaomi4” may be obtained; for a specified dimension, for example “solutions of Xiaomi4”, a plurality of practical solutions such as “underlay the battery end with paper”, “press the battery holder gold finger”, “plug in the charger” may be summarized by aggregating and concluding the results, such that the practical problem of the user may be solved in multiple levels and multiple dimensions.

The method has at least following advantages: (1) the results are de-duplicated, cross-validated, reordered and the like by means of aggregation, which reduces repeated click behaviors of the user, and also provides the aggregation result as a reference to assist the user in making decisions; (2) by aggregating the demand dimensions corresponding to the query and aggregating result contents of each demand dimension, i.e., re-aggregating mixed-up results, the search results have a clear logic, clear levels, and are easy to be browsed, which helps users find what they want faster.
In embodiments of the present disclosure, in order to improve the search experience of the user, and enable the user to find what he wants in an immersive browsing experience, related results of other dimensions may be given by means such as guidance and excitation. In detail, as illustrated in
