Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be described clearly and completely with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, not all of the embodiments. The components of the embodiments of the present disclosure, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present disclosure, presented in the figures, is not intended to limit the scope of the claimed disclosure, but is merely representative of selected embodiments of the disclosure. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the disclosure without making creative efforts, shall fall within the protection scope of the disclosure.

Generally, after a search request is initiated at a user end, the content of a search result page, which includes a list of search results, may be returned to the user end, where each search result generally includes: the title of the search result web page, a brief introduction to the search result, etc. In some cases, in a search result related to a certain search request (query), related media contents of multiple entities are involved, and the number of media contents related to one entity may be many, and the related media contents of one entity occupy a large part of the display positions in the search result page, so that it is difficult for a user to see a desired search result at a glance.

Based on the research, the present disclosure provides a searching method, a searching device, and a computer storage medium, where after a search request sent by a user terminal is obtained, a server obtains a plurality of target entities matching the search request, generates a multi-entity aggregation result based on the plurality of target entities, and returns the multi-entity aggregation result to the user terminal, so that the user terminal can display the aggregation result of the plurality of target entities matching the search request, and the user can view the plurality of target entities at a time through the aggregation result, thereby quickly locating a target entity interested by the user, improving information search efficiency, and saving search time.

The above-mentioned drawbacks are the results of the inventor after practical and careful study, and therefore, the discovery process of the above-mentioned problems and the solutions proposed by the present disclosure to the above-mentioned problems should be the contribution of the inventor in the process of the present disclosure.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

To facilitate understanding of the present embodiment, first, a search method disclosed in the embodiments of the present disclosure is described in detail, where an execution subject of the search method provided in the embodiments of the present disclosure is generally a computer device with certain computing capability, and the computer device includes, for example: a terminal device, which may be a User Equipment (UE), a mobile device, a User terminal, a cellular phone, a cordless phone, a Personal Digital Assistant (PDA), a handheld device, a computing device, a vehicle mounted device, a wearable device, or a server or other processing device. In some possible implementations, the search method may be implemented by a processor calling computer readable instructions stored in a memory.

Example one

The following describes a search method provided by the embodiments of the present disclosure by taking an execution subject as a server.

Referring to fig. 1, which is a flowchart of a searching method provided in the embodiment of the present disclosure, the method includes steps S101 to S103, where:

s101, obtaining a search request of a user side.

The User terminal may be a terminal device, a server, or other processing devices, and the terminal device may be a User Equipment (UE), a mobile device, a User terminal, a Personal Digital Assistant (PDA), or the like.

Here, the search request may carry search content input by the user, and the search request processed by the embodiment of the present disclosure is related to a plurality of entities, for example, the user searches "female star with a height of 170cm after 90", and this search request corresponds to a plurality of star entities.

In a specific implementation, a user inputs search content on a search interface, after the user clicks a "search" button, a user side generates a search request and sends the search request to a server, and the server obtains the search request of the user and executes the following step S102.

S102, acquiring a plurality of target entities matched with the search request based on the request type of the search request.

The request type of the search request may include an attribute class and an entity set class.

In a possible implementation manner, when the search request is an attribute-type search request, a plurality of target entities matching the search request may be found based on attribute information of different entities in the knowledge graph.

Wherein the attribute-class search request refers to a search request that characterizes a search intention using a plurality of attribute keywords. Such as: when the search content input by the user in the search page is "women star with a height of 170cm after 90", the plurality of attribute keywords "after 90", "height", "170 cm", "women star" herein represent the search intention of the user.

The knowledge graph may be a semantic network formed by a plurality of nodes and connecting edges between the nodes, where the nodes may represent entities, information of the nodes is related information of the corresponding entities, and the connecting edges between the nodes may represent various semantic relationships between the entities, such as a parental relationship, a couple relationship, a broker, a friend, and the like.

Specifically, after acquiring a search request of a user, a server determines a search type of the search request, extracts a plurality of attribute keywords contained in search content corresponding to the search request after determining that the search type of the search request is an attribute type search request, queries a knowledge graph based on the attribute keywords, and determines whether entities matched with the attribute keywords are stored in the knowledge graph; when the knowledge graph stores the entities matched with the attribute keywords, the entities in the knowledge graph, which accord with the search request of the user, can be fed back to the user.

Illustratively, when the search content input by the user in the search page is "female star with a height of 170cm after 90", and the "search" button is clicked, the user side sends the search request to the server, the server receives the search request, determines that the type of the search request is an attribute type search request, extracts a plurality of attribute keywords contained in the search content corresponding to the search request as "90", "height", "170 cm" and "female star", queries a knowledge graph based on the plurality of attribute keywords, can find out stars matching the attributes of the gender, age and height from a plurality of star entities stored in the knowledge graph, and feeds back the information of the found stars to the user.

In another possible implementation manner, when the search request is an entity set type search request, obtaining associated media content corresponding to the search request; determining a plurality of target entities matching the search request based on the associated media content.

Here, the entity set type search request means that the search intention of the search request corresponds to a plurality of entities, but the search intention is not directly characterized by a plurality of attribute keywords. Such as: when the search content is ' a movie suitable for lovers ' to see ', the search content relates to a plurality of movie entities, but the related entity information cannot be found in the knowledge graph through keywords of the lovers and the movie. In this case, a plurality of target entities matching the search content corresponding to the search request are determined in a manner of acquiring the associated media content corresponding to the search request and determining the target entities from the associated media content.

Wherein the associated media content may include one or more of text documents, text-text mixed documents, pictures, audio, video, and the like.

In a specific implementation, the plurality of associated media contents corresponding to the search request may be determined by the following method, which is specifically described as follows: under the condition that the query intention corresponding to the search request is an objective intention, searching for associated media content with objective answers matched with the search request; and under the condition that the query intention corresponding to the search request is the subjective category intention, searching for the associated media content with the subjective category search result matched with the search request.

Here, the query intention type corresponding to the search request may include an objective class intention and a subjective class intention. The related media content containing the objective answers is recalled according to the search request of the objective intention, and the related media content of the published related subjective opinion-like content is recalled according to the search request of the subjective intention. When searching for the associated media content aiming at the two types of search requests, a standard sentence corresponding to the search request can be obtained by adopting a standard semantic extraction mode, and the associated media content matched with the obtained standard sentence is further searched.

Specifically, a standard sentence corresponding to a search sentence in the search request may be determined based on a pre-trained generalization model; and then based on the standard sentence, obtaining the associated media content matched with the search request. The generalized model is obtained by training a large number of search sentence samples marked with standard sentences, and the generalized model can extract keywords from the search sentences and further convert the extracted keywords into the standard sentences.

For example, when the user inputs search content on the search interface: when the "what the four great works are" or "what the four great works contain", a generalization model trained in advance in the server performs keyword extraction on the search content "what the four great works are" or "what the four great works contain", extracts a search keyword "the four great works" corresponding to the search content, and forms a standard sentence "what the four great works are".

Specifically, after receiving a search request of a user, the server inputs search content corresponding to the search request into the generalized model, determines a standard sentence corresponding to the search request, queries a media content library based on the standard sentence, and determines a plurality of associated media content corresponding to the search request.

Illustratively, the search content input by the user in the search interface is: the server inputs the search content "which of the four great names" into the generalized model after the user clicks the "search" button, determines what the standard sentence corresponding to the search content is "what the four great names are", and queries the related media content corresponding to the search content in the media content library based on the standard sentence.

In a specific implementation, after determining the associated media content matching the search request, a plurality of target entities matching the search request may be determined in the associated media content by the following method, which is described in detail as follows:

acquiring a plurality of entities corresponding to each associated media content in the associated media content; clustering and de-duplicating the multiple entities to obtain multiple processed candidate entities; determining the target entity from the plurality of candidate entities.

Here, the server extracts entities of a plurality of media contents in advance, and may store a correspondence between the identifiers of the media contents and the related information of the extracted entities; the extracted related information of the entity may include identification information of the entity, and information such as an entity name and an entity thumbnail. Fig. 2 shows a schematic diagram of an entity extraction result.

In a specific implementation, the obtained multiple candidate entities are ranked, and the target entity is selected from the multiple candidate entities according to a ranking result, and the obtained multiple candidate entities may be ranked in the following manner, which is specifically described as follows: identifying the intention of the user on the acquired search request, and determining intention classification information of the search request; and sequencing the obtained candidate entities according to the intention classification information and the attribute information of each candidate entity.

The attribute information of the candidate entity may include at least one of classification information of the candidate entity, attribute characteristics of associated media content corresponding to the candidate entity, and the number of times that the same entity information appears in different associated media content.

The classification information of the candidate entity may represent the type of the candidate entity, and may include literature, books, movies, art, life, vehicles, automobiles, society, brands, gourmet food, and the like.

Wherein the attribute characteristics of the associated media content may include: attribute information of an author corresponding to the associated media content, a correlation degree between the associated media content and the search request, and a ranking order of the associated media content in the search.

Here, the attribute information of the author corresponding to the associated media content may include author authority, author influence, and the like; the relevance between the associated media content and the search request is used for indicating whether the associated media content meets the search requirement of the user, and the higher the relevance is, the more the associated media content meets the search requirement of the user; the ranking order of the associated media content in the search may be the ranking order of each associated media content in the search result obtained by searching the search request of the user in the search engine, where the higher the ranking, the more in line with the search requirement of the user.

The intention classification information may be used to indicate a requirement corresponding to the search request of the user, that is, a type of content that the user wants to search for, which may be life, transportation, automobile, society, brand, food, and the like; such as: the method comprises the steps that a search content input by a user on a search interface is 'SUV with which chassis is high', intention identification is carried out on the search content, and intention classification information of a search request is determined to be life, vehicles and automobiles; for another example: the method comprises the steps that search content input by a user on a search interface is 'what a world ten-name form has', intention identification is carried out on the search content, and intention classification information of a search request is determined to be a society, a brand and a watch. The rank of candidate entities that match the intent classification information of the search request is higher than the rank of candidate entities that do not match the intent classification information of the search request.

Here, the more times the same candidate entity appears in different associated media content, the more front the candidate entity ranks.

With reference to the above description, in an implementation, after obtaining a search request of a user, a server determines a search type of the search request, and if the search type of the search request is an entity set type search request, obtains a plurality of associated media contents corresponding to the search request; acquiring a plurality of entities corresponding to each associated media content in a plurality of associated media contents, clustering and de-duplicating the acquired entities, and determining a plurality of candidate entities; the server identifies the intention of the user for the acquired search request, determines intention classification information of the search request, sorts the acquired multiple candidate entities according to the intention classification information, the classification information of each candidate entity, the author authority and the author influence of the associated media content respectively corresponding to each candidate entity, the correlation degree between the associated media content respectively corresponding to each candidate entity and the search request, the ranking order of the associated media content respectively corresponding to each candidate entity in the search, the occurrence frequency of the same candidate entity in different associated media contents and the like, and determines multiple target entities matched with the search request of the user according to the sorting result.

In a specific implementation, after determining a plurality of target entities matching the search request in step S102, a multi-entity aggregation result including the plurality of target entities may be generated in step S103, and the multi-entity aggregation result is returned to the user, which is described in detail below.

S103, generating a multi-entity aggregation result based on the target entities, and returning the multi-entity aggregation result to the user side.

The user side can be an electronic device with a display function, such as a mobile phone, a tablet computer, a computer device and the like.

The multi-entity aggregation result may include identification information of a plurality of target entities, encyclopedic knowledge information and recommendation information corresponding to each target entity, at least one associated media content corresponding to each target entity, function entry information corresponding to each target entity, and the like; here, the identification information may include an entity name, an entity thumbnail, and an arrangement order of the entity in a plurality of target entities; an entity thumbnail can be a hyphen of the entity; the recommendation information can be text introduction content, image-text introduction content, video or audio introduction content and the like for the entity, and can also be encyclopedic knowledge content; the associated media content can be media content related to the entity, and can be a text document, a picture-text mixed document, a picture, audio, video and the like; the function entry information may be used to instruct the user to click on a consumption page entering the target entity, where the consumption page may be, for example, a play interface or a purchase page of the target entity.

In a specific implementation, based on the multiple target entities determined in step S102, a multiple entity aggregation result including the multiple target entities is generated, and the multiple entity aggregation result is returned to the user side, so that the user side displays the multiple entity aggregation result to the user, and the user side can display the multiple target entities matching the search request, and then display a search result related to the target entity based on the target entity of interest selected by the user. The user can see a plurality of target entities at a time through the aggregation result, so that the user can conveniently further screen interested target entities and finally display the media contents related to the target entities interested by the user.

Illustratively, the search content input by the user in the search interface is: "which of the four great works" is available, after a user clicks a "search" button, the server judges that the search type of the search request is an entity set type search request, and then the server inputs the "which of the four great works" of the search sentence into a generalization model, determines what the four great works are of a standard sentence corresponding to the search content, and extracts a keyword corresponding to the standard sentence: the four famous works are used for inquiring the media content library based on the keywords, and all the book information, the article information and the movie information which are stored in the media content library and are related to the four famous works, the water business biography, the dream of the Red mansions, the three countries 'rehearsal' and the Western notes are used as a plurality of related media contents; determining a plurality of entities corresponding to a plurality of associated media contents respectively based on the corresponding relation between the identification of the media contents stored by the server and the extracted relevant information of the entities, acquiring a plurality of entities corresponding to each associated media content in the associated media contents, and clustering and de-duplicating the acquired entities to obtain a plurality of processed candidate entities; identifying user intention for the search content corresponding to the received search request, and determining intention classification information corresponding to the search content as literature and books; according to intention classification information, classification information of a plurality of candidate entities, author authority and author influence of associated media contents corresponding to the candidate entities respectively, correlation degree between the associated media contents corresponding to the candidate entities and the search request, arrangement sequence position of the associated media contents corresponding to the candidate entities in the search and frequency of occurrence of the same book information in different associated media contents, the obtained candidate entities are sequenced, and according to sequencing results, a plurality of target entities matched with the search request of the user are determined to be books ' West Yong ' records, ' Shuihu biography, ' three kingdoms ' and ' Hongtou dream ', and the server generates identification information containing the target entities, encyclopedic knowledge information and/or recommendation information corresponding to the target entities, at least one associated media content corresponding to each target entity, and the like on the basis of the target entities, And a multi-entity aggregation result of information such as function entry information corresponding to each target entity is sent to the user side, and the user side can firstly display a plurality of target entities matched with the search request and then display the search result related to the target entities based on the interested target entities selected by the user.

Illustratively, the search content input by the user in the search interface is: "what movies are suitable for lovers at night" is provided, after a user clicks a "search" button, a server judges that the search type of the search request is an entity set type search request, inputs the search content "what movies are suitable for lovers at night" into a generalized model, determines that a standard sentence corresponding to the search content is "movies suitable for lovers at night", and extracts keywords corresponding to the standard sentence: the search library is queried based on the keywords, and the entity results matched with the attributes of the "night", "lovers" and "movies" are determined to be "love june flower", "love notebook", "old and young", "love you nine weeks and half", "blue lover's festival", and articles, movie works, movie comment contents and the like containing the "love june flower", "love notebook", "old and young", "love you nine weeks and half", "blue lover's festival" stored in the search library are taken as related media contents; determining a plurality of entities respectively corresponding to a plurality of associated media contents according to the corresponding relation between the identification of the media contents stored in the server and the extracted relevant information of the entities, acquiring the plurality of entities corresponding to the associated media contents, and clustering and de-duplicating the acquired plurality of entities to obtain a plurality of processed candidate entities; and identifying the user intention of the search content corresponding to the received search request, and determining intention classification information corresponding to the search content as follows: life, entertainment, movies; sorting the obtained multiple candidate entities according to the intention classification information, classification information of the multiple candidate entities, author authority and author influence of the associated media content corresponding to each candidate entity, correlation degree between the associated media content corresponding to each candidate entity and the search request, arrangement order of the associated media content corresponding to each candidate entity in the search, and the occurrence frequency of the same movie information in different associated media contents, to obtain sorting results of 'fan june-hua', 'love you nine weeks and a half', 'blue valentine' and 'love notebook', 'retroversion and retroversion', aggregating the identification information corresponding to each sorted entity and the related information corresponding to the entity information to generate a multiple entity aggregation result, and sending the multiple entity aggregation result to a user side, the user side can firstly display a plurality of target entities matched with the search request, and then display the search results related to the target entities based on the target entities of interest selected by the user.
