Embodiment 1

[0027] Reference figure 1 , Shows a flowchart of the steps of a method for screening search results according to the first embodiment of the present invention.

[0028] The method for screening search results in this embodiment includes the following steps:

[0029] Step S102: Query the query words in the webpage database and the knowledge base respectively to obtain corresponding webpage documents and entity objects.

[0030] Among them, the webpage library stores webpage documents in the entire network, and the knowledge base stores entity objects in the entire network. The entity objects include entity names and corresponding entity attribute information. The entity attribute information includes entity category information and corresponding category-specific information. Attribute information, for example, entity category information includes "movie", but also includes: director, lead actor, release time and other "movie" category-specific attribute information.

Embodiment 2

[0043] Reference figure 2 , Shows a flowchart of the steps of a method for screening search results according to the second embodiment of the present invention.

[0044] The method for screening search results in this embodiment includes the following steps:

[0045] Step S202: Perform a first preprocessing on the query word to generate a query string including the keyword, so as to perform a web page database query according to the query string.

[0046] For example, perform preprocessing operations such as error correction, word segmentation, and word removal on the query to obtain one or more keywords, and then generate a query string containing the keywords. For example, when the user enters "Swordsman Huo Jianhua Version", after preprocessing operations such as error correction, word segmentation, and word removal are performed on the query, the keywords "Swordsman Huo" and "Huo Jianhua" are obtained. The query strings of "Swordsman" and "Huo Jianhua" can be used for subsequen...

Embodiment 3

[0077] Reference image 3 , Shows a structural block diagram of a search result screening device according to the third embodiment of the present invention.

[0078] The search result screening device of this embodiment includes: a query module 302, which is used to query query words in a webpage database and a knowledge base to obtain corresponding webpage documents and entity objects; wherein, the webpage database stores the entire web In the web page document in the knowledge base, the entity objects in the entire network are stored, and the entity objects include entity name and entity category information; the matching module 304 is used to associate and match each entity object with each page document; the determination module 306 , Which is used to mark each web page document whose matching degree meets the set matching rules according to the corresponding matching degree of each entity object in each web page document and mark it as the target page corresponding to the ent...

Abstract

The invention provides a search result screening method and a search result screening device. The search result screening method comprises the following steps of respectively querying query terms in a webpage library and a knowledge library and acquiring corresponding webpage files and entity objects; respectively performing relevant matching on the entity objects and the webpage files; respectively marking the webpage files of which the matching degree meets a set matching rule into objective pages corresponding to the entity objects according to corresponding matching degree of relevant matching of the entity objects in the corresponding webpage files; and screening the webpage files according to the marks, which correspond to the objective pages, of the entity objects so as to obtain the objective pages corresponding to the entity objects. The webpage files in a whole network are stored in the webpage library; and the entity objects in the whole network are stored in the knowledge library. By the search result screening method and the search result screening device, requirements on subdivision in the same industry category are met, and the information search efficiency is improved.

Description

Technical field [0001] The invention relates to the field of data processing, in particular to a method and device for screening search results. Background technique [0002] At present, when a user enters some ambiguous query words in a search engine, since the existing mainstream search engines are based on text matching methods, all possible results are returned to the user, and the top search results are often only Contains popular web documents. Take "Apple" as an example. Apple itself is the name of an objective entity. It may be a "company", it may be a "movie", or it may be a "fruit". When entering "Apple" in an existing search engine, these three types of web documents are often displayed in a predetermined order in the search results. For example, the first place displays the web documents corresponding to "Company" and the second place displays "Movies". Corresponding web documents, etc.; or mix different types of web documents together, and display them in a unified...
