Method and device for generating searching result

Abstract

The invention provides a method and a device for generating a searching result. The method comprises the following steps of S1, using an anchor text of a webpage or a click text of a user in advance to obtain a lexical item of each website and the weight of each lexical item, and establishing the website model of each website; S2, acquiring a search term of the user, and obtaining each matched webpage matched with the search term through retrieval; S3, obtaining the domain relevance between the search term and the website corresponding to each matched webpage through correlation calculation by using the search term and the website model established in the step S1; and S4, according to the domain relevance between the search term and the website corresponding to each matched webpage, sequencing each matched webpage to generate the searching result. Compared with the prior art, the method has the advantages that the domain relevance sequencing of the searching result can be improved, the user is facilitated to quickly find the searching result, meanwhile, the efficiencies of the user and a system are improved, the interaction times are reduced, and the burden of a server is mitigated.

Description

【Technical field】 [0001] The invention relates to the technical field of Internet applications, in particular to a method and device for generating search results. 【Background technique】 [0002] With the continuous development of information and network technology, search engines have become an important way for people to obtain information. By inputting a search term (query) in the search engine, the user obtains the search result returned by the search engine for the search term. Search results are usually obtained according to a series of scoring strategies and sorting algorithms. Among them, in addition to keyword factors, the main factor that affects the ranking of search results is the authority of the site (website). [0003] The existing authority mainly considers objective factors such as the hyperlink relationship of web pages, the degree of access of Internet users, and the authority level of the site itself. This way of using hyperlinks and other relationship...

Problems solved by technology

This way of using hyperlinks and other relationships to measure the authority of websites / URLs usually reflects popularity, which generally only reflects the popularity of webpages on the entire Internet. However, for some non-Internet mainstream or traditional industries, their Internet-based The degree is not high, such as oil sites, professional dance sites, poetry sites and other sites that are only popular in the professional field. The authority of these sites in the same field should actually be very high, but the existing methods are not true reflect its authority

This will lead to some globally authoritative webpages ranking too high, while well-known webpages in this field will be squeezed

For example, if you search for "the first lesson of elementary school Chinese", educational sites should rank relatively high, but according to the existing methods, there are often cases where document, video, and blog sites have high results; therefore, the current authoritative The authoritativeness of the site is mainly measured by the popularity of hyperlinks, etc.; the lack of domain expertise to measure the authority of the site leads to poor correlation of search results and makes it difficult for users to find the results they want, especially for niche and popular majors. site, which will inevitably increase the number of interactions between the user and the system, causing greater pressure on the server
