A method and device for providing long tail search results

Abstract

The invention aims at providing a method and equipment used for providing long-tail search results. Particularly, the method comprises the steps as follows: obtaining long-tail description information corresponding to a candidate long-tail sequence according to the candidate long-tail sequence to obtain a corresponding candidate long-tail information record; creating or updating a long-tail information library according to the candidate long-tail information record; carrying out match query in the long-tail information library to obtain one or more long-tail search results corresponding to a target query sequence; and providing at least one of the one or more long-tail search results to a user corresponding to the target query sequence. Compared with the prior art, the long-tail information library is created or updated, and the match query operation is carried out in the long-tail information library according to the target query sequence to obtain the one or more long-tail search results corresponding to the target query sequence, so that the user demand satisfactory degree is increased and the information obtaining efficiency of the user is improved.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a technology for providing long-tail search results. Background technique [0002] At present, with the development of Internet technology and the penetration of Internet applications into users' study, work and life, more and more people obtain information through the Internet, such as entering long-tail words composed of multiple keywords in the search bar of search engines. Keywords to accurately express their needs, and then obtain corresponding search results, but for long-tail retrieval, such as when matching queries based on long-tail keywords, since long-tail keywords usually contain multiple words, search engines use keyword matching Common search results that match the long-tail keywords entered by users can be retrieved from the search index database, and long-tail sequences with different expressions but the same semantics cannot be identified, such as "how to bu...

Problems solved by technology

[0002] At present, with the development of Internet technology and the penetration of Internet applications into users' study, work and life, more and more people obtain information through the Internet, such as entering long-tail words composed of multiple keywords in the search bar of search engines. Keywords to accurately express their needs, and then obtain corresponding search results, but for long-tail retrieval, such as when matching queries based on long-tail keywords, since long-tail keywords usually contain multiple words, search engines use keyword matching Common search results that match the long-tail keywords entered by users can be retrieved from the search index database, and long-tail sequences with different expressions but the same semantics cannot be identified, such as "how to buy car insurance" and "how to buy car insurance"

Moreover, because the search volume of long-tail keywords is very small, the search results are unstable

Obviously, such ordinary search results often cannot well meet the user's long-tail retrieval needs, thereby reducing the efficiency of the user's information acquisition and affecting the user's search experience
