Problems solved by technology

However, since any user can create content at will, the quality of information in the Q&A community varies greatly, so that there are a large number of low-quality Q&A pairs in the Q&A community.
This not only reduces the quality of the question-and-answer community, but also brings a lot of inconvenience to users in searching for information. The method of ranking search results, which relies more on the website to which the question-answer pair belongs and the non-textual characteristics of the question-answer pair to rank the question-answer pair, will affect the accuracy and generality

Abstract

The invention discloses a device and a method for optimizing search ranking of frequently asked question and answer pairs, which is used for optimizing the ranking of search results searched by the frequently asked question and answer pairs. The method comprises the following steps: receiving a search query of a user, and obtaining multiple frequently asked question and answer pairs to be analyzed matched with the search query according to the search query of the user; according to a question and answer knowledge base including multiple question and answer knowledge records, obtaining associated degree of each frequently asked question and answer pair to be analyzed; according to the associated degrees of the frequently asked question and answer pairs to be analyzed, optimizing the search ranking of the frequently asked question and answer pairs to be analyzed matched. The device and the method can evaluate the associated degrees of the frequently asked question and answer pairs to be analyzed as the search results and optimize the ranking of the search results, and the ranking effect is better.

Description

Technical field [0001] The invention relates to the field of network data communication, in particular to a device and method for optimizing the search ranking of question and answer pairs. Background technique [0002] The question-and-answer community is a network application in which users generate content. The basic form is that users ask questions according to their needs and other users give answers. This form provides a new channel for users to obtain information on the Internet. However, since any user can create content at will, the quality of information in the Q&A community is very different, so that a large number of low-quality Q&A pairs appear in the Q&A community. This not only reduces the quality of the Q&A community, but also brings a lot of inconvenience to users in finding information. For example, when using the existing search technology to perform a Q&A search, there are some low-quality Q&A pairs in the obtained search results. The method of sorting searc...
