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

Embodiment Construction

[0057] Existing methods for obtaining search rankings for Q&A pairs use textual features and non-textual features to describe the questions and answers of Q&A pairs to rank Q&A pairs, or rank Q&A pairs according to the ranking of the websites to which the Q&A pairs belong. Text features mainly include text visual features (such as punctuation density, average word length, text entropy, etc.) and text content features (such as text content word ratio, interrogative word density, related word coverage, etc.), and extract Chinese automatic errors. Features (such as word density features, etc.); non-text features include user authority indicators, answer question status, answer answer time, user relationship interaction features, etc. After extracting the features of the questions and answers, a question quality prediction model and an answer quality prediction model are learned on the training set, and the output results of the two models are used to evaluate the quality of the qu...

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-answer pairs. Background technique [0002] A question-and-answer community is a network application that generates content by users. The basic form is that users ask questions according to their own 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 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. Methods for ranking search results, relying more on the website to which the question-answer pair belongs and the non-textual features of the question...
