Problems solved by technology

At present, the network-based credible propagation algorithm is mainly used in fraud detection, high-quality comment content screening, authoritative user and trusted user discovery, etc., and no research has proposed using the network structure to complete the modeling of various factors that affect the credibility of the answer. Through Trusted Inference Algorithms on the Web to Evaluate Answer Believability in an Unsupervised Way

Embodiment Construction

[0061] The present invention is described in further detail below in conjunction with accompanying drawing:

[0062] refer to figure 1 , the network-based community question-and-answer website answer credible evaluation method of the present invention comprises the following steps:

[0063] 1) Build an answer-user association network;

[0064] 2) Based on the construction of the answer-user association network, the mutual inference algorithm is used to obtain user credibility and answer credibility in an iterative manner.

[0065] The specific operation of step 1) is: construct the answer-user association network G, where,

[0066] G={V,E,W,P}

[0067] Among them, V represents all nodes in the answer-user association network, E represents all edges in the answer-user association network, W represents the weight on the edge, and P represents the prior credibility of the node.

[0068] V=A∪U, is the set of answers under all questions, U={u 1 , u 2 ,... u k} is the set o...

Abstract

The invention discloses a community question and answer website credible evaluation method based on a network, comprising the following steps: 1) constructing an answer-user association network; 2) based on the construction of the answer-user association network, using the mutual inference algorithm to acquire the user credibility and the credibility of the answer in an iterative manner., and themethod can evaluate the credibility of the answer of the community question answering website.

Description

technical field [0001] The invention relates to a method for assessing credibility of answers, in particular to a method for assessing credibility of answers on a network-based community question-and-answer website. Background technique [0002] In today's information explosion, community question-and-answer websites provide a way for people to get answers quickly. On the community question-and-answer website, users can ask and answer questions in natural language, and at the same time, they can express their support or disapproval by performing operations such as likes and comments on questions and answers. Compared with traditional retrieval and query methods, users can express their information needs more accurately and directly on community question-and-answer websites, and ask some complex, open, reasoning and suggestion-type questions, while based on user-generated content (UGC) The answer can provide users with information that they cannot directly obtain from encycl...
