Evidence theory based Chinese microblog credibility evaluation method

Abstract

The invention belongs to the field of information retrieval and evaluation and particularly relates to an evidence theory based Chinese microblog credibility evaluation method. Started with intrinsic characteristics of Chinese microblogs, a multidimensional evidence based microblog credibility evaluation method used for integrating three heterogeneous dimensions is provided after measurability and practical tasks of the intrinsic characteristics are taken into account, credibility measuring indexes of Chinese microblog information are systematically ordered and are classified into three high-level dimensions including text information, information sources and information dissemination. Compared with an evaluation method for a single characteristic of web texts or interconnection relation in the prior art, the evidence theory based Chinese microblog credibility evaluation method is more comprehensive and reasonable, is capable of preferring to reliable sources and spreading information widely under the same query condition.

Description

Technical field [0001] The credibility evaluation method of Chinese Weibo based on evidence theory belongs to the field of information retrieval and evaluation. Background technique [0002] In recent years, social media has developed rapidly, especially Weibo, such as Twitter in the United States, Sina Weibo in China, and Tencent Weibo, which have developed into giants on the Internet. According to the "The 30th Statistical Report on China's Internet Development Status" released by the China Internet Network Information Center (CNNIC) in July 2012, as of the end of June 2012, the number of Weibo users in my country reached 274 million, and the penetration rate of Weibo has More than half, and the growth rate of Weibo on mobile phones is still obvious, with a growth rate of 24.2%. According to the results of the “Survey on the Usage Rate of Social Media” completed by the Chinese Internet Survey Community (http: / / h.cnnicresearch.cn / sv / result / sid / 22253) on January 13, 2013, Weibo (...

Problems solved by technology

[0004] Due to the time factor, most of the current research examples on microblog quality focus on Twitter analysis. These studies can be divided into two categories. One is qualitative analysis using traditional classification techniques. This type of research requires a large number of samples. Numerical conclusions of right and wrong cannot be used for quantitative evaluation; the other type is some quantitative algorithms for different performance indicators, but most of the existing quality evaluation functions only focus on the information itself or a certain aspect, lacking systematic and comprehensive analysis and evaluation, let alone Measuring from the perspective of fuzzy cognition

At present, most studies on the quality analysis of Chinese microblogs focus on content analysis and specific topic extraction, and there is a lack of systematic methods for quantitative evaluation of quality.
