The current social network has replaced traditional media as an important platform for information exchange. The information in social networks has the advantages of fast dissemination
wide range
and strong immediacy. However
due to the lack of effective supervision means when publishing information
the social network platform has also become a hotbed of rumors. Therefore
the rapid and effective detection of social network rumors is essential for purifying the network environment and maintaining public safety. Firstly
this article explains the definition of rumors
and the problems of current rumors detection and detection process are described. Secondly
different data acquisition methods are introduced and their advantages and disadvantages are analyzed. At the same time
different data annotation methods in rumor detection are compared. Thirdly
according to the development of rumor detection technology
analyze and compare the existing rumors detection methods of artificial
machine learning and deep learning. Fourthly
current mainstream algorithms are empirically evaluated under the same open data set through experiments. Finally
analyze and summarize the challenges faced by current social network rumor detection technology.
