Research On The Method Of Evaluating The Spreading Range Of Weibo Released In The Early Stage

The rumors spread on the Weibo across the region and quickly,damaging people's mental health and undermining the cyberspace order.In order to reduce the negative consequences of Weibo rumors,it is necessary to find rumors that may spread widely in the future in the early stage of news,so rumors are detected in the early stage of the news release and the scope of the rumor is pre-evaluated.Firstly,the early detection model of Weibo rumors was constructed,and rumors were detected for a single message at the time of message release.Because rumors have stronger communication requirements than non-rumors,the guiding words are proposed,and the content-based features,publisher-based features and guiding word feature are extracted from a single message at the time of message issuance for early rumor detection.The experimental results show that the newly proposed guiding words can effectively improve the detection effect of rumors,and the early rumor detection model can reach a better level.Secondly,there are false positives and false negatives in early rumors detection models.If the rumors directly detected by the model are punishable,the user experience will be affected.Therefore,the rumor spread scope evaluation model is proposed,and the rumors that may be widely spread after the release are sought in the early stage of the rumor release to help the official to verify the rumors in a timely and focused manner.The evaluation cycle is set in the model,and the user's historical data such as relationship data and forwarding relationship data are used to improve the user influence algorithm.The comprehensive influence of the rumor publisher is used to pre-evaluate the possible range of rumors that may eventually be reached.Finally,screen out rumors that may be widely disseminated after the release to help the authorities verify the rumors in a timely and focused manner.The experimental results show that the rumor propagation range assessment model can effectively pre-evaluate the range of rumors that may be reached in the future,and find rumors that may cause a greater impact after a certain period of release.Combined with the early detection model of Weibo rumors and the rumor spread scope assessment model to find rumors that may be widely disseminated in the future,it provides guarantee for Weibo officials to effectively control rumors in the early stage of rumors.
