Embodiment Construction

[0038] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary only, and are not intended to limit the scope of the present invention. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concept of the present invention.

[0039] Effective data mining based on network news and using historical information to predict the development trend of future events is a work with great practical application value. Existing methods are generally artificially predicted by domain experts based on their experience, which is highly subjective and inconsistent. Easy to get consensus, uncertain reliability and other shortcomings. Based on historical news ...

Abstract

The invention relates to a historical news report-based event trend prediction method, which comprises the following steps of: firstly, determining a to-be-predicted new event field, and acquiring similar events based on a public data set or data acquired by a network; in each similar event, news describing the same specific event is clustered into a sub-event, and distribution information of subsequent events of each sub-event is obtained according to relevance and time sequence of event contents; calculating the similarity between the similar events and the to-be-predicted new events to obtain similar events; according to the method, the current sub-event and the sub-event in the similar event are subjected to data processing, the similarity between the current sub-event and the sub-event in the similar event is obtained by calculating the similarity in the similar event, and the development trend of the current sub-event is predicted according to the two similarities and the event distribution information. Various possibilities of future event development can be comprehensively and quantitatively given, and related personnel can perform analysis and prediction in an uncertain scene.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a method for predicting event trends based on historical news reports. Background technique [0002] With the development of the Internet, a large amount of news is reported in the form of network text. Efficient mining of network news is an important demand for economic and social development. Among them, predicting the future trend of a certain news event is an important and useful method. It is a very difficult problem with huge economic and social value. Existing methods are usually inferred by domain experts based on their own experience to predict the development of subsequent events. However, due to the different backgrounds and inconsistencies of each person's views, the prediction results often have large differences, and the accuracy rate cannot be guaranteed. [0003] Humans’ prediction of event development is usually based on the accumulation of personal knowledge a...
