Problems solved by technology

[0003] However, in the actual public opinion information system, a large number of events need to be monitored at the same time, which often involves massive text information, and the traditional manual participation method requires a lot of manpower and financial resources
In addition, public opinion analysts need a long cycle from collecting data to making a complete event tracking, which may easily lead to untimely and incomplete event tracking results

Embodiment Construction

[0033] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described with reference to the accompanying drawings.

[0034] According to one embodiment of the present invention, an event tracking method is provided. Briefly, the method includes: data acquisition, data preprocessing, determination of the number of event stages, document clustering, selection of representative documents, and normalized output.

[0035] now refer to figure 1 , each step of the event tracking method provided by the present invention is described in detail.

[0036] Step 1: Data Acquisition

[0037] To track an event, firstly all documents related to the event can be obtained through the network, that is, data collection. In one embodiment, obtaining all documents related to the event includes: performing a search on internal resources or external resources accor...

Abstract

The invention provides an event tracing method and system. The event tracing method and system are applicable to public opinion information processing. The event tracing method comprises the steps that files related to an event are obtained; the number of stages of the event is determined according to the number of the obtained files; the obtained files are clustered according to the level of similarity of content, and file clusters corresponding to the stages of the event respectively are obtained, wherein the total number of the file clusters is equal to the number of the stages of the event. According to the event tracing method and system, no manual intervention is needed, and event tracing and result output can be automatically carried out. Compared with manpower and financial resources consumed by manual arrangement, the cost is saved, and efficiency and accuracy of event tracing are improved.

Description

technical field [0001] The invention relates to the technical field of network information processing, in particular to an event tracking method and system suitable for public opinion information systems. Background technique [0002] In the process of public opinion information processing, event tracking is a very important link. Existing event tracking methods usually require a lot of manual participation, including: collecting a large amount of text information to determine the document list under a specific event; segmenting the collected document list to select various stages of the event; and , sorted by time to show a complete course of events. [0003] However, in the actual public opinion information system, a large number of events need to be monitored at the same time, which often involves massive text information, and the traditional manual participation method requires a lot of manpower and financial resources. In addition, public opinion analysts need a long ...
