[0243] Please refer to figure 1 , which is a flow chart of an embodiment of a method for determining an event category provided by the present application, and the executing body of the method includes an event category determining device. A method for determining event categories provided by this application includes:

[0244] Step S101: Obtain the event text to be classified.

[0245] The event text to be classified describes an event and is text related to the event. For example, the event text can be the case files of illegal cases, the announcement of mergers and acquisitions of automobile companies, the report of equipment failure in electric power companies, and so on.

[0246] For example, the text of the event to be classified is an indictment, and the description of the indictment is "1. I cooperated with my friend on a project worth 3 million, and we verbally agreed that after the end of the project, both parties will share 50% of the project profit equally, but t...

Abstract

The invention discloses an event category determination method and device, a traffic information broadcasting system, method and device, and electronic equipment. The event category determination method comprises the steps of obtaining a to-be-classified event text; for words included in the text, determining a sub-network through word vectors included in an event classification model, and determining second word vectors, including semantic information and event element type information, of the words according to the first word vectors of the words; through an event feature extraction sub-network included in an event classification model, according to the second word vector, extracting event features including text semantic information and event element type information; and determining an event category of the event text according to the event features through an event category prediction sub-network included in an event classification model. By adopting the processing mode, the semantic information of the event text and the event element type information of the event text are combined to carry out event type recognition; therefore, the accuracy of event category recognition can be effectively improved.

Description
