Abstract

The invention aims to provide a method and equipment for extracting entity information of an emergency. Compared with the prior art, the method has the advantages that the emergency information used for extracting the entity information is determined, then the candidate entity information in the emergency information is extracted, and the candidate entity information comprises one or more pieces of event element information used for describing the emergency information; and content relationship identification is conducted on the candidate entity information and the emergency information, and the candidate entity information meeting a content relationship identification threshold is determined as the entity information of the emergency. In the way, the entity information in the emergency information can be extracted conveniently and quickly, and the efficiency is improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a technology for extracting entity information of emergencies. Background technique [0002] In the prior art, event extraction refers to extracting event information of interest to the user from natural language text and presenting it in a structured form, such as who / organization, when, where, what happened What matters, this information can be called the entity information of the event. The prior art solutions for event extraction mainly include: 1) pattern matching method, which mainly designs templates according to language patterns, and matches sentences to be extracted with existing templates. Usually based on syntax trees or regular expressions; 2) Pipeline / pipeline-based machine learning methods, mainly by converting tasks into multi-stage classification tasks; 3) Machine learning methods based on joint construction models, mainly by converting tasks into T...
