Problems solved by technology

[0004] However, there may still be recognition errors in the entity word recognition results identified by existing entity recognition methods. In the prior art, it is impossible to judge the correctness and error of the entity word recognition results, resulting in poor recognition effect of entity words

Abstract

The embodiment of the invention provides an entity word recognition result evaluation method, device and equipment and an entity word extraction system. The method comprises: acquiring an entity wordrecognition result of a to-be-recognized document set, wherein the entity word recognition result is an entity word recognition result corresponding to any determined entity word recognition method byconducting entity word recognition on the to-be-recognized document set on the basis of at least one entity word recognition method; Determining a first weight of any to-be-evaluated entity word in the entity word recognition result corresponding to the at least one entity word recognition method in the to-be-recognized document set; And determining a second weight of any entity word to be evaluated based on the first weight of any entity word to be evaluated, the accuracy of the at least one entity word recognition method and the penalty coefficient of the at least one entity word recognition method, the second weight being used for evaluating any entity word to be evaluated. According to the scheme of the embodiment, the correctness of the entity word recognition result is judged through the second weight, and the entity word recognition effect is effectively improved.

Description

technical field [0001] The present application relates to the technical field of language processing. Specifically, the present application relates to a method, device, equipment, and entity word extraction system for evaluating entity word recognition results. Background technique [0002] With the popularity of the Internet and the rise of the mobile Internet, and the advent of the era of media and self-media, network content has increased dramatically. In a large number of event reports, we cannot read all the news reports at one time, and we cannot know the relevant people, places, and related institutions of the main event reports. This requires a system to extract the entity word information of the event and the entity word in real time. Evaluate weights to assist readers to predict the development and changes of events in advance. [0003] Entity recognition is an important research direction of natural language processing. Its purpose is to identify words representi...
