Abstract

The invention discloses an event extraction judgment method and system and belongs to the field of information processing. The method is characterized in that the method comprises the following steps of: obtaining natural linguistic data, and preprocessing the naturallinguistic datato obtain target linguistic data; based on the target linguistic data, performing event type judgment on the target linguistic data by using an algorithm library to obtain multiple groups of target type results; outputting an optimal type result based on the multiple groups of target type results; based on a named entity recognition and pattern matching algorithm, extracting a target event element of the target linguistic data, and judging the target event element; and based on the corresponding relationship between the optimal type result and the target event element, outputting an event extraction result. Through the algorithm library, the method has higher precision in event type extraction; meanwhile, the accuracy of event element extraction is improved through two-stage recall fine screening, and the algorithm precision of a whole event extraction task in a specific business scene is improved.

Description

technical field [0001] The invention relates to the field of information processing, in particular to an event extraction and judgment method and system. Background technique [0002] With the rapid development of the Internet, more and more information is presented to users in the form of electronic text. In order to help users quickly find the information they need in massive information, the concept of information extraction is proposed. Information extraction refers to extracting factual information from natural language texts and describing the information in a structured form. Event extraction is an important research direction in information extraction, which mainly refers to extracting event information of interest from text data containing event information, and expressing events in natural language in a structured form, such as, who, Where, when, and what was done, it can be seen that event extraction has extremely broad application prospects in today's massive i...
