Automatic extraction method and system for triggering words of events in field of traditional Chinese medicine acupuncture and moxibustion

Abstract

The invention provides an automatic extraction method and system for triggering words of events in the field of traditional Chinese medicine acupuncture and moxibustion. The method comprises the steps of firstly manually predefining a traditional Chinese medicine acupuncture and moxibustion event template and establishing a tagged corpus library of traditional Chinese medicine acupuncture and moxibustion events; designing an initial triggering word table establishment method for establishing an initial triggering word table of the traditional Chinese medicine acupuncture and moxibustion events according to the tagged corpus library; designing a triggering word expansion algorithm for expanding the initial triggering word table; designing a candidate triggering word extraction algorithm for extracting triggering words of candidate acupuncture and moxibustion events based on the expanded triggering word table of the traditional Chinese medicine acupuncture and moxibustion events; designing a triggering word filtering rule for filtering the triggering words of the candidate acupuncture and moxibustion events; and building a triggering word automatic extraction model by the initial triggering word table establishment method, the triggering word expansion algorithm, the candidate triggering word extraction algorithm and the triggering word filtering rule, thereby realizing automatic extraction of the triggering words of the events in the field of the traditional Chinese medicine acupuncture and moxibustion.

Description

technical field [0001] The invention relates to a method and tool for extracting information in the field of acupuncture and moxibustion of traditional Chinese medicine (ie Chinese medicine), in particular to a method and system for extracting event trigger words in the field of acupuncture and moxibustion of traditional Chinese medicine. Background technique [0002] event extraction [1 - 2] It is a high-level information extraction research task, and its purpose is to automatically identify event information that people are interested in from massive data texts, and convert this information into structured data for presentation. Event trigger word recognition is the recognition of event categories, which plays a key role in the event extraction task. There are three main methods of mainstream event trigger word extraction: rule-based method [3 - 5] , method based on dictionary matching [6-8] and machine learning based methods [9-12] . [0003] The rule-based method ...

Problems solved by technology

However, due to the linguistic characteristics of Chinese and the frequent occurrence of single-character words and idioms in texts in the field of acupuncture and moxibustion of traditional Chinese medicine, such as: "moxibustion", "thorn", "resistance", "soothing the liver and regulating qi", " dredging the meridian and activating collaterals", etc., It hinders the application of event extraction technology research achievements in the field of English biomedicine and Chinese general field in the field of event extraction in the field of acupuncture and moxibustion of traditional Chinese medicine

So far, no event information extraction system in the field of acupuncture and moxibustion of traditional Chinese medicine has been released, and relevant research papers on event extraction technology in the field of acupuncture and moxibustion of traditional Chinese medicine are rarely reported
