Construction method of knowledge base for ancient Chinese writings about traditional Chinese medicine

Abstract

The invention provides a construction method of a knowledge base for ancient Chinese writings about traditional Chinese medicine. With the method adopted, the knowledge base for ancient Chinese writings about the traditional Chinese medicine can be quickly built, and time and effort can be saved. The method includes the following steps that: keywords are extracted from a traditional Chinese medicine ancient writing corpus, entities of which the word frequencies are greater than a preset word frequency threshold are obtained, and a seed entity word list is formed; sentences with two or more entities are screened out from the traditional Chinese medicine ancient writing corpus according to the seed entity word list, verb relations between the entities are obtained by means of syntactic analysis, and a seed verb word list is formed; and the seed entity word list is expanded according to the seed verb word list; the steps for forming the seed verb word list and expanding the seed entity word list are iteratively performed until new entities and verbs cannot be acquired, and entity relation triples are obtained; hierarchical clustering is performed according to the obtained seed entityword list, a classified entity word list is obtained, the obtained entity relation triples are used in combination, so that the knowledge base for the ancient Chinese writings about the traditional Chinese medicine can be constructed.
