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.

Description

technical field [0001] The invention relates to the field of knowledge engineering, in particular to a method for constructing a knowledge base oriented to ancient texts of traditional Chinese medicine. Background technique [0002] Traditional Chinese medicine is a discipline with a long history. Some theoretical knowledge, experience and medical records of ancient medical masters have been recorded in the form of classical Chinese and have been handed down to this day. However, these ancient texts of traditional Chinese medicine are all in the form of classical Chinese and are unstructured texts. Moreover, the content of ancient Chinese texts is huge and complex, and there is no unified structural understanding. The content of the demand. Therefore, how to sort out and utilize the massive knowledge contained in ancient Chinese medicine has become a hot issue in the field of Chinese medicine. [0003] The knowledge base is a structured, easy-to-operate, easy-to-use, and c...
