However, the corpus data that can be matched by this parallel structure method only matches the structure of the template in form, but not the relationship between the whole and the part in the actual content, so the extraction accuracy of this method is relatively low

Abstract

The invention discloses a term acquisition method and device, relates to the field of computer technology and mainly aims to improve the extraction accuracy of the whole and part relation between corpus terms through term annotation domain information. According to the main technical scheme, acquired text data is preprocessed to obtain independent sentences with segmented word information; a structure template is utilized to screen out candidate sentences with coordination structures among the independent sentences; a domain dictionary and the segmented word information in the candidate sentences are utilized to determine domain segmented words with coordination structures in the candidate sentences, wherein the domain dictionary records segmented words in the same domain; and a domain segmented word set with the whole and part relation is output according to positional characteristics of the domain segmented words. The term acquisition method and device are mainly used for acquiring the terms with the whole and part relation in texts.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for acquiring words. Background technique [0002] With the development of network technology, the scale of data information is getting larger and larger, and more effective text classification technology is needed to obtain useful data information. However, some existing mature text classification techniques are relatively ideal for English texts, but not ideal for Chinese texts. The reason is that the role of semantic factors in Chinese texts cannot be ignored. There are two types of the most basic semantic relations: 1. The relationship between superordinate concepts and subordinate concepts. The appearance of subordinate concepts is only to limit the extension of superordinate concepts; A statement of one basic lexical unit to another basic lexical unit. The grammatical forms are mostly produced to express these relations. [0003] Among the relation...
