提出基于语料库的概念相似度算法

并对计算机教育专业领域扩展主题图进行了融合实验.实验结果表明

TMMC提高了融合的准确率与查全率.

Abstract

Aiming at the distributed design and storage of topic map of domain ontology in abundance latent repetition

and redundancy in meanings and structures during merging process

a topic map merging algorithm(TMMC)based on common knowledge thesauri combined with corpus

is proposed

where the similarity of Chinese concepts in merging process is evaluated

then the hyponyms

part-of and other relations between concepts

are dealt with

and HowNet and the other thesauri are used to compose a multi-level similarity calculation during merging the concepts in ontology. The merging rules about the different semantic relationships among concepts are defined. For very large number of domain special terms are not included in the common knowledge thesauri

therefore a novel algorithm based corpus is presented for calculating similarities between domain special concepts. And the extended topic maps in computer specific education are tested to verify the improved F-measure value of TMMC.
