Abstract

Automatic construction of the thesaurus in the car patent field is an important semantic tool of car patent organization and retrieval. Not only the traditional method of constructing thesaurus is time-consuming and laborious, but also the speed of updating the thesaurus is slow. This paper puts forward equivalent relationship features weighting, correlative relationship features weighting and rank coefficient calculation three algorithms to respectively identify equivalent relationship, correlative relationship and hierarchical relationship, so as to achieve automatic construction of the thesaurus in the car patent field. This method brings new ideas to construct the thesaurus.
