Research on Semantic Information Retrieval Model of Bamboo Rattan Domain Based on Semantic Relevance

Abstract

At present, the research of semantic information retrieval technology is mostly in the initial stage, and the research is mostly in exploratory theoretical research. Among them, the construction of domain semantic information retrieval model is still immature. In this paper, bamboo rattan field was selected as the research object, and the key problems in semantic information retrieval technology of bamboo rattan domain were analyzed. Based on the domain ontology of bamboo and rattan, the weight calculation method of bamboo rattan domain terms is defined. This paper introduces semantic relevance degree extension into the domain semantic information retrieval model of bamboo rattan, constructs a domain semantic information retrieval model suitable for bamboo rattan, and realizes the association retrieval and semantic query extension of text information in bamboo rattan domain.
