An Approach for Domain-Specific Mapping Metadata Terms to a Thesaurus Using LLM

Abstract

Some interoperable metadata terms have different roles from the labels of the terms themselves, depending on the domain in which the terms are used. However, it is not enough of vocabulary definition and relationship definition between terms, so it is difficult for metadata schema designers have less knowledge about metadata to find interoperable terms from the domain-specific words. We propose a method that maps interoperable metadata terms to thesaurus concepts that express the roles of the terms in the specific domain using LLM. We thought that we can link the metadata terms to the words that represent role of the terms by combining interoperable terms with domains that the terms are used in. Even without knowledge of the metadata, it is promising that the designers will find more interoperable terms by searching for the terms from the designers' words via the thesaurus.
