Construction of a massive heterogeneous minority cultural resource integration model based on ontology

Abstract

At present, the sharing and dissemination of cultural resources of minorities in China remain at the early information service stage based on search engine and database query, with slow content updates, closed structure, independence from other databases, and disconnection of content, and they are far from meeting the actual needs of the sharing and dissemination of cultural resources of ethnic minorities. Therefore, aiming at the heterogeneity problem in the sharing and service of minority cultural resources and based on theories and methods such as domain ontology and Map Reduce, this paper first constructs a multi-source heterogeneous integrated model of massive minority cultural resources, Then, an example of Wa nationality is applied to construct the resource domain ontology of ethnic minorities and expand the domain. Finally, on the basis of semantic distance, a method of weighted comprehensive semantic similarity calculation is proposed and verified. The experimental results show that the similarity of the parent node and each child node in Wa hierarchical tree is different, and the similarity result is more reasonable than the original method.
