Abstract
This research was aimed at constructing a thesaurus of the ethnic groups in the Mekong River Basin that is a compilation of controlled vocabularies of both Thai and English language, with a digital platform that enables semantic search and linked open data. The research method involved four steps: (1) organization of knowledge content; (2) construction of the thesaurus; (3) development of a digital thesaurus platform; and (4) evaluation. The concepts and theories used in the research comprised knowledge organization, thesaurus construction, digital platform development, and system evaluation. The tool for developing the digital thesaurus was the Tematres web application. The research results are: (1) there are 4273 principle words related to the ethnic groups that have been compiled and classified by the terms for each of the eight deep levels, 2596 were found to have hierarchical relationships, and 6858 had associative relationships; (2) the digital thesaurus platform was able to manage the controlled vocabularies related to the Mekong ethnic groups by storing both Thai and English vocabularies. When retrieved, the vocabulary, details of the broader term, narrow term, related term, cross reference, and scope note are displayed. Thus, semantic search is viable through applications, linked open data technology, and web services.
Highlights
The term ‘ethnic group’ is generally understood in the humanities as a social group or a category of the population who cluster together as part of a bigger society, which can be a community, a country, or a region
Data resources for the analysis: The information related to the ethnic groups in the Mekong River Basin was compiled from various sources, namely: (1) the domestic and international databases of information resources, in which a lot of collections exist in the fields of humanities and socio-cultural aspects of the Mekong River Basin, the research emphasized the studies conducted in Thai and English; (2) the information corpus or international databases, in which cultural vocabularies have been collected: Yale University
This research is the continuation of former work [22,23,24], which organized knowledge and constructed the channel for exchanging information on the ethnic groups in Thailand in the form of ontology taxonomy and linked open data
Summary
The term ‘ethnic group’ is generally understood in the humanities as a social group or a category of the population who cluster together as part of a bigger society, which can be a community, a country, or a region. The members of an ethnic group have lifestyles and social activities that differ from one area to another, which depend on the government’s policy, the environment, and socio-economic development carried out in their domicile [1,2,3,4]. It can be said that an ethnic group is the population that has become part of a bigger multi-cultural society. The cultural multiplicity and differences of ethnic groups are significant elements when setting national development strategies [5,6]
