Building the Core Vocabulary of Crop Names to Integrate the Vocabularies by Multiple Government Agencies

Since agriculture is the oldest industry in our society and the basis of our life and economics, knowledge of crops as product of agriculture is also old and spread all over the society. As a result, the names of crops are messy and sometimes inconsistent. It is problematic in the digital and Internet era since interoperability is not assured. In this paper, we proposes Crop Vocabulary (CVO) as the core vocabulary of crop names to solve interoperability and machine-readability on crop names. There are many vocabularies about crops by various food chain stakeholders. Here we picked up three vocabularies issued by Japanese government with respect to food security, namely the Agricultural chemical use reference, the Agricultural chemical residue reference, and the Food composition database, since food security is the primary concern of all food chain stakeholders including farmers and consumers. As the result of comparative analysis of these vocabularies, we defined the concept of crop as the botanical information such as the scientific name of species with additional information such as edible parts, cultivation methods and usage. According to the definition, we investigated these three vocabularies and identified 1,249 crops with unique names. The element of CVO contains the information about the crop itself such as synonym, English name and scientific name as well as links to names in the above-mentioned vocabularies and other external vocabularies such as Wikipedia, AGROVOC and NCBI Taxonomy. We develop web-based API for CVO and an application for the farm management as an example. The value of CVO as a core vocabulary in the field of agriculture is identified by compatibility with existing vocabularies and its usefulness is demonstrated by web services applications developed based on CVO.
