The purpose of the AOS is to achieve more interoperability between agricultural systems. Applying standards promoted through the AOS shall account for better indexing and retrieval of agricultural bibliographic resources. The goals of the Agricultural Ontology Service are realized by assisting community partners in building ontologies. An ontology (computer science) is a system that contains concepts, the definitions of those concepts, and the specification of relationships among those concepts. For those coming from the traditional library world, a thesaurus can be interpreted as a simple ontology, i.e. a conceptual hierarchy built by terms that are interlinked with few very generic relationships. An ontology goes beyond and defines and enables the creation of more formal, more specific and more powerful relationships as well as constraints and rules. An ontology captures and structures the knowledge in a domain, and by doing so captures the meaning of concepts that are specific to that domain. This meaning will then be available to end-users through the use of tools (e.g. indexing or search and retrieval applications) that apply the ontologies. ==Agriculture Ontology Service : Motivation== In the agricultural sector there exist already many well-established and authoritative controlled vocabularies, such as FAO's AGROVOC Thesaurus, the CAB Thesaurus, and the National Agricultural Library Thesaurus in the United States. However, for semantic tools to be entirely effective on the Internet, there is a need to re-assess the traditional "thesaurus" approach and move towards a more modern technique that better suits the Web environment, such as the development of "ontologies". Ontology in information management is a concept that has been emerging from the various Semantic Web initiatives. Roughly speaking, in the context of AOS, an ontology can be defined as a semantic knowledge organization system that contains concepts and their terms, the definitions of those concepts and terms, and the specification of relationships amongst them. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Agricultural Ontology Service」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
