Domain Top-Level Ontology Research:Model and Construction Method
[Research purpose]Currently,ontology research in various fields faces significant difficulties in association and reference re-use.Building a domain top-level ontology aims to scientifically define it in terms of structure and terminology,thereby promoting the standardization and normalization of ontology and knowledge service work in the field.[Research method]The article designs a domain top-level ontology model by sorting out the construction ideas of general ontology.Then,taking the field of crops as an example,a sys-tematic method for constructing top-level ontology in the field is proposed,and a top-level ontology in the field of crops is constructed.Finally,the effectiveness of the top-level ontology in guiding the construction of domain knowledge ontology is verified through the rice domain ontology constructed.[Research conclusion]The empirical results indicate that the proposed domain top-level ontology model can provide a more efficient construction method path for domain ontology research work through its universal classification ideas and au-thoritative terminology,and can provide standardized and normalized guidance for ontology research and knowledge service work.
