Research On Ontology Construction And Intelligent Applications Of Tang Poetry For Domain Knowledge Service

The development of the new generation of artificial intelligence technology represented by knowledge graph has brought new ideas and new methods to the research of Digital Humanities in Tang poetry.Using knowledge graph to provide intelligent knowledge services has become a new direction in the field of Digital Humanities in Tang poetry.At the same time,with the growth of big data of Tang poetry,knowledge services requirements in the field of Tang poetry have changed from traditional information query to accurate,professional and intelligent knowledge services,which puts forward new demands for fine-grained and semantic knowledge organization and representation of Tang poetry.However,the current knowledge organization of Tang poetry on the Internet is loose and sparse,complex and heterogeneous,which greatly increases the difficulty of knowledge acquisition,organization and utilization.As a clear and formal semantic description model of domain sharing concept,domain ontology can effectively organize and represent the concepts,terms,attributes,relationships,etc.in the knowledge of Tang poetry,which becomes the basis of knowledge graph construction and domain knowledge services.Therefore,based on the knowledge service requirements in the field of Tang poetry,this paper constructs Tang poetry ontology oriented to domain knowledge service,and realizes intelligent applications of ontology in the context of knowledge graph.First of all,this paper uses three qualitative and quantitative methods: expert consultation,questionnaire and knowledge group to investigate knowledge services requirements in Tang poetry field;The research targets include three types of users including scientific researchers,ordinary users and developers;And by analyzing the collected requirements,this paper constructs a requirement analysis framework for Tang poetry ontology construction,thus forming a prior prototype of the construction of Tang poetry ontology.So that domain ontology can cover complex and changing knowledge service requirements,forming a prior prototype of Tang poetry ontology.Secondly,this paper proposes a building framework model of Tang Poetry Ontology for Domain Knowledge Service(TPO4DKS),including distributed heterogeneous data source layer,ontology pattern layer and ontology intelligent applications layer.Based on this construction framework,this paper further proposes a methodology of TPO4 DKS,including four steps: normalization,conceptualization,formalization and integration,which are gradually constructed according to the ontology hierarchy of meta ontology—subdomain ontology—global ontology;Meanwhile,this paper uses the OWL language and Protégé tools to edit and manage TPO4 DKS model,and uses the Virtuoso database to store TPO4 DKS model in the form of RDF triples in ontology knowledge base.Finally,this paper studies intelligent applications research based on TPO4 DKS,including supporting knowledge management,knowledge reasoning and knowledge query.Among them,TPO4 DKS based knowledge management supports the recognition,extraction and storage of Tang poetry knowledge through semantic annotation,semantic integration and knowledge storage;Knowledge reasoning realizes knowledge reasoning applications in Tang poetry by constructing reasoning rules based on OWL language,production rules and custom SWRL rules;For knowledge query,the SPARQL query function based on the ontology knowledge base continuously improves the ontology model layer to make up semantic gaps between knowledge base and query requirements,thereby enhancing service capability of knowledge query.
