Research On Knowledge Graph Construction Of Hui-style Architecture Based On Ontology

In recent years,with the rapid development of Internet technology and the rapid rise of information technology,the data in the Internet is increasing exponentially,and the sources of data are more diverse and the structure is more complex.In this context,the knowledge graph emerged.Compared with general knowledge graph,domain-specific knowledge graph has more prominent advantages in knowledge depth,knowledge integrity,data structure strictness and high reliability,and is mainly used for a variety of complex data-aided analysis and decision-making support in related fields.In the process of knowledge graph construction of specific domain,the knowledge graph construction method of ontology modeling is the most commonly used.Through the research and analysis of the knowledge in the field of Hui-style architecture,it is found that its forms are diverse and multi-source heterogeneous.Therefore,in order to effectively organize and manage the knowledge in the field of Hui-style architecture,realizing the protection and utilization of Hui-style architecture and the inheritance of Huizhou culture,based on the research and analysis of the knowledge graph construction technology,this thesis makes a deep research on the ontology modeling technology and knowledge reasoning method based on the construction of knowledge graph of Hui-style architecture.The specific work content as follows:(1)The method of constructing knowledge graph of Hui-style architecture.The knowledge graph is divided into pattern layer and concept layer.This thesis constructs the pattern layer of the knowledge graph of Hui-style architecture by using ontology modeling method.Through a detailed comparative study of the commonly used ontology construction methods,the "seven-step method" is improved,and the ontology evaluation standard of "skeleton method" is added.What is more,combined with the characteristics of knowledge in the domain of Hui-style architecture,the framework of knowledge ontology construction suitable for the domain of Hui-style architecture is proposed.First of all,through collecting and sorting out the knowledge of Hui-style architecture,the professional terms of Hui-style architecture are extracted,and the abstracted descriptions of the extracted terms are taken as the conceptual classes or instance attributes of the ontology of Hui-style architecture.The concept class is subdivided layer by layer by using the ontology modeling tool protégé to form the concept hierarchy structure of Hui-style architecture ontology.Then,the object attributes and data attributes of Hui-style architecture are defined,and the limited relationship between conceptual classes or instances in the ontology is constructed.Then,the consistency test is carried out on the constructed ontology to identify whether there is logical conflict between the attribute relations between conceptual classes.By importing the instance data of Hui-style architecture into the constructed ontology library,the construction of the knowledge graph data layer of Hui-style architecture is completed.Finally,the graph database Neo4 j is used to store and visualize the knowledge graph of Hui-style architecture is saved as a file in OWL format,and the knowledge graph of Hui-style architecture.(2)Hui-style architectural knowledge reasoning.In order to solve the problem of incomplete knowledge in the knowledge graph of Huistyle architecture,this thesis uses the knowledge reasoning method based on production rules to expand and complete the knowledge graph of Hui-style architecture.Based on the research and analysis of the characteristics of knowledge in the field of Hui-style architecture,this thesis constructs a set of rules for Hui-style architecture knowledge reasoning based on SWRL rule language.The inference task of deducting the unknown implicit information from the known knowledge of Hui-style architecture was completed by using the pattern matching algorithm of Jena inference machine,and the extension and completion of the initial knowledge graph of Hui-style architecture were realized.Finally,the operation process of inference module in inference engine is demonstrated through Hui-style architecture data example.Figure [36] table [16] reference [68]...
