Research On Construction And Storage Methods Of Smart Home Domain Ontology Model

With the rapid development of internet technology and artificial intelligencetechniques, especially in recent years, intelligent control technology and computernetwork technology is widely used in the home. Smart appliances and smart networkdevices have appeared more and more, and people have become increasinglyintelligent and humane requirements in the field of home appliances, equipment andcontrol systems.Therefore, how the family in a variety of intelligent devices andresources for effective management and knowledge sharing is a hot field of homeproblems. While many home appliance enterprises launched many different smarthome management system for the needs of people, because each manufacturer usesdifferent technical standards and norms, and the existing home management systemsare not a good solution for a variety of resources in the field of home effectivemanagement of knowledge sharing issues.Based on the above analysis, in order to improve effectively organize andmanage a variety of information resources the field of intelligent home, and solveproblems of efficiently query semantic information in the field of home. This articleuses the basic knowledge ontology, reference existing domain ontology constructionmethod, after the analysis to the resources and relationships in the field of intelligenthome, building a generic model of smart home domain ontology. In order to achieveknowledge sharing and the actual use value of household ontology model, this articlefocus on the manner in which the ontology persisted to the database. After carefulstudy and analysis of existing ontology storage media and related ontology storagemethods, the paper decided to use relational database to complete home ontologydata storage.Through the current analysis and comparison of several storage mode based onrelational database, found that each one has a large storage limitations. In order to achieve efficient storage and use of home ontology data, on the basis of the furtherstudy of the existing ontology storage method, combining with the characteristics ofbasic knowledge in the field of smart home, this paper proposes a transformationway from the ontology model to relational model. The conversion mode is based onsummarized conversion principle. First, in order to improve the efficiency of thequery semantics, the most common ontology metadata and relationships were builttable separately. And then not commonly used elements of ontology are built tablealone, so it can ensure complete semantic information. This paper presents the testprogram for the performance verification of new storage model, Test data show thatthe proposed model from ontology structure to the relational structure is not onlystructurally stable, easy to understand, and with increasing body size, still has a highquery efficiency.The innovation of this paper is to use the concept of the ontology to unifymanagement of resources and equipment of smart home field. Information andresources of smart home field are analyzed and extracted from the perspective of thesemantic ontology, established a good scalability and versatility ontology model. Onthe basis of the study of the limitations of existing ontology storage method,designed a better storage way based on relational database for the establishedontology model. Providing a good sharing foundation and efficient semantic querybasis for the actual use of home field ontology model.
