Research On Tourism Information Service Model Based On Linked Data

With the rapid development of online travel, travel information services provided through the Internet become increasingly richer. And users can meet diverse needs of tourist information through search engine and travel website. However, the growing number of travel information with different types, carriers, and storage modes has brought great challenges to the tourism organization and sharing of information. Currently, tourism information is mainly organized by the way of database. The internal closeness of database system and the heterogeneity of database make them difficult to reflect the relationship between tourism data, and integrate heterogeneous data. At the same time, E-R model of the database is also lack of tourist information semantic description, it is difficult to tap the potential of the semantic link relationship, thus affecting the quality of tourism information service.As a vision for the next generation of Internet, Web3.0 advocates the semantic description and storage of the resources on the Internet in the way that can be understandable and processable by the machine. The successful practice of linked data and related technologies brings new opportunities for the realization of the Semantic Web. The linked data emphasizes simple and efficient ways to describe and integrate information, then promotes the association and sharing of information, to eliminate the data island, realize the interconnection and reuse of information in the global space. The huge advantage of the linked data in the organization and sharing of resources provides a new way of thinking for the organization of tourism information, and also provides the basis of the construction of accurate and intelligent tourism information services.In this paper, the linked data and related technologies are introduced as the support, the organizations of tourism information and tourism information service model are discussed. First, this paper reviews the research status of the main research objects at home and abroad, and grasps the latest research trends. Secondly, in this paper, the related theories and key technologies of the related data are studied, and the organization method and service mode of tourism information are analyzed, which is the important theoretical basis of the tourism information service model based on the linked data. Thirdly, this paper puts forward the depth organization of tourism information using linked data, and gives the specific implementation method of tourism information organization based on the linked data. Fourthly, this paper puts forward the tourism information service model based on the linked data. The model includes data layer, organization layer, application layer and service layer. It describes the function and technical realization of each level in detail, and through the comparison of the full range of traditional tourism information services, the advantages of tourism information services based on linked data are displayed. Finally, this paper carries on the case analysis through the tourism linked data set Tourpedia, analyzes the construction process of tourism information service based on the linked data. Furthermore, the research verifies the feasibility of the tourism information service model based on the linked data proposed in this paper.
