[Abstract]:With the development of geographical information service application, more and more enterprises and organizations open their own geographical spatial data and software functions into geographical information services for people to use and effectively promote the sharing and functional multiplexing of geographical information, and also increases the number of geographic information services. Currently, users can only search and query OGC directory services through keyword search and spatial filtering conditions to discover the required data and services. Users benefit from the search for the resources brought by the directory service, and often suffer from the high check-up rate and the check-up rate. Facing the increasing service group, how to automatically, quickly and accurately discover the target service becomes the bottleneck affecting the further development and application of the geographic information service. In this paper, information retrieval technology, semantic web technology, semantic service technology, semantic annotation algorithm based on geographic concept matching, OWS service oriented to SOA framework and WSDL service description fusion strategy are introduced. The spatial semantic similarity measurement model based on the DL concept and the semantic matching and service discovery of the inclusion reasoning are deeply studied in four aspects. In this paper, some achievements have been made in the theoretical method and key technology of geographic information service based on semantic annotation, and the main work and innovation points are as follows: 1. The background, significance and related theory and technology of geographic information semantic service are analyzed Based on the problems existing in geographic information semantic service mode transition, geographic information service integration and sharing, the research progress of geographic information service based on semantic annotation is analyzed and analyzed. On the basis of this, it is pointed out that using semantic annotation technology to realize the semantic model of geographic information service is of great significance and extensive application The paper studies the base and key technology of geographic information service theory based on semantic annotation, and puts forward a semantic-oriented geographic information service framework and method system, and summarizes the matching and discovery of geographic information service based on semantic model. Method 2. In order to realize the multi-ontology dimension of the service, a three-tier architecture of geographic ontology oriented to service semantics is created, and the domain ontology and application ontology oriented to semantic annotation are developed by using the ontology engineering method, and a lightweight application ontology development is established. At the same time, based on the PageRank algorithm, the semantic annotation algorithm of the existing geographic information service is optimized with regard to the concept structure of the geographic ontology, the abstract model of the service semantic dimension and the annotation workflow are designed, and the automation degree of the semantic annotation is improved; On this basis, the strategy of OWS service and WSDL service description is proposed, which solves the problem of inconsistency between the two languages, establishes the WSDL mapping method of the OGC service conceptual model, and thus realizes the OGC and the WSDL service. The spatial semantic similarity measurement framework based on the concept of DL is designed, and the model of spatial semantic similarity measurement based on the DL concept is designed, and the model is validated. Based on the application requirements of the service semantic similarity measure, the research results on semantic similarity calculation are summarized, and the concept hierarchy spatial semantic similarity measurement framework is designed. Based on the framework, a space language for the DL concept description is put forward. In the end, the concept similarity test is designed, and the experimental results show that the ranking of the similarity of human similarity and the method of spatial semantic similarity measure are obtained. The result is highly correlated, and the spatial semantic similarity of this paper is verified. The feasibility of metric method is discussed. The inclusion reasoning mechanism based on spatial semantic similarity measure model is put forward, and the service semantic matching and discovery algorithm of mixed mode are established. firstly, a standard service discovery method implemented in the OGC directory is described, a detailed content of the OGC directory framework specification is provided, and the service discovery machine in the OGC directory is summarized. On the basis of this, a hybrid model service semantic matching algorithm based on the fusion similarity metric model and inclusion reasoning is proposed in order to solve the problems existing in the existing service discovery method. Meanwhile, the service semantic discovery engine and O are described. The integration model of the GC open source directory realizes the semantic query expansion of the query target definition and the service semantic matching algorithm based on the WSML, and provides the semantic directory. In this paper, a prototype system of geographic information intelligent service based on semantic annotation is constructed. The application experiment and verification of intelligent traffic dynamic information sharing service are carried out. The feasibility and practical value of technical method are established. The integrated experimental environment supporting service semantic annotation, service registration, semantic directory management, service matching and discovery is established, and its application in intelligent traffic dynamic information sharing service is explored. Portal open source portal platform has been developed by the service portal of the application experiment system. With the help of the OGC directory service semantic interface, the integrated publishing, semantic search, matching and discovery of road traffic information service are realized. In this paper, the dynamic publishing and sharing experiment of intelligent traffic flow information is carried out for traffic flow monitoring and application example, and the semantic mode based on semantic annotation technology is presented in this paper.
