Abstract


With the rapid development and widespread popularity of computer network, the network of information resources is growing. Similarly, digital library information resources was also a geometric growth, people are drowning in the ocean of information resources, and take full advantage of the information resources are extensive attention. Web3.0 Web1.0 and Web2.0 inheritance and development of Web3.0 development of the use of the computer to the semantic level identified by the computer is no longer a simple bunch of character logos and character handling, better able to understand the semantics contained in the character, information resources sharing, and thus more conducive to easy for people to communicate with the computer, so that the man-machine dialogue and work together. This paper first introduces Web3.0 and its related concepts, on this basis, the analysis Web3.0 used the concept of the Semantic Web and its related technology, combined with the concept of graph theory applied to the digital library build a model based on Web3.0 digital library of personalized information services platform framework. This paper, the work carried out as follows: (1) introduced the concept of the Web and its development process and the research status quo, discusses the development of Web1.0, Web2.0 and Web3.0 and their respective characteristics and three The comparative analysis, to explore the Web3.0 advantages and inadequacies in the development process and its use in digital libraries. (2) the Semantic Web concept and its hierarchical structure and the related research work. Focuses on the key technology ---- Ontology of the Semantic Web, and discusses the ontology definition and its modeling method, a detailed study of the definition and application of ontology description language OWL, the OWL language to describe the body of knowledge. (3) The definition of the concept map and its related technologies. Discusses the concept of knowledge representation and logic reasoning process, the body of knowledge through the conceptual diagram form and concept map node similarity relations similarity algorithm to draw a concept map similarity in order to achieve the semantic similarity search of the body of knowledge. (4) Construction of a model based on Web3.0 digital library of personalized information services platform framework. Semantic Web technology and the concept of graph theory is applied to a digital library, build a Semantic Web-based digital library personalization platform model, the model by the personalization module information resource integration processing module, semantic analysis and processing module, query module IV components and specific analysis of the function of each module.
