Research on Adaptive Information Retrieval of Educational Resource Library Based on Web Knowledge Discovery

Abstract

Abstract. Based on the collaborative thinking of the digital campus information system using two design ideas, embodied in the collaborative matrix model and gear interaction model. Through these design ideas, you can integrate a variety of applications and information together, so as to achieve a smooth flow between each other and coordinated management. ForewordNetwork teaching resources are the prerequisite and basis for carrying out network education. With the development of Web technology and network information technology, the network teaching resources are becoming more and more abundant, and the variety of forms is rich, which provides a wide range of choices and broad development space for learners' learning. Web has become a public application platform, the diversification of Web resources, the autonomy of knowledge learning and the sharing of resources and learning virtualization has become a major advantage of today's online learning. Semantic Modeling in System ConstructionThe semi-structured and structured fuzzy features of Web resources are typical features of Web resources. In the process of managing Web resources, due to the existence of resource structure differences, the traditional relationship model between Web resources cannot meet the modeling requirements of Web resources. Therefore, in the construction of semantic Web for college professional curriculum teaching resource library system, it also requires the model must be defined in a clear semantics. In general, the extent to which metadata can be described in terms of resource-related context knowledge is a measure of the semantic description of metadata [2] . Therefore, it is the key to the design of semantic metadata to describe the domain resources, to determine the appropriate metadata vocabulary, and the relationship between them. In addition, the ontology, especially the descriptive ontology, provides the basis for the design, extraction and generation of semantic metadata, because the ontology is a conceptualization of domain knowledge, which describes the concept and the semantic relations between concepts. Ontology Description of the Knowledge of Subject Curriculum ResourcesAccording to the C # professional workflow and the typical task of knowledge is based on the skeleton of the flesh and blood, the body is the skeleton of the knowledge base. In other words, the subject knowledge base is the body's blood, the body is the subject of the professional knowledge base. The main purpose of the ontology is to provide a number of applications and users can use the method to understand the areas involved in the knowledge and concepts, so as to achieve the purpose of reusing resources. The knowledge ontology is the conceptual model of knowledge that constructs the most important ontologies of the knowledge base and is stored in the nodes of the knowledge base. It is usually described by class and attributes 352
