Research On Construction Of Network-teaching Ontology And Its Semantic Retrieval

In the information age, network organization and management of teaching resources are the core competitiveness in universities, to extract user's information of necessary from a giant of data sets is a very important topic. Although we have rich teaching resources, there are still integration, standards, and practical issues. And in the research work of Web data extraction technology still have some difficult problems such as the data description, semantic accuracy, definite model. Therefore, the network standard, integration, storage, management, significance of teaching resources has become essential.In response to these problems, in basic of Web teaching's analysis and arrangement, according to the characteristics of network teaching and incremental process mining with new model update method to set up ontology; through experts in field and knowledge workers collecting and collating the ontology concept by Protege ontology tool to achieve the establishment of the field. The requirements of improving hardware and software environment and fast, accurate and efficient FTP; Web-based instruction based on the ontology construction, to achieve semantic network-based retrieval techniques of teaching.After analyzing the status of the network, the thesis expound the ontology of the theory, construction methods and search implementation in detail; refer to the relevant ontology construction methods and processes. We classified and arrange the network teaching, in basic of software engineering's incremental process mining with new model update method, to achieve the network teaching Ontology. Through relevant analysis and comparison of semantic search, ontology basically teaching the semantic network retrieval framework, design principles and implementation, detailed description of the design of the model and extraction Process.First of all, knowledge workers collect, classify and organize a network of teaching concept in this system by experts in the field of teaching the concept of the formation of the network set. According to methods based on the incremental model software for network step by step:curriculum resource ontology, course ontology and user ontology and the concept of relationship; online teaching through the realization of semantic retrieval ontology framework for analysis, design and implementation process of the formation description. By means of the application of ontology technology, the paper achieve the construction of network teaching and semantic search. incremental process mining with new model update method enriches the field of ontology construction, ontology network teaching online teaching resources to facilitate the extraction and the accuracy of information retrieval, user-friendly use of resources for online teaching to improve utilization of information resources, while for the full use of network teaching resources data provide an effective tool.
