Research Of Educational Resources Construction And Retrieval Method

Educational resources are the important part of information resources in network, which are important on improving the quality of education and excavating the potential of education evolution. But nowadays, the actuality of educational resources construction is not satisfying, the confusion lead to heavily waste and repeating construction. In 2000, Ministry Of Education organized experts to constitute Technology Criterion On educational Resources Construction, from then the normative construction of educational resources became to an enthusiastic research. The purpose of educational resources construction is the farthest share and repeating using, but as the network information, the amount of educational resources is enormous, so we must provide convenient and efficient retrieval function for the resource database. Nowadays, the research on the technology of Chinese processing and retrieval have make great development, there have been appeared many retrieval facilities and a great deal of retrieval method. However, these facilities and methods are steal of much insufficiency. This study is to analyze and research from the sides such as the normative construction of educational resources, the design and realization on the management system of the resource database and the retrieval method for educational resource based on the fuzzy model. The central works are: 1. Analyzed the actuality of educational resources construction and current retrieval systems It expatiated on the background and signification of this study; analyzed the actuality of international research on the standardization of the educational information, and analyzed the research and application actuality of retrieval technologies in detail. At last, it discussed the trend of retrieval technology research. 2. Systemic constitution and functional design on standard resource database Firstly, it analyzed the content and direction of the Technology Criterion On Educational Resources Construction, secondly, it gave the material methods of construction of educational resource database based on the Technology Criterion. At last, it established a resource database system which functions include resource retrieval, resource accession and resource storage.
