| Abstract: | According to curriculum information architecture and realization of retrieval system, using a series of information science research methods such as document research, model conformation, compare analysis method, prototype conformation etc, this paper expatiates on the research process of curriculum semantic information extraction, storing, reasoning, retrieval and representation.The author collects and analyzes curriculum information, constructs ontology of curriculum knowledge, realizes information system with function of reasoning, retrieval and representation of curriculum ontology, semantic indexing with Lucene, stop words filtering with ICTCLAS, and visualizes curriculum ontology. |
