Abstract


With the development of computer and network technologies , E - learning learning environment gained popularity at the same time the various network teaching platform , such as LMS also came into being . Resource search is one of the functions of the LMS , can find the resources needed to facilitate the teaching and learners from the network platform , has greatly improved the efficiency of teaching . Today 's search technology almost all use the keyword literal matching - based approach , the search results are often not reflect the original intent of the searcher , may get a lot of irrelevant information , or missed many of the relevant information . The emergence of the Semantic Web as a way to solve this problem , by adding semantic information resources on the World Wide Web , so that computers understand and process the resource information to search vast amounts of resources . By semantic-based search allows search requests with the Semantic Lexicons been extended and optimized on the semantic level , understand search search intent , in order to more effectively search resources . Semantic Study of the LMS mainly in SCORM semantic research semantics of the LMS itself is still very rare , Moodle is pervasive at home and abroad applications LMS , the semantics of Moodle The study made ??an attempt . First secondary school physical example to create a domain ontology , add metadata information Moodle resources , and then added with the domain ontology semantic annotation , ontology - based semantic search Moodle resources on the basis of functional modules and Moodle to do based semantic search optimization . Experiments show that semantic scheme proposed in this paper is effective and feasible , their thoughts and methods based semantic search system of the body to achieve a reference on the theory and practice and learn the role .
