Query Technology Research of Educational Information Based on 5W1H

In order to solve these problems such as the rapid growth of educational information based on internet and the increasing complexity of information retrieval,the query architecture is proposed using ontology technology which has a four-layer structure.The concepts and relationships are summarized in the ontology by 5W1H analysis method,and a conceptual model of the ontology based on 5W1H established;the persistence technology and the ontology rule-based reasoning technology is mainly researched,and the query rules based on SPARQL and the information query algorithm based on Jena reasoning rules are designed.For example,the query functions such as precise query,fuzzy query and semantic query are realized by using Jena and MySQL under the ontology query system of teacher's information.
