Core basic course group construction in computer major

In order to change talent training situation in computer major, and to meet the talent training goal, i.e. solid foundation, broad knowledge, strong ability and high quality, a core basic course group of computer major was established. The course group includes advanced language programming, database principle, operation system and related integrative practice as well. We carried out comprehensive teaching reform within the course group. After teaching reform, we established three platforms for talent training: knowledge learning, engineering practice, and research innovation. Also, a perfect talent training system gradually formed which contains four levels: design-oriented, application-oriented, integration-oriented, and innovation-oriented.

Hierarchical Semantic Overlay Network

A hierarchical semantic overlay network model HSON is put forward. In HSON, peers with resources of identical semantic are connected together to form SON. The semantics of SONs are associated with ontology concepts, and the hierarchical structure of ontology concepts is utilized to hierarchically organize all SONs. SONs with similar semantic are directly connected with each other. The structure of HSON is beneficial to query process. In contrast to flooding, queries are purposefully forwarded to destination SONs. Simulation results showed that hierarchical semantic overlay network model could improve recall, accelerate query routing process, and reduce the number of messages in the network.
