Abstract

For overcoming the existing problems in Web based learning system when network blocking or disconnection happens, a new architecture of the Web based learning system based on semantic caching is proposed; also, the model and the query processing mechanism of semantic caching are described in detail. Furthermore, this paper proposed and proved 11 simplification rules, which can be used to optimize the query processing of semantic caching, and the optimized query-processing algorithm is thoroughly described.

Keywords

Query Processing Learning Server Query Evaluation Disjunctive Normal Form Local Cache 
These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
