Summarization on the vortex engine technique applied in coal mine gas generate electricity

Design on reasoning engine of mine fan fault diagnosis expert system;

It noticeably increases the efficiency of reasoning engine.

The framework makes use of the characteristics of concept of norms,rich semantic and level relations of the Ontologe and combines the knowledge warehouse of Ontologe and the first-order predicate reasoning engine on the user\'s query to process the result and make users get ultimately information that matchs with search requests in a higher state.

,the offline subsystem,including data preparation and URL clustering based on user s browsing paths,and the online subsystem,including a recommendation engine and a Web HTTP server.

It proposes a design plan to implement the recommendation engine using association rules in the end.

With schema mapper, a semi-automatic tool is demonstrated for schema integration that combines a novel visual interface with an algorithm-based recommendation engine to cope with such a challenging problem.
