1986 Very Large Data Bases Conference  
Work the number approaches three million), RN' size appears to grow only linearly with deductive c0mplexit.y.  ...  Keeping the representation of deductive associations as compact as possible greatly simplifies the process of incremental compilation of the rule base.  ...  Current logic-based knowledge processing systems typically involve a considerable amount of query-time deductive search.  ...

Semantic query processing in object-oriented databases using deductive approach

S. C. Yoon, I. Y. Song, E. K. Park
1995 Proceedings of the fourth international conference on Information and knowledge management - CIKM '95  
In the rule generation step, we generate a set of deductive rules based on an object-oriented database schema or semantic knowledge about the domain of the database.  ...  In the semantic knowledge compilation step, we compile semantic knowledge together with object-oriented database schema to identify semantic knowledge that is potentially relevant(beneficial) to each class  ...  In the rule generation phase, we generate a set of deductive rules based on the above object-oriented database schema or semantic knowledge.  ...
