Reordering Query and Rule Patterns for Query Answering in a Rete-Based Inference Engine

摘要

This paper describes implementation of a Rete based OWL inference engine and an optimization heuristic on this reasoner. This optimization heuristic modifies some well known optimization heuristics in needs of Semantic Web and represents a hybrid usage of them. This work measures the performance of these heuristics using Lehigh University Benchmark test data and compares the results with other common knowledge base systems. Also, some more improvements to the system is suggested as a future work.
