OpenCyc is the open source version of the Cyc technology, the world's largest and most complete general knowledge base and commonsense reasoning engine. OpenCyc can be used as the basis of a wide variety of intelligent applications such as:
* rapid development of an ontology in a vertical area
* email prioritizing, routing, summarization, and annotating
* expert systems
* games
to name just a few.
The Suggested Upper Merged Ontology (SUMO) and its domain ontologies form the largest formal public ontology in existence today. They are being used for research and applications in search, linguistics and reasoning. SUMO is the only formal ontology that
Bossam is a forward-chaining rule engine for the semantic web. Bossam is implemented based on RETE algorithm and supports OWL inferencing, URI referencing, negation-as-failure, java method attachment, query processing, and SWRL reasoning etc.
