OpenCyc can be used as the basis for a wide variety of intelligent applications such as
speech understanding (using the KB to prune implausible choices via common sense, discourse context, and prosodics)
database integration (using the KB as an interlingua through which semantic joins occur automatically via back chaining) and consistency-checking
rapid development of an ontology in a vertical area (by extending and growing the OpenCyc KB in that area, using the OpenCyc Rapid Theory Formation toolkit)
email prioritizing, routing, summarizing, and annotating
to name just a few. If you have ideas or suggestions, you can send them to us at firstname.lastname@example.org or discuss them on the OpenCyc discussion forum on SourceForge.
