Comparison for /Open Cyc of 2007-10-02 23:41:31 and 2007-10-03 18:50:19

Additions:

Cyc (when compared to DBpedia) seems to follow a rather top-down approach – first more abstract concepts and entities are represented and later Cyc started to include also more domain knowledge. This seems to be reasonable, since domain knowledge changes faster and there is much more of it. On the other hand, domain knowledge is usually, what people need to solve real problems within their domains. DBpedia contains primarily domain knowledge, hence a combination of both – Cyc and DBpedia – could really be a winning team.

We plan to work on how DBpedia and OpenCyc can be fruitfully combined. For now, you can download an OWL/RDF version of Open Cyc from: http://sw.cyc.com/2006/07/opencyc_1_0.zip
