Wandora's OpenCyc extractor (classifier) takes a term or multiple terms and retrieves related terms from OpenCyc web API. User has to select which kind of relations he/she is interested in. Available relation types are
- Generalizations aka Superclasses
- Specializations aka Subclasses
For example, user may start the extractor with File > Extract > Other > OpenCyc classifier and request classes for cats and dogs as shown below
Notice user has capitalized first letters in both search words. Capitalization is required as search words are strictly matched to OpenCyc terms and OpenCyc terms are capitalized. Successful extraction generates OpenCyc term subclass for Wandora class and potentially multiple instances for the OpenCyc term. In our example both Dog and Cat have classes in OpenCyc. Topics and OpenCyc originating associations are viewed below.
- Notice OpenCyc extractor generated associations and topics are not compatible with the Topic map conversion of OpenCyc.
