I'm creating a multilingual online dictionary and I need an open source English dictionary to work off of.
Wordnet is the obvious choice, as it's extremely complete and its license is permissive of commercial use, but unfortunately the senses are much too fine-grained for my purposes. Wordnet also contains many definitions that are too domain specific. For instance, when my users search "bus", I'd like them to see:
a vehicle carrying many passengers; used for public transport
bus topology, the topology of a network whose components are connected by a busbar
busbar, an electrical conductor that makes a common connection between several circuits
So one option is to perform sense clustering on Wordnet and then disambiguate between the resulting senses in a very general corpus of English text (and return only the most frequent senses)... ugh! I'm hoping someone has done this already? Or better yet there exists an open source, coarse-grained dictionary of general English that I'm not yet aware of? Many thanks to anyone who can point me in the right direction.
