I'm looking for a dataset which will give me is-a and has-a type relations between senses (and give senses from words). WordNet seems to be the most popular model, but I'm trying to evaluate other possible sources (also WordNet doesn't support slang, txt-speak, or company/brand names, which I will eventually need, either in the database I use or merged into it somehow).
To clarify, I'm looking for data which I can process to give relations roughly like:
Chair: is-a Seat is-a Furniture is-a Physical Object is-a Entity
Finger: (part-of Hand part-of Human is-a Animal is-a Physical Object is-a Entity) OR (is-a Measurement Unit is-a Abstract Entity is-a Entity)
I haven't been able to find anything beyond WordNet or dictionary-scraping so far. Any suggestions?
