CKLingo is an approach to searching large linguistic datasets across knowledge domains, from legal to financial and beyond, and presenting aggregates. For example, one could query a collection of posts using the string, "I've lived in" and possibly end up with the places that the author(s) has/have lived in, or whatever the demand may be.
If you are interested in a demonstration, you could enter a search string below ("I" may be a good place to begin). Please note this is a very limited dataset.
