Hi
I am not a computer literate person so what may seem a trivial task to some one who is, seems almost impossible to me; I just use them, I have no idea of how computers do what they do so please bear with me. I am retired and I read a lot of non-fiction papers and want to analyse the texts for meaning (what I see as implied by the author, not necessarily what he says). Some words could just be added to the appropriate dictionary (along with the sentence it appears in and my interpretation of it) for future use, others I would harvest from a wordlist creator. If I come across the term again then I could compare the two contexts thus building up a useful repository of knowledge. I hope this helps and thanks for your interest.
