> For the past three years I have been developing a lexicography tool that I

> more input from non-Indo-European languages. In November I released
version

week.

interested.

domain.

collected

(Pardon

> useless in a language where there are no texts. Even when you have some
> texts, setting up the parser and manually adding entries to your database
> results in a small dictionary that is uneven in its depth and breadth of
> treatment. Even automating some sort of concordance program only results
in
> a simple list of words with no gloss and no semantic classification. I
> prefer to collect the words all at once, and use automated routines to
> develop the word list. Then as time and opportunity allows, use the text
> corpus method to collect natural examples of usage. Many lexicographers
> recommend investigating semantics within the context of semantic domains.
