I suppose I could take a text and remove high frequency English words from it. By keywords, I mean that I want to extract words that are most the characterizing of the content of the text (tags ) . It doesn’t have to be perfect, a good approximation is perfect for my needs.
Has anyone done anything like that? Do you known a Perl or Python library that does that?
Lingua::EN::Tagger is exactly what I asked however I needed a library that could work for french text too.
You could try using the perl module Lingua::EN::Tagger for a quick and easy solution.
A more complicated module Lingua::EN::Semtags::Engine uses Lingua::EN::Tagger with a WordNet database to get a more structured output. Both are pretty easy to use, just check out the documentation on CPAN or use perldoc after you install the module.
