Graff, thank you very much for the explanation
This depends on what particular things you want to extract that go beyond just the individual words that get "noun" tags. Multi-noun referring expressions (e.g. "corner store", "Perl Hacker")? Phrases that include function words and/or adjectives? Arguments (subjects and/or objects) of verbs?

Probably I should have better explained my purpose. I extract 1-5 gram phrases. For example for site "horses dot com" I get: "saddle | stable blankets sheets tail bags | bridles english arena | stable supplies halters | chinks cinches ...." etc.
This is just a part of the project and I unfortunately cannot afford doing manual tagging, creating training sets, etc.
So what I am looking for is a working software, which does a similar extraction for Dutch, as Lingua::EN::Tagger for English written in Perl.
