: We demonstrate an approach and an accompanying UNIX toolbox for performing wtrious kinds of Knowledge tT,xlractions and Structuring. The goal is to "practically" enhance the productivily while constructing resources for NLP systems on the basis of large corpora of technical texts,. Users are lexicon/grammar builders, terminologists and knowledge engineers. We stay open to already explored methods in this or neighbouring activities but put a greater stress on the use of linguistic knowledge. The originality of the work presented here lies in the scope of applications addressed and in the degree of use of linguistic knowledge.
