The invention relates to a method and a computer system for enhanced part-of-speech
(POS-) tagging as well as grammatically disambiguating a phrase. A phrase is usually
a short multiword expression that may be ambiguous. By introducing grammatical
constraints the invention supports POS-tagging as well as grammatically disambiguating
the phrase. According to an identifier for the phrase, the phrase is supplemented
with artificial context information. The supplemented phrase is then POS-tagged
or grammatically disambiguated. Important applications are POS-tagging, Automatic
Term Encoding, Headword Detection and Information Retrieval.
