This paper describes the SubCat-Extractor as a novel tool to obtain verb subcategori-sation data from parsed German web corpora. The SubCat-Extractor is based on a set of detailed rules that go beyond what is directly accessible in the parses. The extracted subcategorisation database is represented in a compact but linguistically detailed and flexible format, comprising various aspects of verb information, complement information and sentence information , within a one-line-per-clause style. We describe the tool, the extraction rules and the obtained resource database, as well as actual and potential uses in computational linguistics.
