DESCRIPTION:We investigate the extraction of ontologies from biological\nt
 ext using a semantic representation derived from a robust parser. The\nuse
  of a semantic representation avoids the problems that traditional\npatter
 n-based approaches have with complex syntactic constructions and\nlong-dis
 tance dependencies. The discovery of taxonomic relationships is\nexplored 
 in a corpus consisting of 12\,200 animal-related articles from\nthe online
  encyclopaedia Wikipedia. The semantic representation used is\nRobust Mini
 mal Recursion Semantics (RMRS). Initial experiments show\ngood results in 
 systematising extraction across a variety of hyponymic\nconstructions.
