We describe the use of XML tokenisa- tion, tagging and mark-up tools to pre- pare a corpus for parsing. Our tech- niques are generally applicable but here we focus on parsing Medline abstracts with the ANLT wide-coverage grammar. Hand-crafted grammars inevitably lack coverage but many coverage failures are due to inadequacies of their lexi- cons. We describe a method of gain- ing a degree of robustness by interfac- ing POS tag information with the exist- ing lexicon. We also show that XML tools provide a sophisticated approach to pre-processing, helping to ameliorate the ‘messiness’ in real language data and improve parse performance.
