PALC 2001 was the third conference of a bi-annual cycle of meetings focussing on practical applications of language corpora. The general topic of these conferences is the relationship between language corpora and their uses in a range of language and linguistic fields. Our aim is to provide a forum for practical exemplification of language corpora (written and spoken) in action and a forum for fruitful interaction between scholars. Thirty-five conference papers included in the present volume are all corpus-based. The themes cover Expert and Analytical Systems in Corpus Studies, Knowledge Extraction and Retrieval, National Corpus Projects, Corpus-based Linguistic Analyses including Contrastive Studies, ESP, and Corpus-based Cognitive and Discourse Analysis, Language Learning and Teaching and Learner Corpora, Translation Corpora and Translation Analysis. One section of the book includes papers from a round-table discussion on
Ontologies and Language Corpora.
