20. FLAX vs BNC?

  • Limitations with representativeness

Identifying register on the Web is difficult (Biber& Kurjian, 2007)
Successful corpora are based on domains, genres, collections of document types
The web is a dirty corpus (Kilgariff& Grefenstette, 2003)
FLAX cleaned by 30% using BNC wordlist
Linked externally to BNC, Yahoo
Complementary sources, both with limitations
