[Corpora-List] Criteria for an ESP Vocabulary List

Thu Apr 24 08:00:46 UTC 2008

dear Mahmud and list,

I agree with Adam here that vocabulary lists (aka word-lists) are probably
not the best place to start from, whether for ESP or for ESL in general. The
main reason for this is that, as we all know, the most frequent words are
also the most polysemous and occur in the widest variety of structures.
Certainly, collocations listings would be a more profitable place to start,
as collocates limit the extent of the polysemes' meanings and behaviour; and
generation of 3- 4- and 5-grams, skip-grams and concgrams would give a very
good indication of what phraseology to include in the ESP syllabus. You
could then extract vocabulary lists from those n-grams, focusing on the
forms (and hence the meanings) that are actually used in the sector you're
interested in.
This focus on meanings, rather than word forms, is discussed with reference
to the AWL here:
K. Hyland & P. Tse (2007) "Is there an academic vocabulary?", Tesol
Quarterly 41 (2) pp. 235-253

Food for thought.

best,
Gill
