Date & Time

from
10:00 AM to
11:55 AM
Description
In this presentation we explore the contribution of corpora to Setswana lexicography. While corpora in the English-speaking world has been used in compiling dictionaries since the 1980s, many African languages still lack dictionaries. Many languages with dictionaries, must contend with dictionaries which were compiled without the benefit of corpus evidence. In this presentation will therefore look at the design of a Setswana corpus and how it is exploited to generate a frequency list (Kilgarriff, 1997) which informs the dictionary headword list. We also look at how the analysis of concordance lines are used to analyse the behaviour of different words in context (Sinclair, 1991) and aid in the extraction of multiword expressions and collocations. We complete our presentation by discussing the keyness measure which is used to isolate works which are key to a genre to enrich the dictionary macrostructure.
