that correspondence analysis is not affected by text or corpus size is a further reason why I
have chosen to adopt correspondence analysis for the purposes of the current study.
4.4. Conclusion
The aim of this chapter has been to introduce correspondence analysis, and to demonstrate its
suitability to the current study. A correspondence analysis visualizes the complex
interrelations between qualitative variables and samples obtained by corpus-based language
studies. This means that correspondence analysis is particularly well suited to automatic text
categorization. Accordingly, I propose to utilize a correspondence analysis for 16 kinds of
data matrices for the pattern A DJ PR EP N in the current study. It is hoped that the output in a
two-dimensional plot will present a complex and detailed picture of the interrelations within
and between sub-disciplines of two academic disciplines (i.e. applied linguistics and business
studies) and their pattern use (see the details in Chapter 7). Such an analysis will also tell us in
more general terms whether a clear line can be drawn between the two disciplines in terms of
their adjective pattern usage.
sub-disciplinary corpus is somewhat different in its size respectively. Thus, I decided to use a correspondence analysis with
raw frequency data in the current study.
