Chung and Nation developed a rating scale to classify all the words in a university textbook into four categories according to their degree of technicalness. The two textbooks analysed for the study were in anatomy and applied linguistics, both fields in which Chung has university qualifications.
Thus, Chujo and Utiyama's (2006) work is promising, in that it may provide an automated alternative to Chung and Nation's (2003) rational basis for identifying degrees of technicalness in the vocabulary of a particular register.
The raw lists from the output of corpus analysis are likely to need editing according to various criteria, including decisions about which categories of words (in terms of Chung and Nation's (2003) scale of technicalness) should be included, and a checking procedure to ensure that frequent words also occur across a range of texts within the register.
