Extension of Computer Programs for English Vocabulary Analysis Using Shell Script

Abstract

The author has proposed and developed computer programs which make it possible to analyze English corpus and to make word lists from those corpus. The purposes of this study were to develop a new computer program that measures the range of words used in different types of corpus, to improve the computer programs, which had been developed in the earlier study, in order to deal with corpus with part-of-speech (POS) tags and to measure the processing time to judge whether these programs were useful or not. In this study, two kinds of RANGE program were newly developed and six programs of the previous study were revised. Five programs out of six could be considered to be useful, however, one program was not sufficient and needed to take some measures.
