Extracting keywords from a target text data is essential for an analysis to describe substance characteristics of message content. We picked a use of a stopword filter from among alternatives because the method has the advantage that it is simple yet effective way. The filter we present was made up of non-content words and low-content words. Non-content-bearing words consisted mainly of function words and were gotten rid of by using part-of-speech (POS) tag information. High occurrence rate words in remaining had prospects of being keywords, however usually there were some low-content words like delexical verbs and so on. This article presents a stopword list obtained to come up with low-content words by sensuous manual procedures carried out using 40 text files from the CASTEL/J database and establishes it in the view of general versatility.

The purpose of this study is to explore changes of problem solving processes by diagrammatic externalizations. Eighteen undergraduate and graduate students attempted to solve a complicated arithmetic word problem (the 100 yen problem). Fourteen subjects were allowed to write down their own ideas, while other four subjects were prohibited from writing any idea. We stated the differences of their performance and the problem solving processes, comparing both experimental results of the two groups. The results indicated that (1) the subjects improved their performance for solving the 100 yen problem by externalizations, (2) integrating multiple propositions was facilitated by externalizations, (3) externalizing diagrams made the subjects effectively construct propositional networks that were relatively free from specific structures of the given problem.
