| Abstract |
The aim of this chapter is twofold. Firstly, we propose a method of specifying the concept that is too hard to describe in an exact way by a word or a phrase, by setting up the “relative distances" fr...om three key concepts; which we call a trichotomic approach to concept capture and representation, or description, in an approximate means. It is important and interesting that we can choose not only the key words but also other three “keys" such as patrons, books, concepts, objects or others. Then we arrange the objects of study according to the relative distances from these three keys, and investigate how these objects are distributed. Secondly, we demonstrate the usefulness of trichotomic approach through a couple of case studies applied to library’s loan record analysis. In these case studies, we discuss and compare the methods of choosing three keys, then we show how the trichotomic representation method is applied to the real data analysis. From these case studies, we are convinced of its high potential and importance as a visualization tool of the results of data analysis in general.show more
