Analysis of Frequent Words Used in Townscape Control Standards

Abstract

Making rules on urban design has become more important to sustain good townscape. This paper deals with townscape control standards which were made before Landscape Act was established. It is intended to identify what words are frequently used in townscape control standards, using morphological analysis and word frequency analysis, and why these words are extracted. These two analyses have extracted thirty words which are frequently used in townscape control standards. It has been found that three words, "Tsutomeru", "Hairyo" and "Chowa" reflect characteristics of autonomous townscape ordinance. From the results of dual scaling it is shown that "Tsutomeru" is correlated with townscape control standards on space use, and "Hairyo" and "Chowa" are correlated with townscape control standards on exterior design.
