Abstract
This study aimed to investigate the availability of correspondence analysis for use on text data obtained through interviews using photographs of workplace interiors. The text data, which have already been published, were obtained in the following manner. Twenty photographs of workplace interiors were presented to each participant, and each participant was requested to divide the photographs into groups based on similar impressions. Subsequently, the participants were asked about their impression of the companies and the people working there as well as the reason behind their impression. Morphological analysis of the obtained text data revealed that the nouns "“wood,” “pillar,” “ceiling,” “furniture,” “desk,” “chair,” “picture,” and “plant” were frequently used. These objects determined the impression obtained by looking at the photographs of workplace interiors. The adjectives “warm,” “calm,” “comfortable,” “friendly,” “bright,” “dark,” “cold,” and “stiff” were frequently used and expressed the impression of the photographs on the participants. For these frequently used words and photograph numbers, correspondence analysis was conducted, and the color characteristics of the photographs used in the interview were analyzed. Correspondence analysis distinguished the impressions of the photographs of workplace interiors. Moreover, combining correspondence analysis and color analysis clarified that the participants classified the photographs of workplace interiors based on the bright yellow and red of the wood. This result suggested that correspondence analysis could be used to evaluate the visual effect of wood interiors based on text data.
