Creating Result Diagrams from Vague Requirements

Abstract

Companies plan and design new products or services by analyzing their customer needs. However, customers may not have clear understanding of their own needs, and often have only vague understanding of what the needs are. Therefore, in this study, we examine the method for organizing requirements and creating the result diagram based on such vague needs. An overview of the specific steps is as follows: 1) Perform morphological analysis of transcripts of interviews, the analysis which is used in text mining to extract each word for the languages with no space between words. 2) Based on the part-of-speech information added by the morphological analysis, derive the constituent elements that become the parts of the class diagram. 3) Draw a class diagram based on each element. In this paper, we present the result of the trial of this procedure by using actual interview data. Through this trial, we confirmed that this method would be an effective way to draw diagrams from vague needs.
