Abstract

When inexperienced designers develop software usingObject-Oriented method, there are the following problems: (a) thereis not enough functions for the software and (b) there is a lack ofconsistency among Unified Modelling Language (UML) documentsdeveloped. In this paper, we propose an efficient developmentmethod of adequate UML documents which can be used by inexperienceddesigners. This method consists of three countermeasures: (1)develop requirement specifications that contain all informationnecessary for development of UML documents using Natural LanguageProcessing (NLP), (2) share all information about developed UMLdocuments and reuse it when developing other UML documents and (3)decide on a UML document development process for inexperienceddesigners. To evaluate proposed method, we conducted experimentsand used questionnaires. The results show a correct answer ratebecame 120[%] for the proposed method in comparison with theconventional method, development time became 80[%] and usabilitywas improved.
