Abstract

The creation of questionnaire forms based on research papers has been done for various purposes. In previous studies, the surveyor intentionally created questions to be used in questionnaires based on secondary research and the knowledge of the researcher, and it is unclear what procedure was used to create the questions. Therefore, in this study, we examined and discussed methods of mechanically creating questions based on a review of research papers. As a result, we proposed a new method to create questions by mechanically combining words obtained from the article search, text mining of extracted articles, and co-occurrence word search.

Abstract

In development of technology and product, it’s important to make decisions based on technology trend. Some previous studies obtained technology trend based on patent information. In our previous study, we tried to investigate the state of innovation and the emergence of dominant design by using patent information. We analyzed inkjet printers and NC machines with theme codes and F term codes in Japanese patent classification codes. In this study, we tried to know the change of technology of other products other than inkjet printers or NC machines by using patent information. The target product of this study is camera. Camera products changed its key technology of imaging and recording from analogue film to digital imaging sensor and semiconductor memories. We attempted to obtain this change by using patent information.

Abstract

Companies are required to understand the external environment, develop growth strategies, and implement them. One aspect of the external environment is the market itself. To understand customer needs, we use patent information as the approach from the product, rather than the approach of listening to the voice of the customer, based on the three levels of product. We proposed a method to show the value of a product based on the concept of commonality and uniqueness by comparing multiple samples. In the case of projectors, Japanese patents were analyzed. We conclude that the common content represents the core benefits of the product, and that the characteristic content represents the product attributes
