A method for recognizing user requirements in telecommunication services

摘要

This method is based on compensating for any information that is missing because it is too difficult for the user to describe, by discerning the user's intention from the information that is easy to describe. The authors introduce the STR service description language and propose the interface for inputting user requirements. They classify the specification's information from the user's viewpoint, that is, whether or not it can be easily understood. The information is then grouped according to how difficult it is for the user to describe it. Then, a user interface is proposed that can easily input information that even laymen can describe. With this interface, the information input by the user is limited to that judged easy to describe, and some information is acquired by means of question and answers. The user's intention is determined by analyzing the difference between input information and the existing specification. Then, information judged difficult to describe is compensated for and a complete specification is obtained. However, there is a fear that the specification which the system generates may be excessive. Then, a support system is presented to confirm the suitability of a generated specification.
