Service logic program generation method using specification supplementing techniques

Specification supplementing techniques used to efficiently create service logic programs (SLPs) are discussed. Our techniques significantly reduce the volume of service specifications that need to be described by supplementing both the specifications that can be automatically determined from other specification information, and those that have default values or procedures. Our experimental results show that a variety of supplementing techniques achieve a stable supplementing ratio for any kind of SLP, and that the ratio improves as the target SLPs become more complicated. We begin by presenting an overview of NTT´s advanced intelligent network (IN) architecture and describe a service creation environment (SCE). Then we discuss a service logic program (SLP) creation system in the SCE, and describe the issues related to a practical application of the SCE
