BM patent evolution map for tracking the development of E-service

Given that the study on the creation and operation of e-service is an important research field, the challenges of developing systematic and scientific methodology for the analysis of e-service operation and creation still carry on. This research attempts to suggest a systematic approach to identify the evolution of e-service based on the BM patent database as a quantitative database. Despite the considerable contribution that BM patents can bring to the service world as a valuable database, only a few studies have been conducted on them. This research proposes an algorithm for constructing a BM patent evolution map by selecting major arcs in the patent citation network. Furthermore, the algorithm is applied to the e-finance field to construct and evolution map. The results of this research can be used to understand the process of evolution of e-service, extracting fruitful new service ideas from existing e-service processes or methods, and identifying the legal rights and limitations of created e-service concepts and operation methods.
