A Sequential Pattern-Based Method for Mining Technological Context and Developing R&D Strategies for the Cloud Computing Industry

Aims: Cloud computing has been a hot topic in recent years, yet its technology trend is rarely comprehensively studied in peer-reviewed publications. Owing to a great number of professional and technical terms and the increasing volume of technical data presented in patents, it is difficult to analytically identify the timeframe of technological development. Methods: To remedy this problem, this study uses a sequential pattern method and social network analysis to develop the technological context of cloud computing. Results & Discussion: The analysis of relative patent position, technology quality, and technology life cycle was incorporated. Conclusion: This study proposes a method of patent portfolio analysis on the technological level to assist managers of cloud computing enterprises in developing competitive research and development (R&D) strategies.
