Abstract

Companies need to identify technology convergence in order to get early warning signals to detect new risks and opportunities. The purpose of this paper is to provide a novel method for identifying different movement patterns of technology convergence by means of a semantic analysis approach using patent data. We illustrate this method on the basis of four distinct application technologies of ultraviolet light emitting diodes (UV-LEDs). Developing semantic anchor points for these four application technologies and calculating semantic similarity values for all pairs of patents and anchor points enables the identification of and separation between one-way and two-way technology convergence by means of statistical analysis.
