In knowledge-based economy, technologic capability would be the core assets of enterprises, and technology management is considered one of the most important management activities. The foremost work of technology managers should be exploring technology trends to support technology planning. However, exploring technology trend is no longer concentrated in one disciplines, much innovative research results from integrating technologies developed in different disciplines. An automatic tool to help explore inter-discipline technology should be very useful for technology managers. Recently, some researches which through the patent documents to explore technology trend mostly identify the trend by patent map, described the technology trend each discipline separately, and can't explore inter-discipline trend to help technology manager broader vision. Moreover, most of discussing technology trend studies, even discovering emerging technology-the most popular topic, adopted the published patent documents written by English and based on USPTO for patent analysis. Seldom of patent analysis research collected patent documents written by Chinese-the most population language. Our research attempts to remedy the shortfall of aforementioned studies, and propose an integrated technique. The research utilizes common themes development methodology to identify multiple discipline and the methods work with patents written in Chinese. Our developed method does not try to predict future development, but try to present current technology development as it is in a succinct way to help technology managers make the judgment. Our system would provide inter-discipline technology analysis which across transmission technology and transmission of digital information technology, and the empirical experiment found twenty three inter-discipline technological subjects. Furthermore, extended experimental scope-added one discipline (image communication technology), our experiment found thirteen inter-discipline technological subjects.
