Few would argue that technology has driven numerous innovations. Therefore, the body of literature has been almost unanimous in employing patent information to identify opportunities. Previous studies using patent database employed a frequency-based approach, which assumes that frequent keywords play a key role in innovation. However, innovations can occur not only from frequent trends, but also from infrequent trends. Some previous research, albeit infrequent, has attempted keygraph approach in order to reflect infrequent trends to the new innovation development. Despite the effort, however, little is known about effective interpretation of keygraph results to identify new opportunities. Therefore, we suggested a keygraph-based approach combined with the index-based validation approach. We conducted a case study on healthcare services to illustrate the effectiveness of the proposed approach.

如何确定技术创新的有希望的机会:基于关键指标的专利分析

很少有人会争辩说技术驱动了许多创新。因此,文献系统在采用专利信息来识别机会方面几乎是一致的。以前使用专利数据库的研究采用的是基于频率的方法,该方法假定频繁使用的关键字在创新中起关键作用。但是,创新不仅可以从频繁的趋势中发生,而且可以从不频繁的趋势中发生。以前的一些研究(尽管很少)尝试使用键盘图方法来反映新创新发展的罕见趋势。尽管付出了很多努力,但是对于有效解释关键点结果以发现新机会知之甚少。因此,我们提出了一种基于关键图的方法和基于索引的验证方法。
