Overview
• Understanding & measuring innovation is hard• Citation analyses lack important context• Semantic distance can help enrich these
measures• Applying these measures shows recent
changes in the way knowledge is recombined and the way ideas diffuse
Combinatorial Innovation• The generation of new ideas and inventions
relies on combining preexisting ideas.
Understanding Innovation & Measuring Impact
• Understanding patterns of idea recombination is difficult
• Likewise, impact measures are coarse• Citation counting is inexact• Metadata not ideal
Semantic Distance
• Citation measures can be weighted by accounting for content
• Proximate and Distant citations are qualitatively different
