Leveraging data from Kickstarter, we unveil a “V-shaped” relationship between creators’ funding attainment discrepancy (the gap between realized and target performance) and their tendency to explore novel project categories.

First, snippet encoding is formulated as a multi-criteria optimization problem in which information sources are incorporated to distill consumer-appealing keywords considering both driving search and attracting selection, as well as to integrate the perspectives of sellers and consumers.
