30 5 W. Gryc et al. Unsupervised Content Analysis The high-level challenge of our analysis of the Innovation Jam data is to identify the keys to success of such an endeavor, in particular, what are the characteristics of discussion threads that lead to innovative and promising ideas? The major diﬀerences between the Jam data and a typical forum are: a) the topics are more concentrated and controlled; b) the contributors are mostly from one organization, and therefore share similar concepts on basic values and what are the “great” ideas; c) the discussion time spans a shorter time.
A group of conversationalists can be characterized by a large number of posts and replies to each other. While the social network analysis of Innovation Jam participants is beyond the scope of the paper, it is important to note that the social structure of the Jam has an eﬀect on its outcomes. Newsgroups or forums can develop their own internal social structures. Groups can also be seen as those that develop unique linguistic or social traits . For example, groups may begin to use new words or acronyms, lending support to the idea that predicting convergence in discussions or brainstorms is possible.
This multi-stage format provides a rich set of data for investigation of how ideas evolve via moderated discussion. Of particular interest is whether we can detect characteristics of those discussion threads that can be linked to an idea ultimately being selected as a promising initiative. To the extent that selected ideas reﬂect some indication of “innovation,” we have some basis for examining which aspects of a discussion thread may lead to innovation. This paper summarizes our eﬀorts to characterize successful threads in terms of features drawn from both the thread content as well as information like the organizational divergsity of the participants in such threads.
