These anecdotes and a limerick humorously celebrate the life and work of Charles S. McCoy.

My name is Doug Adam. I am a convicted felon. I turned myself in, in mid-1987, to a U.S. attorney in New York, pleading guilty to felony charges of tax fraud and fraud on a mutual fund. It leftme scared to death, millions of dollars in debt, with no job, and at the age of37 back living with my parents while I awaited sentencing. What began then was a painful process of self discovery. After thriving on competition and perfection all (...) my life, how could I admit I wasn't perfect? Perfection wasn't even close. I was a felon. (shrink)

One of the challenging problems in large scale cyber-argumentation platforms is that users often engage and focus only on a few issues and leave other issues under-discussed and under-acknowledged. This kind of non-uniform participation obstructs the argumentation analysis models to retrieve collective intelligence from the underlying discussion. To resolve this problem, we developed an innovative opinion prediction model for a multi-issue cyber-argumentation environment. Our model predicts users’ opinions on the non-participated issues from similar users’ opinions on related issues using intelligent (...) argumentation techniques and a collaborative filtering method. Based on our detailed experimental results on an empirical dataset collected using our cyber-argumentation platform, our model is 21.7% more accurate, handles data sparsity better than other popular opinion prediction methods. Our model can also predict opinions on multiple issues simultaneously with reasonable accuracy. Contrary to existing opinion prediction models, which only predict whether a user agrees on an issue, our model predicts how much a user agrees on the issue. To our knowledge, this is the first research to attempt multi-issue opinion prediction with the partial agreement in the cyber-argumentation platform. With additional data on non-participated issues, our opinion prediction model can help the collective intelligence analysis models to analyze social phenomena more effectively and accurately in the cyber argumentation platform.
