Towards A National Study Guild

New post on blog@CACM: My presentation to President Obama’s Science & Technology advisory council (PCAST) on Education.

“Imagine a Facebook where the point is to study together, not trade pictures and jokes. Imagine a World of Warcraft where students earn levels and points by helping each other learn. Not a video game that teaches physics; instead, let’s create an educational experience that is social and game-like.”

A Case Base Planning Approach for Dialogue Generation in Digital Movie Design

We apply case based reasoning techniques to build an intelligent authoring tool that can assist nontechnical users with authoring their own digital movies. In this paper, we focus on generating dialogue lines between two characters in a movie story. We use Darmok2, a case based planner, extended with a hierarchical plan adaptation module to generate movie characters’ dialogue acts with regard to their emotion changes. Then, we use an information state update approach to generate the actual content of each dialogue utterance. Our preliminary study shows that the extended planner can generate coherent dialogue lines which are consistent with user designed movie stories using a small case base authored by novice users. A preliminary user study shows that users like the overall quality of our system generated movie dialogue lines.
