Lunch will be provided by Yahoo!. Speaker: Hua Ai (Intelligent Systems Program at University of Pittsburgh) Date/Time: Friday May 15, 2009, noon Location: 3002 Newell-Simon Hall (NSH) User Simulation for Spoken Dialog System Development Abstract: In this talk, I will present my thesis study on investigating how to evaluate and how to build user simulations to help dialog system development. When evaluating user simulations, I use both human judges and automatic evaluation measures to assess the simulation model qualities. When building user simulations, I examine three factors that impact simulation models in the tasks of dialog strategy learning and dialog system development. The talk is based on the author's ACL 2009 paper.

Lunch will be provided by Yahoo!. Speaker: Kai-min Kevin Chang (Language Technologies Institute, School of Computer Science, Carnegie Mellon University) Time & Date: Friday May 29, 2009, noon. Place: NSH 1507 (Note the room is not the usual NSH 3002) Title: Quantitative modeling of the neural representation of adjective-noun phrases to account for fMRI activation Abstract: Recent advances in functional Magnetic Resonance Imaging (fMRI) offer a significant new approach to studying semantic representations in humans by making it possible to directly observe brain activity while people comprehend words and sentences. In this study, we investigate how humans comprehend adjective-noun phrases (e.g. strong dog) while their neural activity is recorded. Classification analysis shows that the distributed pattern of neural activity contains sufficient signal to decode differences among phrases. Furthermore, vector-based semantic models can explain a significant portion of systematic variance in the observed neural activity. Multiplicative composition models of the two-word phrase outperform additive models, consistent with the assumption that people use adjectives to modify the meaning of the noun, rather than conjoining the meaning of the adjective and noun. This talk is based on the author's ACL 2009 paper.
