CIS Department Talk - April 10, 2008

The Department of Computer and Information Science & The Society of Computer Science Present

Speaker:Elena Filatova, Columbia University, Department of Computer Science
Topic:Answering Event-Related Questions
Date:April 10, 2008, 2:30PM
Place:John Mulcahy Hall, Room 132


Question-answering is a challenging research problem, which has attracted significant attention over the last few years. In my talk, I will first introduce the task of question-answering and discuss approaches for creating answers to factoid and open-ended questions. Then, I will present an approach that I developed for answering event-related open-ended questions that uses domain templates, for different event domains (for example, "earthquake" domain or "presidential election" domain). Currently, domain templates for information extraction (IE) tasks are created manually. I will describe a completely automatic procedure for generating domain templates, using a set of similar domain events. Finally, I will describe a "biography" domain and will talk about my research on identifying general biographical activities as well as activities typical for representatives of a particular occupation.
