Speaker: Lori Lorigo, PhD Student, Information Science, Cornell University

Date: Wednesday, April 13, 2005 4:15-5:15p

Location: 301 College Avenue, Seminar Room

In a special series, the next two IS Seminars will feature Information Science’s first class of graduate students, Jofish Kaye, Gilly Leshed, Lori Lorigo, and Sadat Shami. They will be presenting their recent research on a wide variety of Information Science topics, from the notion of context in knowledge networks to issues of anonymity, affect and collaboration in online communication. Each student will present their work for 20 minutes and take questions for 10 minutes.

This will be an excellent opportunity to see current work by our graduate students. Please make every effort to attend.

Abstract -

This talk will introduce three projects in which context, or placement in a network, adds significant meaning and utility. Instead of studying objects in a digital collection alone, I focus on the relationships between those objects, and how that relationship can be used to aid new discovery. In my research, I am working with applications including (1) a digital library of mathematics, (2) behavioral data about interaction with a web search engine, and (3) scholarly research articles published in the physics e-print arXiv. In the context of the library of mathematics, which will be the primary focus of the talk, I describe work utilizing and extending hyperlink analysis algorithms such as HITS, or Hypertext Induced Topic Selection to better understand and classify mathematical objects. Time permitting I may also discuss another of the projects.

Bio -

Lori Lorigo is a PhD student in the Information Science program at Cornell. She completed her A exams in the fall and is working with her committee of Professor Robert Constable, Professor Geri Gay, and Professor Thorsten Joachims on her thesis. Her interests span the Information Science field, with a focus on information systems and HCI. She is presently on a Cognitive Science Dissertation Fellowship, awarded both for her work with eye tracking, studying cognitive behaviors during web search, and for the interdisciplinary nature of her research.
