DESCRIPTION:In scientific research\, it is often difficult to express info
 rmation needs as simple keyword queries. In this talk\, I will present a m
 ore natural way of searching for relevant scientific literature. Rather th
 an a string of keywords\, we define a query as a small set of papers deeme
 d relevant to the research task at hand. By optimizing a submodular object
 ive function based on a fine-grained notion of influence between documents
 \, our approach efficiently selects a set of highly relevant articles\, wh
 ile maintaining diversity in the result set. Moreover\, as scientists trus
 t some authors more than others\, we are able to personalize results to in
 dividual preferences.\n\nIn a user study\, researchers found the papers re
 commended by our method to be more useful\, trustworthy and diverse than t
 hose selected by popular alternatives\, such as Google Scholar and a state
 -of-the-art topic modeling approach.\n\nThis is joint work with Carlos Gue
 strin\, and is to appear at KDD 2011 in August.  (Link to the paper can be
