Description: Comparison sentences represent a rhetorical structure that is commonly used to communicate the findings of an empirical study. Although the overall percentage of comparison sentences in an article is rather small (in the four biomedical collections examined it hovered around 5% of the overall number of sentences) comparisons are rich with information that relate how the properties of one entity relate to that of a compared entity. The richness of information conveyed through comparison sentences, however, is generally underutilized. This dissertation proposal aims to tease out the crucial facets of a comparison claim (Blake, 2010) which represents an important step towards summarizing the information conveyed through comparative sentences across texts. The proposal analyzes the complexity of comparison sentences and suggests methods for the identification of four crucial components of comparison sentences: agent, object, basis of comparison as well as the relation that binds the three entities.
 
Bios:
Ana Lucic is a doctoral student at the University of Illinois Graduate School of Library and Information Science. Her research goals involve extracting information from text that allow innovative ways of looking at, analyzing, and summarizing text.

Dr. Blake is an Associate Professor in the iSchool (GSLIS) at the University of Illinois at Urbana-Champaign  with joint appointments in the Department of Computer Science and Medical Information Science. She serves as Associate Director of the Center for Informatics in Science and Scholarship (CIRSS) along with the Director Bertram Ludäscher and is an active member of the Socio-technical Data Analytics (SODA) group. Her primary research goal is to accelerate scientific discovery by synthesizing evidence from text. Her techniques embrace both automated and human approaches that are required to resolve contradictions and redundancies that are inevitable in the information intensive world in which we live.
