 Typical output of an IR system – static predefined summary ◦ Title ◦ First few sentences  Not a clear view of the relation between document and the query  Hard for user to extract relevant information  Aim of the proposed approach ◦ Minimize need of referring to full text ◦ Provide enough information to support retrieval decisions

 Based on sentence extraction methods: ◦ Title method ◦ Location method ◦ Term occurrence information ◦ Biasing summaries towards queries

 50 randomly selected articles (TREC)  2 groups, each containing 10 people  Two types of ranked document list ◦ Query biased summary ◦ Static pre-defined summary  5 minutes to identify relevant documents

 Performing relevance judgments more accurately  Increasing the speed of user relevance judgments  Avoid the need of referring to full text
