Even though evidence-based medicine has gained wide acceptance the physicians are unable to access the relevant information in the required time leaving most of the questions unanswered. This accentuates the need for fast and accurate biomedical question answering systems. In this paper we introduce INDOC a biomedical question answering system based on novel ideas of indexing and extracting the answer to the questions posed. INDOC displays the results in clusters to help the user arrive at the most relevant set of documents quickly. Evaluation was done against the standard OHSUMED test collection. Our system achieves high accuracy and minimizes user effort. Copyright 2007 Parikshit Sondhi et al.

INTRODUCTION An estimate of the around 14 million citations in PubMed 1 database of National Library of Medicine clearly indicates the exponential growth of published biomedical literature. It is thus impossible for any individual to keep pace with the advances. Thus though evidence-based medicine has gained wide acceptance 2-5 the physicians are unable to access the relevant information in the required time leaving most
