Enhancing the Effectiveness of Information Retrieval Systems

My primary research interest revolves around developing better information retrieval systems. I address this goal from three broad perspectives. First, I study techniques for enhancing the effectiveness of Information Retrieval (IR) systems leveraging machine learning algorithms. Second, I investigate methods for improving the efficacy of IR evaluation using statistical methods. Third, I make use of the abundant availability of “Big Data” to increase the range of information needs that can be addressed and to generate several types of useful insights. I find my passion in introducing new research problems. I then address these novel problems with classic solutions where possible, or I propose novel solutions (see Table 1).
