Raju, Santosh, Kumar, Shaishav and Udupa, Raghavendra (2010): Suggesting related topics in web search. In: Proceedings of the 33rd Annual International ACM SIGIR Conference on Research and Development in Information Retrieval 2010. p. 705.

Suggesting topics that are related to user's goal or interest is very important in web search. However, search engines today focus on suggesting mainly reformulations and lexical variants of the query mined from query logs. In this demonstration, we show a system that can suggest related topics for a query based on the top search results for the query. It can help users in exploring the topics related to their information need. The topic suggestion system can be integrated with any search engine or it can be easily installed on the client machine as a browser plugin.

Kumar, Shaishav and Udupa, Raghavendra (2010): Multilingual people search. In: Proceedings of the 33rd Annual International ACM SIGIR Conference on Research and Development in Information Retrieval 2010. p. 708.

People Search is an important search service with multiple applications (eg. looking up a friend on Facebook, finding colleagues in corporate email directories etc). With the proportion of non-English users on a steady rise, people search services are being used by users from diverse language demographics. Users may issue name search queries against these directories in languages other than the language of the directory, in which case the present monolingual name search approaches will not work. In this demo, we present a Multilingual People Search system capable of performing fast name lookups on large user directories, independent of the directory language. Our system has applications in areas like social networking, enterprise search and email address book search.

Udupa, Raghavendra and Bhole, Abhijit (2010): Investigating the suboptimality and instability of pseudo-relevance feedback. In: Proceedings of the 33rd Annual International ACM SIGIR Conference on Research and Development in Information Retrieval 2010. pp. 813-814.

Although Pseudo-Relevance Feedback (PRF) techniques improve average retrieval performance at the price of high variance, not much is known about their optimality and the reasons for their instability. In this work, we study more than 800 topics from several test collections including the TREC Robust Track and show that PRF techniques are highly suboptimal, i.e. they do not make the fullest utilization of pseudo-relevant documents and under-perform. A careful selection of expansion terms from the pseudo-relevant document with the help of an oracle can actually improve retrieval performance dramatically (by > 60%). Further, we show that instability in PRF techniques is mainly due to wrong selection of expansion terms from the pseudo-relevant documents. Our findings emphasize the need to revisit the problem of term selection to make a break through in PRF.

Kulkarni, Chinmay E., Raju, Santosh and Udupa, Raghavendra (2010): Memento: unifying content and context to aid webpage re-visitation. In: Proceedings of the 2010 ACM Symposium on User Interface Software and Technology 2010. pp. 435-436.

While users often revisit pages on the Web, tool support for such re-visitation is still lacking. Current tools (such as browser histories) only provide users with basic information such as the date of the last visit and title of the page visited. In this paper, we describe a system that provides users with descriptive topic-phrases that aid re-finding. Unlike prior work, our system considers both the content of a webpage and the context in which the page was visited. Preliminary evaluation of this system suggests users find this approach of combining content with context useful.
