Mining Broad Latent Query Aspects from Search Sessions

by Xuanhui Wang, Deepayan Chakrabarti, Kunal Punera - KDD '09 , 2009
"... Search queries are typically very short, which means they are often underspecified or have senses that the user did not think of. A broad latent query aspect is a set of keywords that succinctly represents one particular sense, or one particular information need, that can aid users in reformulating ..."

that uses single-keyword reformulations: a gain of 14 % and 23 % in terms of human-judged accuracy and click-through data respectively, and around 20 % in terms of consistency among aspects predicted for “similar ” queries. This demonstrates both the importance of broad query aspects, and the efficacy

Data integration and query reformulation in service-based grids

by Carmela Comito, Domenico Talia, Anastasios Gounaris, Rizos Sakellariou - In Proc. of the 1st CoreGRID Integration Workshop , 2005
"... This paper describes the XMAP data integration framework and query reformulation algorithm, provides insights into the performance of the algorithm, and about its use in implementing query processing services. Here we propose an approach for data integration-enabled distributed query processing on G ..."

Reformulations of Rational Functions of 0-1 Variables

by Mohit Tawarmalani, Shabbir Ahmed, Nikolaos V. Sahinidis , 2001
"... We present mix5UqC teger linear programming reformulations of rational functions of 0-1 variables and analyze the tightness of the corresponding linear relax ations. In the process of doing so, we develop a number of new results. First, we consider the product of a single continuous variable and the ..."

Coping with the Variability of Medical Terms

by M. Fieschi Et Al. (eds, Robert H Baud, Patrick Ruch, Arnaud Gaudinat, Paul Fabry, Christian Lovis, Antoine Geissbuhler, Robert H Baud , 2004
"... Objectives: To cope with medical terms, which present a high variability of expression through a single natural language, in the sense that any term may be reformulated in hundred of different ways. Methods: A typology of term variants is presented as a systematic approach in order to favour the imp ..."

CuZero: Embracing the Frontier of Interactive Visual Search for Informed Users

by Eric Zavesky, Shih-fu Chang
"... Users of most visual search systems suffer from two primary sources of frustration. Before a search over this data is executed, a query must be formulated. Traditional keyword search systems offer only passive, non-interactive input, which frustrates users that are unfamiliar with the search topic o ..."

Semantic

While traditional information retrieval techniques that return a single ranked list of docu-ments are quite common for such tasks, they may not always be ..."

We evaluate this novel knowledge-driven approach using precision and recall metrics on the 2006 TREC Genomics Track. Keywords-semantic predications, question answering, back-ground knowledge
