Shuang-Hong Yang, Ryen W. White, Eric Horvitz
2013 Proceedings of the 36th international ACM SIGIR conference on Research and development in information retrieval - SIGIR '13  
The findings highlight the promise of using geocoded search for sensing and predicting activities in the world.  ...  With consent, the devices can also provide streams of information about search activity and location that can be used in population studies and real-time assistance.  ...  We did not observe significant changes in the use of question words in mobile medical queries over the course of the engagement.  ...

Quicklink selection for navigational query results

Deepayan Chakrabarti, Ravi Kumar, Kunal Punera
2009 Proceedings of the 18th international conference on World wide web - WWW '09  
Since the real-estate on a search results page is constrained and valuable, picking the best set of quicklinks to maximize the benefits for a majority of the users becomes an important problem for search  ...  We first demonstrate the hardness of the objective, and then propose an algorithm that is provably within a factor of (1 − 1/e) of the optimal.  ...  Acknowledgments We thank Youssef Billawala, Will Chin, Arah Cho, and Yong Gao for providing us data.  ...

Articulating information needs in XML query languages

Jaap Kamps, Maarten Marx, Maarten de Rijke, Börkur Sigurbjörnsson
2006 ACM Transactions on Information Systems  
Our main experimental findings are: First, while structure is used in varying degrees of complexity, two thirds of the queries can be expressed in a fielded-search like format which does not use the hierarchical  ...  How does the expressiveness of languages for querying XML documents help users to express their information needs? We address this question from both an experimental and a theoretical point of view.  ...  ACKNOWLEDGMENTS We thank the participants of the Topic Format Working Groups at INEX 2002INEX , 2003INEX , and 2004.  ...

Ontology-based end-user visual query formulation: Why, what, who, how, and which?

Ahmet Soylu, Martin Giese, Ernesto Jimenez-Ruiz, Evgeny Kharlamov, Dmitriy Zheleznyakov, Ian Horrocks
2016 Universal Access in the Information Society  
In this respect, visual methods for query formulation undertake the challenge of making querying independent of users' technical skills and the knowledge of the underlying textual query language and the  ...  An ontology is more promising than the logical schema of the underlying data for guiding users in formulating queries, since it provides a richer vocabulary closer to the users' understanding.  ...  Casual users and domain experts with no technical background could benefit the most from visual query formulation and the ultimate benefit of it questionable for IT experts, since in many cases they might  ...

From models to data: A prototype Query Translator for the cadastral domain

Claudia Hess, Marian de Vries
2006 Computers, Environment and Urban Systems  
The missing possibility of exchanging cadastral information between diVerent countries in an eYcient way leads to rather complicated procedures of collecting and analyzing cadastral data in land transactions  ...  Cross-border exchange of cadastral information is not only interesting in the real property Wnancial market, but also for authorities, for example in land management and infrastructure development, and  ...  However, the placeholder classes are strictly conceptual and do not have a 'structure' in the sense of a list of attributes.  ...

Predicting the effectiveness of queries and retrieval systems

Claudia Hauff
2010 SIGIR Forum  
Web Resources A number of recent studies take advantages of resources from Web search engines such as interaction logs, query logs and the Web graph (W).  ...  Moreover, in a dynamic environment such as the World Wide Web, where the collection and user search behavior change over time, regular evaluation of search engines with manual assessments is not feasible  ...  Imagine a web site consisting of 2 frames, one Abstract In this thesis we consider users' attempts to express their information needs through queries, or search requests and try to predict whether those  ...

2016 Proceedings of the 39th International ACM SIGIR conference on Research and Development in Information Retrieval - SIGIR '16  
Sponsored search represents a major source of revenue for web search engines.  ...  To address the large-scale nature of our problem, both in terms of data and vocabulary size, we propose a novel distributed algorithm for training of the embeddings.  ...  Request permissions from permissions@acm.org. there inevitably came the increase in its complexity, which left many users lost in the immense digital jungle of web content.  ...

S. Tata, J.S. Friedman, A. Swaroop
2006 22nd International Conference on Data Engineering (ICDE'06)  
In addition, the nature of the searches against these databases is also changing, and scientists today would like to ask more complex queries against these data sets.  ...  In fact, the very question might be ill-posed in the sense that different binding sites are likely to be effective to different extents, and therefore lead to different levels of activation (or repression  ...

Roger B. Dannenberg, William P. Birmingham, Bryan Pardo, Ning Hu, Colin Meek, George Tzanetakis
2007 Journal of the American Society for Information Science and Technology  
Many such systems have been built, but there has not been much useful evaluation and comparison in the literature due to the lack of shared databases and queries.  ...  Retrieval performance is very sensitive to distance functions and the representation of pitch and rhythm, which raises questions about some previously published conclusions.  ...  The opinions in this paper are solely those of the authors and do not necessarily reflect the opinions of the funding agency.  ...
