    Abstract:
    The NewsStand system is an example application of a general framework that we are developing to enable people to search for information using a map query interface, where the information results from monitoring the output of over 8,000 RSS news sources and is available for retrieval within minutes of publication. The advantage of doing so is that a map, coupled with an ability to vary the zoom level at which it is viewed, provides an inherent granularity to the search process that facilitates an approximate search. This distinguishes it from today's prevalent keyword-based conventional search methods that provide a very limited facility for approximate searches which are realized primarily by permitting a match via use of a subset of the keywords. However, it is often the case that users do not have a firm grasp of which keyword to use, and thus would welcome the capability for the search to also take synonyms into account. In the case of queries to spatially-referenced data, the map query interface is a step in this direction as the act of pointing at a location (e.g., by the appropriate positioning of a pointing device) and making the interpretation of the precision of this positioning specification dependent on the zoom level is equivalent to permitting the use of spatial synonyms. The issues that arise in the design of such a system including the identification of words that correspond to geographic locations are discussed, and examples are provided of the utility of the approach (including an adaptation to Tweets resulting in the TwitterStand system), thereby representing a step forward in the emerging field of computational journalism.

    Biography:
    Hanan Samet is a Professor of Computer Science at the University of Maryland, College Park and is a member of the Institute for Computer Studies. He is also a member of the Computer Vision Laboratory at the Center for Automation Research where he leads a number of research projects on the use of hierarchical data structures for database applications involving spatial data. He has a Ph.D from Stanford University. His doctoral dissertation dealt with proving the correctness of translations of LISP programs which was the first work in translation validation. He is the author of the recent book "Foundations of Multidimensional and Metric Data Structures" published by Morgan-Kaufmann, San Francisco, CA, in 2006 http://www.mkp.com/multidimensional , an award winner in the 2006 best book in Computer and Information Science competition of the Professional and Scholarly Publishers (PSP) Group of the American Publishers Association (AAP), and of the first two books on spatial data structures titled "Design and Analysis of Spatial Data Structures" and "Applications of Spatial Data Structures: Computer Graphics, Image Processing and GIS" published by Addison-Wesley, Reading, MA, 1990. He is the Founding Editor-In-Chief of the ACM Transactions on Spatial Algorithms and System (TSAS), the founding chair of ACM SIGSPATIAL, a recipient of the 2009 UCGIS Research Award, 2011 ACM Paris Kanellakis Theory and Practice Award, the 2010 CMPS Board of Visitors Award at the University of Maryland, a Fellow of the ACM, IEEE, AAAS, and IAPR (International Association for Pattern Recognition), and an ACM Distinguished Speaker. He received best paper awards in the 2008 SIGMOD Conference and the 2008 SIGSPATIAL ACMGIS'08 Conference, and a best demo award at the 2011 SIGSPATIAL ACMGIS'11 Conference. His paper at the 2009 IEEE International Conference on Data Engineering (ICDE) was selected as one of the best papers for publication in the IEEE Transactions on Knowledge and Data Engineering.
