Title: " The Sensor Web: Noisy and Errorsome "
Lecturer: Professor Alan Smeaton, School of Computing, Dublin City University and CLARITY: Centre for Sensor Web Technologies
Abstract
Classical information retrieval is based around a user having an information need, formulated as a query, and a system which matches the query against 'documents', retrieving those most likely to be relevant. But what if the information we need or seek is not available from documents, either discrete or inter-connected, but needs to be taken from a constant stream of data values, namely data from sensors. These sensors cover the physical sensors around us (environment, place, physical activities like traffic, weather, people movement, crowd gatherings like concerts and sports events) as well as the online sensors we have access to (blogs, tweets, etc.). Often termed the *sensor web*, this information source is characterised as being noisy, errorsome, unpredictable and dynamic. In this presentation I introduce five very different sensor web applications that we have developed within CLARITY, to show the breadth and pervasive nature of the sensor web and I then show some of the techniques which we use to manage the information which forms part of the sensor web.
Biography
Since 1997, Alan Smeaton has been a Professor of Computing at Dublin City University where he has previously been Head of School and Dean of Faculty. His early research interests covered the application of natural language processing techniques to text-based information retrieval but this then broadened to cover the indexing and content-based retrieval of information in all media, text, image, audio and especially digital video. He is now the deputy director of the CLARITY centre for Sensor Web Technologies; CLARITY is a partnership between University College Dublin, Dublin City University and Tyndall National Institute (TNI) Cork.. The focus of his work now is in information access for human digital memory applications, applications of the sensor web, and benchmarking content-based video applications. Alan Smeaton is the co-founder and a coordinator of TRECVid which, since 2001, has grown to be the largest worldwide multimedia benchmarking activity with about 80 participating research centres each year. In terms of conference organisation, Alan was host of SIGIR in Dublin (1994), co-chair of SIGIR (2003), co-chair or ICME (2005), co-chair of MMM (2009), host of ESSIR (2005) and general chair of CIVR in Dublin (2004). He has published over 300 refereed publications, was an Associate Editor of the ACM Transactions on Information Systems for 8 years and previously a member of the Editorial Board of Information Retrieval, and currently a member of the boards for Information Processing and Management, Foundations and Trends in Information Retrieval, the ACM Journal on Computers and Cultural Heritage and of the Journal on Digital Libraries. He has graduated over 30 M.Sc. and PhD research students and has acted as external examiner for PhD theses on more than 30 occasions. He has assisted the European Commission as an evaluator or reviewer in the ESPRIT, LRE, Language Engineering, Information Engineering, MLAP, LTR, INCO-Copernicus and IST FP5, FP6 and FP7 programmes as well as acting as a project reviewer for many specific projects. In 2002 Alan Smeaton was awarded the DCU President's award for "outstanding research carried out in the field of Science and Engineering" and in 2009 was awarded the DCU Educational Trust Leadership Circle award.
