Main speakers

Dr. Jim Jansen Pennsylvania State University, USA Jim Jansen ( is working on developing robust methods of data analysis that support the paradigm of log content as temporal information streams and provide predictive behaviors with reduced computational costs given the volume of data, acceptance of richer range of characteristics, and enhanced predictability modeling. Talk title: "Moving from Description to Prediction for Information Searching."

Dr. Fabrizio Silvestri ISTI-CNR, Italy Fabrizio Silvestri ( has been using query logs, in the past, mainly to improve efficiency of Web IR systems. He has been involved in designing a new caching policy (SDC) tailored on Web Search Engines workload. He has also designed a data partitioning and query routing technique for better exploiting the computing capacity of Web IR systems running large clusters of PCs. Recently he has started to work on using query logs to produce query shortcuts, i.e. suggesting queries that will reduce the length of user query sessions.

Dr. Lynn Connaway OCLC, USA Lynn Connaway ( has analysed transaction logs to identify discovery and access patterns demonstrated by users accessing the same database (WorldCat) through two different interfaces - First Search and WorldCat is the world's largest and most comprehensive bibliographic database, with 125 million records that represent more than 1.3 billion individual items in libraries worldwide. WorldCat is the underlying database for both FirstSearch and FirstSearch provides electronic access to dozens of databases and more than 10 million full-text and full-image articles while is the web-based interface for WorldCat. The discussion will include an analysis of behaviors and patterns revealed in FirstSearch and search logs as well as a comparison of the different search behaviors demonstrated in the two different interfaces of the data base. The log analyses suggest that users exhibit different behaviors and achieve different levels of success when using the different interfaces. The findings provide evidence-based information that can be used for the design and management of discovery and access tools. Talk title: "Following the Trail of WorldCat Users."  

Prof. Bettina Berendt Katholieke Universiteit Leuven, Belgium Bettina Berendt ( is a professor in the department of computer science at Katholieke Universiteit Leuven, Belgium. She obtained her habilitation in information systems from Humboldt University Berlin, Germany, and her Ph.D. in computer science/cognitive science from the University of Hamburg. Her research interests include Web and Social-Web mining, digital libraries, personalization and privacy, and information visualization. Bettina Berendt's work on Web log analysis has focussed on determining user interests by service-based log analysis, query mining, mining with background knowledge, and on investigating the impact of linguistic and cultural diversity on Web usage behaviour.

Prof. Nigel Ford University of Sheffield, UK Nigel Ford's ( main research focus is on the psychology of the web searcher, and he has conducted a number of studies of web searching to support learning. This work has entailed the analysis of query logs from searchers for whom personal data are known, such as gender, age, cognitive style, and study approach. He is particularly interested in using log analysis to identify associations between human individual differences, search patterns and effectiveness, the ultimate goal of which is to build user models capable of driving adaptive behaviour in search tools. Talk title: "Query log analysis and individual differences."

Dr. Thomas Mandl University of Hildesheim, Germany Thomas Mandl ( is organiser of a large-scale evaluation campaign called LogCLEF which is being run as part of the Cross Language Evaluation Forum (CLEF) 2009. He is interested in user behavior in information retrieval systems and social networks. The focus lies on user behavior in multilingual contexts. For future research, the relation between user studies and log analysis might open new perspectives. Thomas Mandl worked as a research assistant at the Social Science Information Centre in Bonn, Germany and as assistant professor at the University of Hildesheim in Germany where he is teaching in the programme International Information Management. He received a doctorate degree and a post doctoral degree (Habilitation) from the University of Hildesheim. His research interests include information retrieval, human-computer interaction and internationalization of information technology. Talk title "Query classification in Logfile-Analysis: Evaluation issues and user satisfaction."

Dr. Filip Radlinski Microsoft Research (Cambridge, UK) Filip Radlinski ( is an applied researcher at Microsoft Research in Cambridge, UK where he is in the Information Retrieval group and also works for Live Search. He completed his PhD in Computer Science on learning to rank from implicit feedback at Cornell University in 2008, advised by Thorsten Joachims. His research interests focus on the practical and theoretical challenges of learning to rank, and evaluating online ranked retrieval systems, using behavioural data recorded as people use such systems. He has used search log files to learn improved ranking functions, as well as to perform interactive evaluation of search systems. In particular, he has recently studied the relative power of various metrics that can be derived from log files for evaluating the differences between ranking functions.

Prof. Mark Levene Birbeck, University of London, UK The main focus of recent work in this area by Mark Levene ( has been on predicting users' navigation behaviour from server logs. Regarding query log analysis Mark has been working on query classification and applying this to topic specific analysis of query logs and for improving users' search experience.

Dr. Udo Kruschwitz University of Essex, UK The log analysis research by Udo Kruschwitz ( and colleagues focuses primarily on intranet collections. They have collected a query corpus of more than half a million queries submitted to a local search engine which is now being used as part of the AutoAdapt project to build adaptive domain models. They have also recently obtained funding for another KTP project with a major internet recruitment service where we will be analyzing substantial log files related to job search. Talk title: "Steps towards adaptive intranet search."

Dr. Vanessa Murdock Yahoo! (Barcelona, Spain) Vanessa Murdock ( is a research scientist at Yahoo! Research in Barcelona. Her work focuses on leveraging click data to improve the placement of sponsored search results and contextual advertising, and images. She received her PhD in 2006 from the University of Massachusetts where she worked with Bruce Croft at the Center for Intelligent Information Retrieval.

Dr. Giorgio Di Nunzio University of Padoa, Italy  Giorgio Maria Di Nunzio is co-organiser of the LogCLEF evaluation task which is being run as part of the Cross Language Evaluation Forum (CLEF) 2009. His main interest in the field of log analysis concerns knowledge extraction from different sources of data: Web logs, search logs and user studies, He has been involved in the analysis of the logs of The European Library ( since 2006. ( 

Dr. Dhavval Thakker Press Association, UK Dhavval Thakker ( is a KTP Research Associate working on “Intelligent Image Search Engine” project in partnership with Press Association Images and Nottingham Trent University. He received a doctorate degree from the Nottingham Trent University and an MSc degree from the Brunel University, UK. His present research interests are in the areas of Natural Language Processing & Semantic Web and their application in the image annotation and retrieval processes. In the query log analysis domain, he is mainly interested in search patterns and user behaviours in image search engine systems.

Nick Luft Manager of Content and Information Architecture, London. Nick Luft is the Manager of Content and Information Architecture for the Library at the Royal Institution of Chartered Surveyors (  His mission is to "construct a digital face for the library so that most of its stock and services are web-accessible." He is currently involved in a project to analyse data extracted from: (1) the RICS website's internal search-engine search logs; (2) the RICS library online catalogue's search logs; (3) the information about our visitors from our Google Analytics search log This analysis will mean that he can create a synonym and commonly misspelled searches list to configure the Google Search Application "query expansion" feature.
