Keynote SpeakerTo be or not be engaged: What is the question (to ask)?  Prof Mounia Lalmas, Scientist at Yahoo! Labs Barcelona

Abstract: In the online world, user engagement refers to the quality of the user experience that emphasizes the phenomena associated with wanting to use a web application longer and frequently. User engagement is a multifaceted, complex phenomenon, giving rise to a number of approaches for its measurement: self-reporting (e.g., questionnaires); observational methods (e.g., facial expression analysis, desktop actions); and web analytics using online behavior metrics. These methods represent various trade-offs between the scale of the data analyzed and the depth of understanding. For instance, surveys are hardly scalable but offer rich, qualitative insights, whereas click data can be collected on a large-scale but are more difficult to analyze. Still, the core research questions each type of measurement is able to answer are unclear. This talk will present various efforts aiming at combining approaches to measure engagement and seeking to provide insights into what questions to ask when measuring engagement. (This is work done in collaboration with Janette Lehmann, David Warnock, Ioannis Arapakis, Georges Dupret and many others at Yahoo! Labs.)

Biography: Mounia Lalmas is a scientist at Yahoo! Labs Barcelona, which she joined in January 2011. Prior to this, she held a Microsoft Research/RAEng Research Chair at the School of Computing Science, University of Glasgow. Before that, she was Professor of Information Retrieval at the Department of Computer Science at Queen Mary, University of London, which she joined in 1999 as a lecturer (aka assistant professor). From 2002 until 2007, she co-led the Evaluation Initiative for XML Retrieval (INEX), a large-scale project with over 80 participating organizations worldwide, which was responsible for defining the nature of XML retrieval, and how it should be evaluated. Her current research focuses on three main areas: user engagement, social media and aggregated search.

Invited Speaker: Alex Poulovassilis : Flexible Querying of Heterogeneous Graph Data

Abstract:  Large volumes of graph-structured data are becoming increasingly prevalent in a broad range of application domains. Graph-structured data differs from other data in its greater focus on the relationships between entities, regarding these relationships as important as the entities themselves. Query formulation and evaluation techniques are needed that assist users in querying complex, dynamic or irregular graph data, where users may lack full knowledge of its structure.

This talk will discuss the use of query approximation and query relaxation techniques within one integrated framework that aims to support flexible querying of heterogeneous graph data, e.g. RDF linked data. Our framework incorporates standard notions of query approximation based on edit distance and of query relaxation based on RDFS inference rules.  The query language we adopt comprises conjunctions of regular path queries, thus covering extensions proposed for SPARQL to allow for querying paths using regular expressions. The talk will discuss theoretical foundations, algorithms, prototype implementations, results from performance studies, and ongoing work.  

Biography: Alexandra Poulovassilis is Professor of Computer Science at Birkbeck and Co-Director of the London Knowledge Lab, a multidisciplinary research lab of Birkbeck and the Institute of Education that aims to explore the ways in which digital technologies and new media are shaping the future of knowledge and learning. Her research is motivated by the increasing volumes and varieties of digital information available, and the need to support users in finding the right information for their purposes and in combining and reconciling information from different sources. Her current research is in techniques for querying, integrating, visualising and personalising information, particularly as arising in learning environments, science and social science.
