Decanato - Facoltà di scienze informatiche
Data d'inizio: 8 Settembre 2009
Data di fine: 9 Settembre 2009
The Faculty of Informatics is pleased to announce a seminar given by Leif Azzopardi
DATE: Tuesday, September 8th, 2009
PLACE: USI Università della Svizzera italiana, room SI-008, Informatics building (Via G. Buffi 13)
In this talk, I will introduce the concept of accessibility from the field of transportation planning, and explain how it can be adopted within the context of Information Retrieval (IR). An analogy is drawn between the two fields, which motivates the development of document accessibility measures for IR systems. Considering the accessibility/retrievability of documents within a collection given an IR System provides a different perspective on the analysis and evaluation of such systems. In an example application of these new measures, we show how they can be used to inform the design and management of current and future IR systems.
Dr. Leif Azzopardi is currently an RCUK Research Fellow within the Glasgow Information Retrieval Group and a full time academic member of staff within the Department of Computing Science, at the University of Glasgow.
He currently supervises several PhD and MSc Students on projects in ranging from traditional formal models based research and applications of Information Retrieval to extreme models, methods and applications (such as those based on Quantum Theory or Transportation Planning).
His research interests include: distributed information retrieval models and systems, formal models, specifically probabilistic models such as the Language Model, or Convergence to Order Framework, and the Evaluation of Information Retrieval Systems. More recently, he has began to develop the idea of "Accessibility" from Transportation Planning to the management and evaluation of Information Retrieval Systems.
Previously, Dr Azzopardi was a Post Doctoral Researcher within iLab at the University of Strathclyde in 2006, and ILPS at the University of Amsterdam in 2005. He received his Ph.D. in Computer Science from the University of Paisley in 2005, where he was supervised by Prof. Mark Girolami, Prof. Malcolm Crowe and Prof. Keith van Rijsbergen. Prior to this he received First Class Honours Degree in Information Science from the University of Newcastle, Australia, 2001. He was also the past Chair of the BCS Information Retrieval Specialist Group (2006-2008).
