KMi Seminars
Information Retrieval and Quantum Theory
This event took place on Wednesday 16 July 2008 at 11:30

 
Guido Zuccon

In this talk I will illustrate how Quantum Theory can be used to model Information Retrieval. In particular, I will briefly illustrate some previous work in this area, such the ones by van Rijsbergen ("The Geometry of Information Retrieval", CUP 2004) and Melucci ("A basis for Information Retrieval in Context", TOIS June 2008). Then I will describe how a technique for IR based on Logical Imaging can be formalized in terms of Quantum Theory: part of the work that I am going to introduce will be presented at TIR2008 in a paper titled "A formalization of Logical Imaging for Information Retrieval using Quantum Theory". Finally, I'm going to illustrate the ideas I planned to investigate during my visit to KMi.

Semantic Web and Knowledge Services
"The Semantic Web is an extension of the current web in which information is given well-defined meaning, better enabling computers and people to work in cooperation" (Berners-Lee et al., 2001).

Our research in the Semantic Web area looks at the potentials of fusing together advances in a range of disciplines, and applying them in a systemic way to simplify the development of intelligent, knowledge-based web services and to facilitate human access and use of knowledge available on the web. For instance, we are exploring ways in which tnatural language interfaces can be used to facilitate access to data distributed over different repositories. We are also developing infrastructures to support rapid development and deployment of semantic web services, which can be used to create web applications on-the-fly. We are also investigating ways in which semantic technology can support learning on the web, through a combination of knowledge representation support, pedagogical theories and intelligent content aggregation mechanisms. Finally, we are also investigating the Semantic Web itself as a domain of analysis and performing large scale empirical studies to uncover data about the concrete epistemologies which can be found on the Semantic Web. This exciting new area of research gives us concrete insights on the different conceptualizations that are present on the Semantic Web by giving us the possibility to discover which are the most common viewpoints, which viewpoints are mutually inconsistent, to what extent different models agree or disagree, etc...

Our aim is to be at the forefront of both theoretical and practical developments on the Semantic Web not only by developing theories and models, but also by building concrete applications, for a variety of domains and user communities, including KMi and the Open University itself.
