XML Retrieval
Definition of Innovative Clustering Techniques
User Profiles Definition
Information Quality (with Carlo Batini and Matteo

Personalization in IR
• Aims: to formally represent user preferences (by means of
ontological languages) and to exploit them in personalised IR
(and IF) processes (e.g. result diversification and query
reformulation)
• Researchers involved: Silvia Calegari, Celia da Costa Pereira
• International Cooperations: Susan Gauch (University of Arkansas)
and Lynda Tamine-Lechani, Mohand Boughanem (Paul Sabatier
University)
• Cooperation at DISCo: Davide Ciucci and Fabio Farina
• International affiliation: IEEE Task Force on Semantic Web
• Projects: Proposal Prin 2010
XML Retrieval
• Aims: to define an extesnion of the XPath query language for
specifying search contraints on both content and structure, and to
define efficient data structures to implement the retrieval process
• Researchers Involved : Emanuele Panzeri, Stefania Marrara
• International Cooperation: Nieves R. Brisaboa (University of La Coruna)
• Cooperation with Companies: IntelliSemantics Srl and Saes
Getters Group
• Projects: High Performance processing for large data sets represented as
Graphs (HIPERGRAPH) (Principal Investigator: Ricardo Baeza Yates –
Yahoo! Research)
Document Clustering
• Aim: definition of innovative techiniques of soft
hierarchical clustering, specifically designed for textual IR
applications.
• Key people: Giorgio Ghisalberti, Gloria Bordogna (IDPA, CNR)
• Collaborations: SeCo lead by Stefano Ceri at Politecnico di
Milano
Information Quality
• Aim: to define a unifying and formal framework for the
assessment of the quality of information (structured to
unstructured)
• Cooperation at DISCo: Carlo Batini, Matteo Palmonari
• External collaboration:Cinzia Cappiello, Politecnico di
Milano
Web Service Retrieval
• Aim: to define a semantic approach to the retrieval of Web
Services
• Cooperation at DISCo: Andrea Maurino, Matteo
Palmonari, Giuseppe Frisoni
• External collaboration:Francesco Guerra, Università di
Modena
