Research Interests

 

·  Knowledge Representation and Databases with statistic/probabilistic/uncertain information ,

·  Fuzzy/Probabilistic logic and Bayesian networks,

·  Modal  and Multi-valued Logics,

·  Semantic WEB and P2P systems,

·  Artificial Intelligence,

·  Category theory and Universal (co)Algebra.   (I developed a new Denotational semantic theory for a Relational database mappings based on Category monads and coalgebras ). 

Ph.D. (1994-1998):  in Computer Engineering , University of Rome "La Sapienza", Dept. Informatica e Sistemistica, Via Salaria 113, 00198 Roma, Italy

Thesis: Categories: Symmetry, n-dimensional levels and applications; 

Supervisor: Prof. Maurizio Lenzerini  

External reviewers:  Prof. Giuseppe Longo, Directeur de Recherche (DR1) CNRS & Département d'Informatique Ecole Normale Supérieure 45, rue d'Ulm , 75230 Paris   and    Prof. Sergei Soloviev, University of Durham (currently,    Institut de Recherche en Informatique de Toulouse ).

 

 

My  current research interests are in the following  areas:

  1. Event-based algebras for Databases, both theoretical and applied aspects.
  2. Semantics for Logic programming with uncertain/probabilistic information.
  3. Emergent intensional semantics for P2P database systems in Semantic WEB.
  4. Database Integration Systems, both theoretical and applied aspects. On the theoretical side, I am interested in architectures, generation Query-rewriting algorithms, many-valued semantics in order to manage incomplete and inconsistent information, and in Closed-world assumption for a Global database schema. On the applied side, I am interested in the costs and benefits of query-rewriting algorithms and how we can find application niches ( for example, Data intensive Peer-to-peer systems in Sematic Web) for this theory. One of my main interests is facilitating the building of reusable software modules for Data Integration Systems (as in Sewasie IST-2001-3485 Project).
  5. Intelligent interfaces enabling access to networks of complex database mappings, both theoretical (denotational semantics for a view-based database mappings) and applied aspects. 
  6. I am also interested in Graph-grammar language processing, Natural language semantics, Category-based characterizations of logic theory/models, non-monotonic logic, algebraic specifications and process algebras.
