Fulvio Crivellaro and Gabriele Genovese discussed a thesis titled “µJena”, which focused on the design and development of an API for handling RDF and OWL ontologies on mobile devices (supervisor: Prof. Letizia Tanca, co-supervisor: Giorgio Orsi). The prototype is a reduced, lightweight porting of the Jena API. µJena is an open source project and anyone [...]

The goal of this work is the analysis and proposal of a query language suitable for SDR-Networks, oriented graphs representing concepts and relationships among them. Given a SDR-Network constituting the reference schema of a data source (or the result of the integration of several different data sources), it is necessary to be able to express [...]
The goal of this thesis is the design and realization of an integration strategy for SDR-Networks, following the one presented in [1,2], and adapting it to the requirements of the Context-ADDICT scenario.
The general view consists of an application scenario SDR-Network specifying the foreseen domain of the data sources, SDR_D, and a SDR-network extracted from a [...]
The goal of this thesis is the adoption of strategies defined for a relational scenario to support the semi-automatic derivation of context-aware views for a Context-ADDICT scenario based on the SDR-Network model .
An SDR-Network is used to represent the concepts and their relations with respect to a given application scenario.
A Context Dimension Tree (CDT) [...]
In December Luca Macagnino discussed a thesis titled “Ontology extraction from relational Databases based on semantics” (Estrazione di Ontologie da Basi di Dati Relazionali basata sulla Semantica); supervisor is Letizia Tanca, co-supervisor are Carlo Curino and Antonio Penta.

In October Giorgio Orsi graduated, defending a thesis on Data Integration; supervisor is Letizia Tanca, co-supervisor is Carlo Curino.
Interoperability among automatic systems is a well known problem, especially for information systems. After the â€™80s, the massive adoption of database systems inside organizations lead to the need to integrate different data
repositories with possibly incompatible data schemata. [...]
