Thesis: “µJena”

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 [1].

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 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 ’80s, the massive adoption of database systems inside organizations lead to the need to integrate different data
repositories with possibly incompatible data schemata. [...]
