Oggigiorno, a causa dell’aumento della quantità di dati memorizzati nei sistemi informativi, l'estrazione di conoscenza dai dati sta diventando sempre più complessa e difficile. Per far fronte a tali problemi, è stato introdotto un nuovo paradigma, chiamato OBDA (Ontology-Base Data Access). L'OBDA e’ basato sull'uso di tecniche di rappresentazione della conoscenza e di ragionamento automatico, per governare le risorse dei moderni sistemi di informazione, in cui l'ontologia è una descrizione formale di un dominio di interesse, specificato in una logica della famiglia DL-Lite di Logiche descrittive. In questo lavoro, diamo una breve panoramica dei sistemi OBDA, delle loro caratteristiche principali e in particolare presentiamo un noto sistema OBDA: MASTRO.

Abstract
Nowadays, due to the growing amount of data stored in the information systems, extracting knowledge from data is becoming more and more complex and difficult. To cope with such problem, a new paradigm has been introduced, which is called OBDA (Ontology-Base Data Access). OBDA is based on the use of knowledge representation and reasoning techniques, for governing the resources of modern information systems, in which, Ontology is a formal description of a domain of interest, specified in a logic of the DL-Lite family of Description Logics. In this work, we briefly will give an overview of OBDA systems, their main characteristics and in particular will present a well known OBDA system: MASTRO.File | Dimensione | Formato | |
