Interrogazioni in linguaggio naturale a basi dati eterogenee: l'ontologia nel sistema "FuLL" nei GIS

The interaction between users and GIS software is a known and critical issue. The importance of giving those users a natural language interface to the system is thus strategic. Moving such a NL interface between heterogeneous DBs is an even more challenging task. We accomplish this by using a domain ontology as a knowledge repository and interface between raw data and language semantics. Successful tests of FuLL's (Fuzzy Logic and Language) technology are reported, where we have used the same ontology structure and connected it to Bologna's and Catania's district geo-databases.
