Recent work in Ontology learning and Text mining has mainly focused on engineering methods to solve practical problem. In this thesis, we investigate methods that can substantially...
The role of ontologies in knowledge base systems is gradually increasing. Along with the growth of Internet based applications and ecommerce, the need for easy interoperability bet...
We present a novel framework for learning to interpret and generate language using only perceptual context as supervision. We demonstrate its capabilities by developing a system t...
The adoption of the Internet technologies favors the diffusion of Web and Grid-based applications. However, the development of new applications exploiting the modern interfaces an...
Petri nets where, to my knowledge, the first theoretical model augmented with time constraints [Mer74], and the support of the first reachability algorithm of timed system [BM83, ...
