چکیده
ii Acknowledgements I wish to thank my advisor Maurizio Lenzerini, who constantly guided me throughout my Ph.D. course. Without his support I could never have accomplished this work. I also want to thank Riccardo Rosati, who contributed to the achievement of several technical results provided in this thesis, and AndreaCaì ı which, together with Riccardo, has been my co-author on the papers presenting some of the contributions of this thesis. Part of the research has been carried out together with Thomas Eiter and Gianluigi Greco, during my staying at the Vienna University of Technology. I am grateful to them for the research work done together. A special thank goes to Diego Calvanese and Giuseppe De Giacomo for several fruitful and stimulating discussions we had together. I would like to thank all the people of the Dipartimento di Informatica e Sistemistica of the University of Rome " La Sapienza " , the members of the Ph.D. Committee at the Dipartimento di Informatica e Sistemistica, Thomas Either and Sergio Greco as external referees, Silvio Salza and Luigi Palopoli as internal referees, and all the people of which I enjoyed the company during my Ph.D. In particular, I want to express my gratitude my girlfriend Natalia, my parents Angelo and Giuliana, and my sister Teresa.

Model Based Test Case Generation From Natural Language Requirements And Inconsistency, Incompleteness Detection in Natural Language Using Model-Checking Approach
Natural language (NL) is any language that arises in an unpremeditated fashion as the result of the innate facility for language possessed by the human intellect. A natural language is typically used for communication, and may be spoken, signed/written. Natural language (NL) is still widely used for developing software requirements specifications or other artifacts created for documenting requi...
متن کاملOptimization Methods for Logic-based Query Answering from Inconsistent Data Integration Systems
Information integration systems providing the user with transparent access to heterogeneous data sources through a unified global view of all data, have emerged as a crucial issue in many application domains. This global view usually comprises integrity constraints which should be satisfied by the data retrieved from the sources. However, they might be often violated, and suitable approaches fo...
متن کاملA Distributional Semantics Approach for Selective Reasoning on Commonsense Graph Knowledge Bases
Tasks such as question answering and semantic search are dependent on the ability of querying & reasoning over large-scale commonsense knowledge bases (KBs). However, dealing with commonsense data demands coping with problems such as the increase in schema complexity, semantic inconsistency, incompleteness and scalability. This paper proposes a selective graph navigation mechanism based on a di...
متن کاملOn the Role of Integrity Constraints in Data Integration
We discuss the issue of dealing with integrity constraints over the global schema in data integration. On the one hand, integrity constraints can be used to extract more information from incomplete sources, similarly to the case of databases with incomplete information. On the other hand, integrity constraints raise the problem of dealing with the inconsistency of the whole system, due to contr...
متن کاملA Novel Type-2 Adaptive Neuro Fuzzy Inference System Classifier for Modelling Uncertainty in Prediction of Air Pollution Disaster (RESEARCH NOTE)
Type-2 fuzzy set theory is one of the most powerful tools for dealing with the uncertainty and imperfection in dynamic and complex environments. The applications of type-2 fuzzy sets and soft computing methods are rapidly emerging in the ecological fields such as air pollution and weather prediction. The air pollution problem is a major public health problem in many cities of the world. Predict...
