A Language for Inconsistency-Tolerant Ontology Mapping.Ontology alignment plays a key role in enabling interoperability among various data sources present in the web.The nature of the world is such, that the same concepts differ in meaning, often so slightly, which makes it difficult to relate these concepts.It is the omni-present heterogeneity that is at the core of the web.The research work presented in this dissertation, is driven by the goal of providing a robust ontology alignment language for the semantic web, as we show that description logics based alignment languages are not suitable for aligning ontologies.The adoption of the semantic web technologies has been consistently on the rise over the past decade, and it continues to show promise.The core component of the semantic web is the set of knowledge representation languages -mainly the W3C 1 standards Web Ontology Language (OWL), Resource Description Framework (RDF), and Rule Interchange Format (RIF).While these languages have been designed in order to be suitable for the openness and extensibility of the web, they lack certain features which we try to address in this dissertation.One such missing component is the lack of non-monotonic features, in the knowledge representation languages, that enable us to perform common sense reasoning.For example, OWL supports the open world assumption (OWA), which means that knowledge about everything is assumed to be possibly incomplete at any point of time.However, experience has shown that there are situations that require us to assume that I was lucky to have the support of so many great people throughout the pursuit of my Ph.D. First of all, I would like to thank my advisor, Dr. Pascal Hitzler, who gave me the opportunity to pursue my Ph.D. under his guidance.I do not have enough words to describe his greatness as an advisor and, more importantly, as a person.It has been a great learning opportunity to work with him.A special appreciation goes to my dissertation committee members, Dr. Krishnaprasad Thirunarayan, Dr. Prabhaker Mateti, and Dr. Krzysztof Janowicz, for their valuable comments and suggestions to improve this dissertation.My family has been a great support and source of encouragement throughout this endeavor
