Question Answering systems that use local ontology as a knowledge source are trying to leverage deep linguistic and semantic analysis to understand the context of the natural language queries and to provide accurate answers. Automatic Ontology construction is an associated research area in Information System development. The Question Answering system framework proposed in this book introduces a novel knowledge management method called Concept Relational Ontology for developing a simple but reliable Question Answering system that uses very less NLP task and provides direct answer to the questions posed in natural languages.
