Database & Knowledge Based Approaches to Information Retrieval; A Comparative Study

I wish to acknowledge the people who inspired me to believe that a machine can have intelligence. They are the ones who envisioned the future of mankind. I specially appreciate to my advisor Dr. Srivasan raghunathan, who was always supportive and encouraged to finish this research. I also sincerely thank for my parents who are always concerned of my well-being. Without them, what I achived here cannot be possible.
