We have huge ware house of data in our medical institutions.\n
We have huge ware house of data in our medical institutions. a gigantic distributed database with hidden data held in individual hospitals, research centres, and institutes. Is access to these data useful? Yes. Ground-breaking discoveries can be made if researchers in medicine are exposed to data rich in diversity. Is access to these data easy? Yes and no. The sheer size of the data available is more than any one can handle. Semantic web technologies serve to provide us access to such data and make good use of such data.\n
