I tried to create the ontology for the blood cancer using the text data .There are lots of keywords which were manually searched and on the basis of that i build the ontology manually then after i built the ontology with the help of automated tool ,Text2Onto and GATE and compared the results I explained all that procedure and results inside the book and also there are some limitation which need to be overcome.I am working on those limitation and in my next edition i will try to optimize the solution.
