Abstract
Vast growth of biomedical databases has increased most of the researchers focus on the field of Text Mining. The documents appear in unstructured format. To process and discover knowledge from these data, the unstructured databases must be converted to structured format. For this task Text mining plays a vital role. Text preprocessing is an essential step in text mining. The common preprocessing tasks in text mining are Tokenizing, Removing Stop words and Stemming. In this paper we have discussed the implementation steps we have done on PubMed abstract using Rapidminer.
