Abstract: One of the major challenges in the post-genomic era is the improvemnt of the capability to recognize the disease related molecular targets. Even if the new experimental methods have greatly enhanced the analytical capability,the application of NLP (natural language processing) play a relevant role in the selection and extraction of relevant information. The published paper still constitute the main entry point to bridge togheter molcular biology, chemical and medical information. The text processing gives a great effort in the speed up the data warehousing. In this paper we present an interactive tool that allow to conceptually organize organize the Medline.
