Knowledgebases can become an effective tool essentially raising quality of information retrieval in molecular biology, promoting the development of new methods of education and forecasting of the biomedical R&D. Knowledge-based technologies should induce "paradigm shift" in the life science due to integrative focusing of research groups towards the challenges of postgenomic era. This paper debates concept of the knowledgebase, which exploits web usage mining to personalize the access of molecular biologist to the Internet resources.
