Title
"Link sequential patterns to texts: to help for the interpretation and the exploitation of massive biological data"


Abstract

Transcriptomic technologies (the DNA chip technology) are very promising tools to identify new genes involved in cerebral ageing or in neurodegenerative diseases such as Alzheimer's. Unfortunately, these technologies produce massive biological data, which so far are extremely difficult to exploit. In this context, after a first step of data mining process which produces a list of sequential patterns, our objective is to ease experts. interpretation by allowing them to link the patterns to domain resources. We propose a process to query PubMed in order to obtain texts to define with the experts two types of analysis: validation (identification of the patterns which contain genes related in the texts) and research of innovations (identification of the patterns which contain genes that are linked in few texts or in recent texts).

Dr. Feirouz CHAKKOUR, teacher and reasercher in the Aleppo University in Syria, will be guest in our departement during september 2009 by a scholarship from Eramus Mundus program for academic staff.
