Deliverables - D05 Preliminary Analysis of the Collected Data

We tried to collect and make publicly available on the web site the most reliable datasets for the Information Networks. At the moment we have 13 maps of Internet at the AS level and the largest Web crawl ever realized. On top of that we also collected and presented some examples of social networks like the actor movie dataset and the dataset of 13 years of citations between US patents. From the point of view of the biological networks we present the Protein Interaction Maps and the Food webs available in the literature. The last data set has been the subject of a paper accepted on Nature on the statistical properties of Food Webs. For the protein network we also found very interesting results. The status of this latter piece of research is a preprint since the delayed starting date of the Swiss node. An extensive analysis on these data sets is present in a series of publications on the most important international journals. Pastor-Satorras and Vespignani will present most of their analysis on the Internet case in their next book to be published by Cambridge University Press.
