I have been interested in networks of all sorts: biological, social, physical, etc. A good example of social networks are weblogs, including Persian weblogs. In this case, each weblog is a node and each url link is a directional connection between two nodes. By studying this network, we can know about: the main people who propagate ideas in this network, whether there are clusters of people who talk between themselves without much connection to outside, or whether these clusters are centered around coherent ideas for example politics, erotica, etc. For the interest of physicists, we can also see if the number of links per node obeys a power law distribution, which then would be called a "scale free distribution."
For this purpose, I took the first step and wrote a perl script to find all the links between a given set of weblogs. My script searches through all the archives of old messages of each weblog as well. Unfortunately, this script does not work for weblogs on persianblog.com or blogsky.com sites, which are host to a considerable number of persian websites. Once I get around this problem, I will be able to obtain the network of Persian weblogs.
Please let me know your suggestions.
