Abstract

The increasingly prominent new subset of Web pages, called 'blogs' differs from traditional Web pages both in characteristics and potential to applications. We explore three aspects of the blogistan: its overall scope and size, identification of emerging hot topics of discussion and link patterns, and implications both to blogs and applications such as search. Beyond blogs, we develop a general methodology of mining evolving networks and connections. The first part of our study is longitudinal-based on a five-week continuous fetch of a seed collection of nearly 10,000 blog URLs. The second part is based on a successive crawl of pages suspected to be blogs leading to a larger collection of several million URLs. The collection is examined for a variety of properties. We characterize blogs and study different facets of the link structure in blogs and its evolution over time, attributes of servers and domains that host many of the blogs including their IP addresses, and how blogs behave with respect to various HTTP/1.1 protocol issues. Inferences from our in-depth exploration are relevant to applications ranging from mining to hosting of blogs and other issues of relevance to the measurement community.
