Graph conductance search Rich connections between random walks, graph eigensystems, and electrical networks make it attractive to apply them for ranking nodes. PageRank is a prominent example of the paradigm. In PageRank, the edge weights are fixed and we have to compute steady state probabilities of nodes. What if we have something like the opposite problem? And how to make this fast at query time? Supported by IBM and Microsoft , The effect of search engines on the Web graph and page popularity Search engines are influenced by the in degree of Web pages, but their ranked lists modulate page popularity and eventually their in degree, setting up a feedback to some degree.
Might the evolution of the Web graph be influenced substantially by the existence of search engines? Is there a need to regulate monopolies?
What are healthy economic objectives, and how to optimize them? Focused crawlers to build topic-specific portals A focused crawler collects a topic-specific subgraph of the Web by coupling classifiers and reinforcement learners with crawlers. An open-source focused crawler project was started at the Lab. Mining hypertext to estimate topics and popularity I built a hypertext classifier that uses the text in and links around a given Web page to label it with a topic. This was an early application of Markov networks to Web analysis.
As a member of the IBM Clever Project , I worked on algorithms to analyze the links around a web page and the text in pages that cite the given page to assign it a measure of popularity. Compiling and running parallel scientific programs In a previous life, my PhD thesis was on the design and implementation of compilers and runtime systems for distributed memory multiprocessors.

Description Mining the Web: Discovering Knowledge from Hypertext Data is the first book devoted entirely to techniques for producing knowledge from the vast body of unstructured Web data.
Building on an initial survey of infrastructural issues—including Web crawling and indexing—Chakrabarti examines low-level machine learning techniques as they relate specifically to the challenges of Web mining.
