IR Courses Updated

I updated my list of recent search (IR) graduate classes.

Recent Graduate Classes in Information Retrieval

I added a new class by Brian Davison he taught this past Spring:

CSE345/445 (Spring 2007) - WWW Search Engines Algorithms, Architectures and Implementations by Brian Davison at Lehigh University. Brian is one of the creators of DiscoWeb, later to become Teoma which was acquired by Ask. He also chairs the AIRWeb (Spam) workshop.

Of particular interest is the guest lecture by Marc Najork from Microsoft research on the effectiveness of link analysis algorithms, Comparing the Effectiveness of Different Scoring Functions for Web Search. Marc also presented the research this past week at SIGIR, HITS on the Web: How does it Compare?. His interesting conclusion is that when combined with the BM25F scoring algorithm a simple inter-domain in-link count is more effective than the default PageRank algorithm and just as effective as the expensive HITS algorithm. It's interesting to see such a simple algorithm prevail here when Google continuously toughts PageRank.
