Paper on teaching Web IR

In March I'll be presenting a paper entitled Teaching Web Information Retrieval to Undergraduates at SIGCSE 2010 in Milwaukee, WI. In this paper, I discuss how I built a curriculum for my search engine course and the types of projects I assigned. The first time I taught the course, students built a search engine from scratch. The second time, students modified the open source search engine Nutch. Teaching with Nutch turned out to be quite a challenge. If you want to know more, read my paper.
