Other useful books:
Search Engines: Information Retrieval in Practice by W. Bruce Croft, Donald Metzler, and Trevor Strohman. In particular, this has more about web search engines specifically (as opposed to information retrieval generally) than MRS.

Information Retrieval: Implementing and Evaluating Search Engines by Stefan Büttcher, Charles L.A. Clarke, and Gordon V. Cormack. Includes very in-depth discussion of data structures and algorithms for indexing.

Students with Disabilities

Academic accommodations are available for students with disabilities. Please contact the Moses Center for Students with Disabilities (212-998-4980 or mosescsd@nyu.edu) for further information. Students who are requesting academic accommodations are advised to reach out to the Moses Center as early as possible in the semester for assistance.

Cheating

You may discuss any of the assignments with your classmates (or anyone else) but all work for all assignments must be entirely your own. Any sharing or copying of assignments will be considered cheating. By the rules of the Graduate School of Arts and Science, I am required to report any incidents of cheating to the department. My policy is that the first incident of cheating will result in the student getting a grade of F for the course. The second incident, by GSAS rules, will result in expulsion from the University.
