This is the course website for CS 4780: Information Retrieval.
In this course, we will start with the basics of modern search engine architecture, and then focus on exploring the cutting-edge solutions in information retrieval problems, including query understanding, mining and modeling search activities, interactive search, mobile search, learning to rank, user interaction based evaluation, question answering, privacy, recommendation, and personalization.
We will use Introduction to Information Retrieval as our text book. But as this is a fast emerging field, new research problems and solutions come up everyday, most of our time should be spent on the latest publications in the community of information retrieval, including conferences of SIGIR, CIKM, WWW and WSDM, and journals of TOIS and Information Retrieval Journal.
Formula for being successful in this course: read more papers, ask more questions, and challenge what you have been told!
