Previous registration on a KTH course is mandatory, preferably on a course with mathematical content, since the course in some parts assumes mathematical maturity. Students who have passed the course LI116N will be given priority.

Students should obtain a library card from the KTH Library before starting the course. The first two stages of the course are identical with the course LI116N. Some parts of the course may be given in English.

Course literature is Manning, Christopher D., Raghavan, Prabhakar & Schütze, Hinrich (2008). Introduction to information retrieval. New York: Cambridge University Press.  (Complementary reading, optional: Croft, Metzler, Strohman. Search Engines: Information Retrieval in Practice.) Additional material, according to the content of the last stage of the course. The students may be requested to individually search for and retrieve relevant material for their own project.

If the course is discontinued, students may request to be examined during the following two academic years.

• INL1 - Assignment, 1.5 credits, grading scale: P, F
