Prerequisites
Curiosity and motivation to retrieve information about information retrieval. Chapters 1--5 benefit from basic course on algorithms and data structures. Chapters 6--7 needs in addition linear algebra, vectors and dot products. For Chapters 11--13 basic probability notions are needed. Chapters 18--21 demand course in linear algebra, notions of matrix rank, eigenvalues and eigenvectors.
Course Enrolment Limitations
The course is also offered to the students of the fields other than those the course is directly associated with.

Course objectives
Main objectives of this course is to introduce principles of information retrieval and gat acquainted with algorithms for NLP-based text processing.
Learning outcomes
Students will understand document preprocessing, indexing, and querying done on up to a web scale (as Google does);understand principles and algorithms of NLP-based text preprocessing, text semantic filtering and classification, and web searching needed for information systems and digital library design.

Teaching methods
Student activities explicitly welcomed as a part of evaluation (10 pts). Mentoring rather than ex cathedra lectures: ``The flipped classroom is a pedagogical model in which the typical lecture and homework elements of a course are reversed.'' Students will be expected to come prepared by reading given materials in advance. Contact hours will be devoted to topically constrained discussion (during lecture hours) or by solving examples during exercises. This will respect individual learning speed and students' apriori knowledge. Questions on PV211 IS discussion forum are welcome especially before lectures.
Rich study materials are available: MOOC, materials on http://web.stanford.edu/class/cs276/, including the whole IIR book http://nlp.stanford.edu/IR-book/.
These teaching methods will be complemented by invited lectures of specialists from the IR community (researchers of Seznam, Facebook, RaRe Technologies, etc.).
Assessment methods
Evaluation is based on the system that motivates students for continuous work during semester and for active participation in the course.
Classification system is based on points achieved (100 pts). A student can get 50 pts during the term: 20 pts for each of two midterm tests, 10 pts for your activity during term (lectures or discussion forums,...), and 50 pts for the final test. Final written exam will consist of open exercises (30 pts, similar to midterm ones) and multiple choice questions (20 pts). In addition, one can get additional premium points based on activities during lectures, exercises (good answers) or negotiated related projects. Grading scale (adjustments based on ECTS suggestions) z/k[/E/D/C/B/A] corresponds approximately to 50/57/[64/71/78/85/92] points.
Dates of at least three terms of final exams will be announced via IS.muni.cz. One substitute midterm test will be held during the exam period for those officially excused at the study department.
