*"Information retrieval is the task of searching a body of information for objects that
statisfied an information need."*

This course is offered at the Faculty of Mathematics and Physics to graduate students interested in the area of information retrieval, web search, document classification, and other related areas. it is based on the book by Christopher D. Manning, Prabhakar Raghavan, Hinrich Schütze Introduction to Information Retrieval. The course covers both the foundations of information retrieval and some more advanced topics.

Deadline: Dec 31 23:59 100 points

Design, develop and evaluate your own retrieval system based on vectore space models.

Deadline: Jan 31 23:39 100 points

Design, develop and evaluate a state-of-the-art retrieval system using one of the off-the-shelf retrieval frameworks.

- There are two homework assignments during the semester.
- The assignments require a substantial amount of programming, experimentation, and reporting to complete.
- Students present their solutions during the practicals.
- The assignments are graded by 0-100 points each and are to be worked on independently.

- The exam is in a form of a written test, scheduled at the end of semester.
- The test include approximately 20 short-answer questions covered by the topics discussed during the course.
- Maximum duration of the test is 90 minutes.
- The test is graded by 0-100 points and is to be worked on independently.

- Both the homework assignments and exam are required to pass the course.
- Students are required to earn at least 50 points for each assignment and at least 50 points for the test.
- The final grade will be based on the average results of the exam and homework assignments weighted equally:
- 100% - 90%
- 89% - 70%
- 69% - 50%
- 0% - 50%

- No plagiarism will be tolerated.
- All cases of plagiarism will be reported to the Student Office.
