Elementary knowledge of machine learning, probability theory, linear algebra (vector spaces), and data structures is recommended.
Search engines, the internet and cheap powerful hardware have drastically changed the way humans deal with information. Whereas thirty years ago librarians were still classifying books and articles using subject codes, nowadays search technology has become ubiquitous on desktop computers and mobile devices. This course covers both the theory and practice of the field of Information Retrieval, with a focus on to textual content (the courses 4343AUDIO and 4343MMIRL focus on audiovisual content).
This course covers the following aspects:
1. How can we formalize search for information and how can we evaluate search systems?
2. Which document features (e.g. term statistics) could be used to associate a ‘meaning’ to a text?
3. How can we extend the notion of relevance by looking at context and learn from interaction?
4. How can these elements be combined to classify a text or to perform relevance ranking in order to build a search engine?
5. Which data structures and techniques are essential for computational efficiency?
6. Advanced topics such as personalization, recommender systems, learning to rank and responsible information retrieval
By the end of the course, the student should have a thorough understanding of:
the foundations of information retrieval models
the pros and cons of various query processing techniques
efficient data structures and complexity of search and indexing algorithms
technologies and relevance models for web search
evaluation methods for IR systems
reviewing a scientific information retrieval publication
In addition, the student should have some practical experience with information retrieval experiments.

Mode of instruction
- Lectures (2h / week)
- Homework (weekly): getting more acquainted with the new lecture material by small exercises, mostly taken from the course book.
- Practical group assignments: -Applying lecture concepts on real-world datasets (presentation and report) -Critical review of a recent IR research paper (presentation and report)
The course grade will be computed as follows:
- Homework (weekly exercises) – 10%
- Practical assignments – 20%
- Critical review – 10%
- Final online written exam (closed book) – 60%
The teacher will inform the students how the inspection of and follow-up discussion of the exams will take place.

Additional reading assignments may be added as the course progresses, and will be made available through Brightspace.
