| Course description | The course deals with retrieval technologies behind search engines, such as Google. The course will aim to strike a balance between theoretical and system-related aspects of the field. The course will cover:
1. Theoretical aspects, including properties of text, queries, relevance, major retrieval models and evaluation;
2. System-related aspects, including crawlers, text processing, index construction and retrieval algorithms; and
3. Applications, including cross-language and multi-media search.
The same material will be covered in the level 10 and level 11 versions of the course. Level 11 students should expect more challenging assignments and an increased programming load. |

Assessment
There will be a final exam, contributing 70% of the course mark. The remaining 30% will be assessed through a combination of problem sets and programming exercises involving application of existing algorithms and evalution techniques. Compared to the level 10 version of this course, level 11 students will undertake more challenging assignments and an increased programming load. |

| Syllabus |
Lectures will cover the following topics, with a typical lecture integrating material from more than one aspect.
1. Theoretical aspects:
* The nature of text, Zipf and Heaps laws, clumping
* Information needs, queries and relevance
* Evaluation of retrieval systems
* Vector-space model and latent semantic indexing
* Probabilistic model and relevance feedback
* Language-modeling approaches
* Inference networks and structured queries
2. Systems aspects:
* Search engine architecture
* Crawling and feeds
* Text processing and representation
* Indexing methods and compression
* Distributed search and meta-search
* Presentation and visualization of search results
3. Applications:
* Web search
* Cross-language retrieval
* Multi-media retrieval
* Clustering and classification
* Topic detection and tracking
* Passage retrieval and question-answering
