| Summary | 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. |
| Course description |
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 models or Relevance models
2. Systems aspects:
* Search engine architecture
* Crawling and content extraction
* Text processing and representation
* Indexing methods and compression
* Distributed search and meta-search
* Dealing with vocabulary mismatch
* Duplicate detection
