Content and learning outcomes
Course contents
Basic and advanced technologies for information retrieval: information extraction; efficient text indexing; indexing of non-textual data; boolean models and vector space models for search; evaluation and user interface issues; the structure of Internet search engines.
Intended learning outcomes
On completion of the course, you should be able to:
* explain the concepts indexing, vocabulary, normalisation and dictionary in information retrieval,
* give an account of different distance measures for text and choose a distance measure that is appropriate for a given problem,
* define a boolean model and a vector space model and explain the difference between them,
* implement a method for ranked search of a very large number of documents with hyper links,
* evaluate information retrieval algorithms and give an account of difficulties with evaluation,
* give an account of the structure of an Internet search engine.
