20 Credits AUTUMN

Aims/Description: Information Retrieval (IR) systems are ubiquitous as searching has become a part of everyday life. For example, we use IR systems when we search the Web, look for resources using a library catalogue or search for relevant information within organisational repositories (e.g. intranets). This module provides an introduction to the area of information retrieval and computerised techniques for organsing, storing and searching (mainly) textual information items. Techniques used in IR systems are related to, but distinct from, those used in databases. The emphasis for IR systems is to find documents that contain relevant information and separate these from a potentially vast set of non-relevant documents. The content of the module is grouped into two main areas: (1) fundamental concepts of IR (indexing, retrieval, ranking, user interaction and evaluation) and (2) applying IR in specific domains (Web, libraries and enterprises) and dealing with non-textual and non-English content (multimedia and multilingual IR).
