Module description

Search engines have become the first entry point into a world of knowledge and they form an essential part of many modern computer applications. While much of the underlying principles have been developed over decades, the landscape in search engine technology has changed dramatically in recent years to deal with data sources magnitudes larger than ever before (the rise of `big data'). As a result of that new paradigms for storing, indexing and accessing information have emerged. This module will provide the essential foundations of information retrieval and equip the students with solid, applicable knowledge of state-of-the-art search technology.

Module aims

The aim of the module is to provide the essential foundations of information retrieval and equip the students with solid, applicable knowledge of state-of-the-art search technology.

Module learning outcomes

On completion of the module, students will be expected to be able to:

- Design and implement a standard information retrieval system
- Understand standard IR models and their merits and limitations
- Demonstrate practical knowledge of employing state-of-the-art open source software for IR
- Demonstrate an understanding of commonly used evaluation approaches in IR
- Understand advanced concepts of search applications such as personalisation, profiling and contextual search
