Themes to which this unit belongs
  • Web and Distributed Systems


The representation, organisation, indexing, searching and exploitation of information, both by people and by information systems and software agents, have become central to knowledge-based economies, necessitating new approaches to information-intensive knowledge work. However, contemporary conventional information and communication technologies cannot adequately address information needs, especially where these imply finding (and possibly justifying) an answer through exploitation of different types of structured, semi-structured and unstructured information sources and different types of media, geographically dispersed. Humans suffer from information overload and information overlook. We have the technology to enable distributed computing and networking, but the bulk of visible information on the Web is oriented at humans and cannot easily be identified and exploited by systems. Information in the deep, hidden Web remains unexploitable in the general case. Social networking has blossomed but has frustrating limitations.

What are known as semantic technologies hold out the promise of improved flexible interaction of systems, improved search and the ability to offload tasks to quasi-independent software agents. In this vision, data now become smart data. The existence of smart data enables semantic search, capable of, for example, delivering precise results instead of thousands of documents to read. Smart data and semantic search enable interoperability of software systems: agents can discover resources and intercommunicate to achieve complex goals.

As these technologies are intimately linked with well-established techniques and ideas, to do with the indexing, classification and retrieval of information, and with more recent advances in large-scale processing of unstructured text, this unit also examines contributions from the fields of information retrieval and text mining.


To provide students with an understanding of principles, issues, techniques and solutions connected with advanced information retrieval.
To enable students to gain knowledge of how advances in distributed systems and the Web, studied on other course units, relate to innovative approaches to indexing, organising, finding and exploiting information using semantic technologies.
