This paper describes the application of the Activity Theory framework to the analysis of work practices in an organisation, to inform the design of a computer system for supporting collaborative learning in the workplace. A study involving the analysis of an organisation and using Engestrsm's expanded triangle model of human activity [5] is described. A methodology developed during the study for breaking down the extended triangle and applying it is given, together with practical examples. The paper concludes by highlighting strengths and weaknesses of the model, and suggests a number of refinements for its practical application.

Multimedia and Information Systems
Our research is centred around the theme of Multimedia Information Retrieval, ie, Video Search Engines, Image Databases, Spoken Document Retrieval, Music Retrieval, Query Languages and Query Mediation.

We focus on content-based information retrieval over a wide range of data spanning form unstructured text and unlabelled images over spoken documents and music to videos. This encompasses the modelling of human perception of relevance and similarity, the learning from user actions and the up-to-date presentation of information. Currently we are building a research version of an integrated multimedia information retrieval system MIR to be used as a research prototype. We aim for a system that understands the user's information need and successfully links it to the appropriate information sources, be it a report or a TV news clip. This work is guided by the vision that an automated knowledge extraction system ultimately empowers people making efficient use of information sources without the burden of filing data into specialised databases.
