The Web has transformed the way new scholars are introduced to their domains via timely access to its literature. However, once that literature has been accessed, there is not as much support for carrying out analytical tasks such as determining the rhetorical stance of a
particular author in the scholarly domain. This paper presents work on an ontology-based approach to representing scholarly knowledge in order to support such analytical work. Here we describe how diverse research into argumentation, knowledge organization, and communities of practice has been used to ground the design of an ontology that enables novel kinds of services to be developed.

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.
