Architectural Description of Dependable Software Systems
This event took place on Monday 24 April 2006 at 14:00

 
Dr Cristina Gacek University of Newcastle

The structure of a system is what enables it to generate the system's behaviour from the behaviour of its components. The architecture of a software system is an abstraction of the actual structure of that system. It should only be as complex as it needs to be while fostering the system's dependability ( i.e., the ability to deliver a service that users can justifiably trust).

Architecture description languages (ADLs) are used to describe software system architectures. They support communication among various stakeholders, as well as early analysis and feasibility studies of architectural design decisions.

In this talk I will discuss how ADLs currently address the means to attain dependability, namely fault prevention, fault tolerance, fault removal, and fault forecasting.

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.
