Information and communication in Context
This event took place on Thursday 08 December 2005 at 11:00
Dr. Anne Adams University College London Interaction Centre
This presentation reviews both security and information resource studies that highlight the important theme of social and organisational context.
The first half of this talk reviews security in context. Studies are presented that highlight how context can change users perceptions of authentication and privacy. Physical location can change perceptions as can awareness and perceived control of virtual context. A model is presented which details how users' apparent cavalier attitude towards privacy can change when they realise that their contextual assumptions are inaccurate.
The second half of this talk reviews digital resources in context from digital libraries to the web. Findings are presented that detail how the web can be both perceived as an empowering tool and a threat to social structures. When the latter is the case this can result in computers locked behind doors to protect social order. Issues of information quality, awareness and accessibility are also reviewed.
Dr. Anne Adams is a Research Fellow at UCL Interaction Centre and a visiting Senior Lecturer at the Middlesex University 'Interaction Design Centre'. Her research reviews the social and organisational aspects of information and communication resources. Her research domains have ranged from academia to the health domain. Findings were not only published but also fed back to the information providers and designers in the development of their systems.
Dr Adams research into usability and security (i.e. authentication, privacy and trust) has concentrated on CSCW and multimedia communications. Recent publications and a Book chapter relate to these issues in both the academic and health domain.
She is a member of the ACM and has been on the committee for the British HCI group and has organised the Healthcare Digital Library workshop (at the European Conference for Digital libraries) for the past three years. She has presented at and chaired sessions at international conferences and been both an invited and keynote speaker for academic, industrial and health organisations across the world. This year she was an invited speaker at the 'Royal Society of Medicine', 'GOOGLE' in Palo Alto & 'Microsoft' whilst also winning the 'best international paper' at the IEEE ACM joint conference of digital libraries.

Multimedia and Information Systems is...
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.
