Is a Semantic Web Agent a Knowledge-Savvy Agent?
No full textThe issue of knowledge sharing has permeated the field of distributed AI and in particular, its successor, multiagent systems. Through the years, many research and engineering efforts have tackled the problem of encoding and sharing knowledge without the need for a single, centralized knowledge base. However, the emergence of modern computing paradigms such as distributed, open systems have highlighted the importance of sharing distributed and heterogeneous knowledge at a larger scale—possibly at the scale of the Internet. The very characteristics that define the Semantic Web—that is, dynamic, distributed, incomplete, and uncertain knowledge—suggest the need for autonomy in distributed software systems. Semantic Web research promises more than mere management of ontologies and data through the definition of machine-understandable languages. The openness and decentralization introduced by multiagent systems and service-oriented architectures give rise to new knowledge management models, for which we can’t make a priori assumptions about the type of interaction an agent or a service may be engaged in, and likewise about the message protocols and vocabulary used. We therefore discuss the problem of knowledge management for open multi-agent systems, and highlight a number of challenges relating to the exchange and evolution of knowledge in open environments, which pertinent to both the Semantic Web and Multi Agent System communities alike
Web Services from an Agent Perspective
No full textThe growth of automated services on the Web has facilitated the emergence of a new software development paradigm. This paradigm is based on the composition of disparate services to achieve large-scale, reusable solutions for diverse domains. Borrowing heavily from research in object-oriented software engineering and multiagent systems, the Web service paradigm supports the construction, publication, provision, integration, and utilization of course-grained, software services in open, heterogeneous environments. This article examines this Web service paradigm from an open multiagent systems perspective and contrasts the formally grounded, knowledge-centric view of agents with the pragmatic, declarative, bottom-up approach adopted by Web services
Terry Underwood
No full textDate:1948Terry Underwood arrived in the Northern Territory in 1968 and with her new husband moved to a new home at Riveren. Home consisted of a caravan, a bough shed, camp stove and a tent as the master bedroom. Together they transformed Riveren into a thriving cattle station.
Over a span of 30 years she has been involved in many projects which have included: producer/director of plays, talent quests and documentaries, along with appearances on TV and radio. She is also a patron to the Australian Outback Tourism Association and Northern Territory Fashion Awards. In 2005 Underwood was awarded the Medal of the Order of Australia in the General Division in Queen's Birthday 2005 Honours List for "service to the community, particularly through business and in promotional and cattle industry roles". In her autobiography 'In the middle of nowhere' Underwood captures the essence of her life "Riveren has captured our bodies, hearts and spirits. It lies within the heart of Australia. How privileged we are to call it home. Riveren is where I belong. I know it would not have worked anywhere else with anyone else. In the middle of nowhere has become my everywhere." (Underwood, 1998: 276).

Flexible Provisioning of Semantic Web Service Workflows using a QoS Ontology
No full textSemantic Web services allow applications to automatically discover and provision distributed services at runtime. However, when such services are offered by autonomous providers, as is common in large distributed systems, their behaviour is inherently non-deterministic and unreliable. To address this problem, we describe an OWL-S extension that allows services to be annotated with quantitative performance measures, and outline a flexible, decision-theoretic algorithm that uses this knowledge to provision services as part of complex workflows
Auction mechanisms for efficient advertisement selection on public display
No full textPublic electronic displays can be used as an advertising medium when space is a scarce resource, and it is desirable to expose many adverts to as wide an audience as possible. Although the efficiency of such advertising systems can be improved if the display is aware of the identity and interests of the audience, this knowledge is difficult to acquire when users are not actively interacting with the display. To this end, we present BluScreen, an intelligent public display, which selects and displays adverts in response to users detected in the audience. Here, users are identified and their advert viewing history tracked, by detecting any Bluetooth-enabled devices they are carrying (e.g. phones, PDAs, etc.). Within BluScreen we have implemented an agent system that utilises an auction-based marketplace to efficiently select adverts for the display, and deployed this within an installation in our Department. We demonstrate, by means of an empirical evaluation, that the performance of this auction-based mechanism when used with our proposed bidding strategy, efficiently selects the best adverts in response to the audience presence. We benchmarked our advertising method with two other commonly applied selection methods for displaying adverts on public displays; specifically the Round-Robin and the Random approaches. The results show that our auction-based approach, that utilised the novel use of Bluetooth detection, outperforms these two methods by up to 64%
