Personalized Web Services for Web Information Extraction
The field of information extraction from the Web emerged with the growth of
the Web and the multiplication of online data sources. This paper is an
analysis of information extraction methods. It presents a service oriented
approach for web information extraction considering both web data management
and extraction services. Then we propose an SOA based architecture to enhance
flexibility and on-the-fly modification of web extraction services. An
implementation of the proposed architecture is proposed on the middleware level
of Java Enterprise Edition (JEE) servers
Distributed control of reconfigurable mobile network agents for resource coordination
Includes abstract.Includes bibliographical references.Considering the tremendous growth of internet applications and network resource federation proposed towards future open access network (FOAN), the need to analyze the robustness of the classical signalling mechanisms across multiple network operators cannot be over-emphasized. It is envisaged, there will be additional challenges in meeting the bandwidth requirements and network management...The first objective of this project is to describe the networking environment based on the support for heterogeneity of network components..
Protecting the infrastructure: 3rd Australian information warfare & security conference 2002
The conference is hosted by the We-B Centre (working with a-business) in the School of Management Information System, the School of Computer & Information Sciences at Edith Cowan University. This year\u27s conference is being held at the Sheraton Perth Hotel in Adelaide Terrace, Perth. Papers for this conference have been written by a wide range of academics and industry specialists. We have attracted participation from both national and international authors and organisations.
The papers cover many topics, all within the field of information warfare and its applications, now and into the future.
The papers have been grouped into six streams:
âą Networks
âą IWAR Strategy
âą Security
âą Risk Management
âą Social/Education
âą Infrastructur
COMPONENT TECHNOLOGIES AND THEIR IMPACT UPON SOFTWARE DEVELOPMENT
Software development is beset with problems relating to development productivity, resulting in
projects delivered late and over budget. While the term software engineering was first introduced
in the late sixties, its current state reflects no other engineering discipline. Component-orientation
has been proposed as a technique to address the problems of development productivity and much
industrial literature extols the benefits of a component-oriented approach to software
development.
This research programme assesses the use of component technologies within industrial software
development. From this assessment, consideration is given to how organisations can best adopt
such techniques. Initial work focuses upon the nature of component-orientation, drawing from the
considerable body of industrial literature in the area. Conventional wisdom regarding componentorientation
is identified from the review. Academic literature relevant to the research programme
focuses upon knowledge regarding the assessment of software technologies and models for the
adoption of emergent technologies. The method pays particular attention to literature concerning
practitioner focussed research, in particular case studies. The application of the case study method
is demonstrated.
The study of two industrial software development projects enables an examination of specific
propositions related to the effect of using component technologies. Each case study is presented,
and the impact of component-orientation is each case is demonstrated. Theories regarding the
impact of component technologies upon software development are drawn from case study results.
These theories are validated through a survey of practitioners. This enabled further examination
of experience in component-based development and also understanding how developers learn
about the techniques.
A strategy for the transfer of research findings into organisational knowledge focuses upon the
packaging of previous experience in the use of component-orientation in such a way that it was
usable by other developers. This strategy returns to adoption theories in light of the research
findings and identifies a pattern-based approach as the most suitable for the research aims. A
pattern language, placed in the context of the research programme, is developed from this
strategy.
Research demonstrates that component-orientation undoubtedly does affect the development
process, and it is necessary to challenge conventional wisdom regarding their use. While
component-orientation provides the mechanisms for increased productivity in software
development, these benefits cannot be exploited without a sound knowledge base around the
domain
SMArc: a proposal for a smart, semantic middleware architecture focused on Smart City energy management
Among the main features that are intended to become part of what can be expected from the Smart City, one of them should be an improved energy management system, in order to benefit from a healthier relation with the environment, minimize energy expenses, and offer dynamic market opportunities. A Smart Grid seems like a very suitable infrastructure for this objective, as it guarantees a two-way information flow that will provide the means for energy management enhancement. However, to obtain all the required information, another entity must care about all the devices required to gather the data. What is more, this entity must consider the lifespan of the devices within the Smart Gridâwhen they are turned on and off or when new appliances are addedâalong with the services that devices are able to provide. This paper puts forward SMArcâan acronym for semantic middleware architectureâas a middleware proposal for the Smart Grid, so as to process the collected data and use it to insulate applications from the complexity of the metering facilities and guarantee that any change that may happen at these lower levels will be updated for future actions in the system
Self-Adaptive Communication for Collaborative Mobile Entities in ERCMS
International audienceAdaptation of communication is required for maintaining the connectivity and the quality of communication in group-wide collaborative activities. This becomes challenging to handle when considering mobile entities in a wireless environment, requiring responsiveness and availability of the communication system. We address these challenges in the context of the ROSACE project where mobile ground and flying robots have to collaborate with each other and with remote human and artificial actors to save and rescue in case of disasters such as forest fires. This paper aims to expose a communication component architecture allowing to manage a cooperative adaptation which is aware of the activity and resource context into pervasive environment. This allows to provide the appropriate adaptation of the activity in response to evolutions of the activity requirements and the changes in relation with the communication resource constraints. In this paper, we present a simulation of a ROSACE use case. The results show how ROSACE entities collaborate to maintain the connectivity and to enhance the quality of communications
