Summary form only given. Development of modern complex systems such as aircraft would be impossible without detailed descriptive and predictive models, but models are little used in the development of collaboration technology. Can models of human collaboration provide a foundation for development of new and improved collaborative technologies? The author explores this issue by considering the potential...
Summary form only given. In 2020 collaborative working environments will be based on collaborative systems including both general collaborative infrastructures and specific applications for supporting human-centric ubiquitous collaboration. Ubiquitous collaboration (UC) means the use of collaboration services at any stage of our work activities. UC will make possible to collaborate with anyone, at...
Summary form only given. National Science Foundation (NSF) has a long-standing interest in protecting, enhancing and evaluating information security, privacy and confidentiality in information systems. The interest is broad including new architectures, algorithms, data collection and evaluation methods. All these are in recognition of newly emerging environments and applications (e.g. pervasive computing,...
Summary form only given. As part the globalization trend, enterprises are facing a serious challenge of needing to be globally consistent and locally nimble at the same time. Recent rapid evolution of Web 2.0 and real-time event driven architecture served as the catalyst for new paradigms in enterprise information composition, and potentially enable much more flexible real-time global collaboration...
The theme of this research is mobile transaction processing systems, focusing on versatile data sharing mechanisms in volatile mobile environments. The rapid growth of wireless network technologies and portable computing devices has promoted a new mobile working environment. A mobile environment is different from the traditional distributed environment due to its unique characteristics: the mobility...
Collaborative online encyclopedias such as Wikipedia and PlanetMath are becoming increasingly popular. In order to understand an article in a corpus a user must understand the related and underlying concepts through linked articles. In this paper, we introduce NNexus, a generalization of the automatic linking component of PlanetMath.org and the first system that automates the process of linking encyclopedia...
No one knows how he or she will act in an emergency, but without proper preparations, it's a safe bet things won't go as well as they could! This is particularly true for people with PDDs. Consider...the tendency to obsess on a situation, can be a very devastating thing if the situation is a disastrous one. The inability to deal with sudden change can render an Aspietrade unable to react as quickly...
Computer supported collaborative work (CSCW) has typically been bound within organizations. Groupware applications are designed with organizational structures in mind, in a top-down approach that predicts communication and collaboration interactions between people. With Internet adoption in society, CSCW overflows organizational borders towards Internet supported collaborative work (ISCW), where the...
Collaboration has been identified as an important aspect in information seeking. People meet to discuss and share ideas and through this interaction an information need is quite often identified. However the process of resolving this information need, through interacting with a search engine and performing a search task, is still an individual activity. We propose an environment which allows users...
The usage of ontologies to develop a semantically rich experiment models promises to be a key advantage of scientific applications over earlier alternatives. Whilst it is often recognized that information gathered for the ontology modeling process can describe naturally the scientific knowledge and can be used for interoperation among heterogeneous systems (by establishing a global schema, for instance),...
This paper presents results of a survey, related to the theoretical task-technology-fitness framework. The survey was conducted in a large Oil and Gas company in Norway, namely Statoil ASA. The task-technology-fitness framework indicates which groups of medium or technology are appropriate to choose according to the task to be performed, when collaborating with others. We have here presented the extended...
This paper presents the idea of Web service interface syndication - a scheme for the collaborative creation of overlay networks based on common Web service interfaces. Rather than requiring complex management of dynamic peers we picture a setting of interconnected static Web applications forming syndicates and offering services in a self-organized fashion. Among other application scenarios, this paper...
Triple space computing is an emerging technology for communication and coordination of different semantic technologies. It has been achieved by extending tuple space computing to support RDF as triple space computing. It can play an important role by acting as global middleware providing support for collaboration of different semantic technologies. Several participants from semantic Web and semantic...
For collaborative environments to be successful, a fundamental requirement is that they provide support for inter-referential awareness - or the ability for one participant to refer to a set of objects, and for that reference to be understood by others. Participants in co-located collaboration benefit from the availability of non-verbal communication, including gestures, eye gaze and body movements...
The impact of information and communication technologies (ICT) has gained its prominence in several areas such as business and education. More concretely, during the last years it has been developed several tools and platforms so as to enrich the way of learning. Projects as NETCOIL and ECOSPACE study the way of establishing interoperation between different tools. More concretely, this paper analyzes...
This paper proposes the creation of an architectural layer for integration of all the resources and members participating in a given collaborative activity into a unified framework which is referred as the collaborative environment integration layer (CEIL). This layer is considered a necessary step for integrating with open standards all the collaborative resources or components into a tightly coupled...
Building a collaborative application from scratch is a hard task. In the last decade many advances have been made to help the developers to construct collaborative applications, however little effort has been made to extend existing single-user applications to support real-time collaboration. This work presents a mapping from the main components of an existing single-user model-view-controller based...
In order to allow the development of joint degrees through heterogeneous e-learning systems, we propose a federation services architecture whose implementation will be based on Web services. Our main objective is to allow e-learning systems to be able to work in a collaborative way; combining their data and functionality through the integration of their services. These services will be combined and...
Constraints are very useful in real-time collaborative editing systems. They are able to automatically enforce semantic rules and properties. A specific type of constraint is dataflow constraint. Any property that can be expressed as an equation can be represented as a dataflow constraint. However, ensuring multi-way dataflow constraint satisfaction and consistency maintenance in a replicated collaborative...
The development of collaborative multimedia applications today follows a vertical development approach, which is a major inhibitor that drives up the cost of development and slows down the pace of innovation of new generations of collaborative applications. In this paper, we propose a network communication broker (NCB) that provides a unified higher-level abstraction that encapsulates the complexity...
