Information exchange or information sharing means that people or other entities pass information from one to another. This could be done electronically or through certain systems. These are terms that can either refer to bidirectional information transfer in telecommunications and computer science or communication seen from a system-theoretic or information-theoretic point of view. As "information" in this context invariably refers to (electronic) data that encodes and represents the information at hand, a broader treatment can be found under data exchange. Information exchange has a long history in information technology. Traditional information sharing referred to one-to-one exchanges of data between a sender and receiver. Online information sharing gives useful data to businesses for future strategies based on online sharing. These information exchanges are implemented via dozens of open and proprietary protocols, message, and file formats. Electronic data interchange (EDI) is a successful implementation of commercial data exchanges that began in the late 1970s and remains in use today. Some controversy comes when discussing regulations regarding information exchange. Initiatives to standardize information sharing protocols include extensible markup language (XML), simple object access protocol (SOAP), and web services description language (WSDL). From the point of view of a computer scientist, the four primary information sharing design patterns are sharing information one-to-one, one-to-many, many-to-many, and many-to-one. Technologies to meet all four of these design patterns are evolving and include blogs, wikis, really simple syndication, tagging, and chat. One example of United States government's attempt to implement one of these design patterns (one to one) is the National Information Exchange Model (NIEM). One-to-one exchange models fall short of supporting all of the required design patterns needed to fully implement data exploitation technology.

Enjeux Mondiaux - Communication

The Communication A module of the course on Global Issues tackles challenges related to instantaneous communication and social media. The interdisciplinary approach implemented integrates SHS and engi

During the last decade, the scientific community has witnessed an unprecedented deployment of large-scale, federated e-Infrastructures such as Grid Computing, primarily for supporting data-intensive scientific exploration and coordinated problem solving. However, practical experience and user studies have indicated that the adoption of such e-Infrastructures is lagging behind original expectations, a fact which is mainly attributed to the limited support that available tools provide for user collaboration and information sharing. The goal of this paper is twofold, first to lay down the foundations for building a collaboration environment in the form of abstractions and second to show the effectiveness of these abstractions through g-Social, an Eclipse-based, open-source environment as an extension to g-Eclipse, that provides a powerful, user-friendly, platform-independent toolset for users, application developers and administrators of Grid infrastructures. g-Social enables user collaboration and resource sharing through Online Social Networking services, capitalizing on the success that these services have.

Personalized information access in a wiki using structured tagging

Karl Aberer, Akshay Kiran Singh

Environmental engineers from different organizations work in interdisciplinary projects having the need of information exchange. In particular, a collaborative environment with personalized access to information is needed, which supports strongly varying information needs of the users. This scenario is not fully supported by existing systems. For example, content management systems do not support personalized access to content. Social bookmarking systems are not sufficiently specific in user groups, thus, they miss context information of the bookmarks and introduce imprecision and noise. In this paper we propose to combine a collaborative content management system (wiki) with the social bookmarking idea. To improve the reuse of bookmarks, we represent additional context information in the form of structured tags.
