Empowering cultural heritage professionals with tools for authoring and deploying personalised visitor experiences

This paper presents an authoring environment, which supports cultural heritage professionals in the process of creating and deploying a wide range of different personalised interactive experiences that combine the physical (objects, collection and spaces) and the digital (multimedia content). It is based on a novel flexible formalism that represents the content and the context as independent from one another and allows recombining them in multiple ways thus generating many different interactions from the same elements. The authoring environment was developed in a co-design process with heritage stakeholders and addresses the composition of the content, the definition of the personalisation, and the deployment on a physical configuration of bespoke devices. To simplify the editing while maintaining a powerful representation, the complex creation process is deconstructed into a limited number of elements and phases, including aspects to control personalisation both in content and in interaction. The user interface also includes examples of installations for inspiration and as a means for learning what is possible and how to do it. Throughout the paper, installations in public exhibitions are used to illustrate our points and what our authoring environment can produce. The expressiveness of the formalism and the variety of interactive experiences that could be created was assessed via a range of laboratory tests, while a user-centred evaluation with over 40 cultural heritage professionals assessed whether they feel confident in directly controlling personalisation

MPICH-G2: A Grid-Enabled Implementation of the Message Passing Interface

Application development for distributed computing "Grids" can benefit from tools that variously hide or enable application-level management of critical aspects of the heterogeneous environment. As part of an investigation of these issues, we have developed MPICH-G2, a Grid-enabled implementation of the Message Passing Interface (MPI) that allows a user to run MPI programs across multiple computers, at the same or different sites, using the same commands that would be used on a parallel computer. This library extends the Argonne MPICH implementation of MPI to use services provided by the Globus Toolkit for authentication, authorization, resource allocation, executable staging, and I/O, as well as for process creation, monitoring, and control. Various performance-critical operations, including startup and collective operations, are configured to exploit network topology information. The library also exploits MPI constructs for performance management; for example, the MPI communicator construct is used for application-level discovery of, and adaptation to, both network topology and network quality-of-service mechanisms. We describe the MPICH-G2 design and implementation, present performance results, and review application experiences, including record-setting distributed simulations.Comment: 20 pages, 8 figure

ODESeW for the creation of R&D projects’ Intranets and Extranets

In this paper, we describe how the ODESeW platform can be used for the generation of the internal and external Web sites of R&D projects. ODESeW is a platform for the development of Semantic Web applications, which has been successfully used in the creation of the semantic portals of the EU R&D projects Esperonto, Knowledge Web and OntoGrid

MIRAI Architecture for Heterogeneous Network

One of the keywords that describe next-generation wireless communications is "seamless." As part of the e-Japan Plan promoted by the Japanese Government, the Multimedia Integrated Network by Radio Access Innovation project has as its goal the development of new technologies to enable seamless integration of various wireless access systems for practical use by 2005. This article describes a heterogeneous network architecture including a common tool, a common platform, and a common access. In particular, software-defined radio technologies are used to develop a multiservice user terminal to access different wireless networks. The common platform for various wireless networks is based on a wireless-supporting IPv6 network. A basic access network, separated from other wireless access networks, is used as a means for wireless system discovery, signaling, and paging. A proof-of-concept experimental demonstration system is available

The Affective Perceptual Model: Enhancing Communication Quality for Persons with PIMD

Methods for prolonged compassionate care for persons with Profound Intellectual and Multiple Disabilities (PIMD) require a rotating cast of import people in the subjects life in order to facilitate interaction with the external environment. As subjects continue to age, dependency on these people increases with complexity of communications while the quality of communication decreases. It is theorized that a machine learning (ML) system could replicate the attuning process and replace these people to promote independence. This thesis extends this idea to develop a conceptual and formal model and system prototype. The main contributions of this thesis are: (1) proposal of a conceptual and formal model for using machine learning to attune to unique communications from subjects with PIMD, (2) implementation of the system with both hardware and software components, and (3) modeling affect recognition in individuals based on the sensors from the hardware implementation

Exploring the Effectiveness of Social and Digital Media Communications on Organization-Public Relationship Building with Employees

More than a decade after the emergence of social and digital media, professional communicators increasingly use these channels to interact with a wide array of stakeholders. Simultaneously, public relations (PR) and communications leaders seek to understand whether their efforts to communicate and engage with stakeholders through these channels are effective in establishing and building relationships, as well as to measure “effectiveness” in the new technology-driven communications landscape. With this study, I addressed a gap in the academic research with regard to understanding the effectiveness of social and digital media as a communications tool by assessing employees’ perceptions of their organization with respect to five communication concepts, both in general and based specifically on the company’s social media communications. I assessed the relationship between the employee stakeholder and the organization from two viewpoints: first, from the viewpoint of the employees with whom the organization is communicating, and second, from the viewpoint of the communications professionals who post social and digital media messages on behalf of the organization. The results showed that an intervention to educate employees about the organization’s social and digital media communications did not result in employees’ increased positive perceptions of the organization as a whole or of the organization’s sites with regard to each of the five communications concepts. The increase in employees’ positive perceptions of the organization’s social and digital media sites, which reflected the communication concept “promoting communal relationships,” was significant at p \u3c .10; also, increases for three individual statements that were part of the communications concepts were sufficient for statistical significance. The intervention did result in statistically significant increases in employee use of social and digital media to engage with the organization and in usage of specifically LinkedIn to engage with the organization. The communicators who are responsible for the organization’s social and digital media communications generally held the same perceptions as other employees with regard to how the organization in general and its social media sites specifically fostered the five communication concepts.
