Software infrastructure and design challenges for ubiquitous computing applications

Striving to integrate computing into everyday activities in a seamless manner.

Towards High-Precision Service Retrieval

The ability to rapidly locate useful on-line services (e.g. software applications, software components, process models, or service organizations), as opposed to simply useful documents, is becoming increasingly critical in many domains. Current service retrieval technology is, however, notoriously prone to low precision. This paper describes a novel service retrieval approached based on the sophisticated use of process ontologies. Our preliminary evaluations suggest that this approach offers qualitatively higher retrieval precision than existing (keyword and table-based) approaches without sacrificing recall and computational tractability/scalability.

Challenges in Design and Software Infrastructure for Ubiquitous Computing Applications

Abstract In traditional computing environments, users actively choose to interact with computers. Ubiquitous computing applications are likely to be different—they will be embedded in the users physical environment and integrate seamlessly with their everyday tasks. This vision leads to a set of defining characteristics, requirements, and research challenges for ubiquitous applications. This chapter identifies some of the key characteristics via a scenario and derives the important application design and software infrastructure challenges that need to be addressed by the computing research community.

Towards adaptive workflow systems: CSCW-98 workshop report

The workshop Towards Adaptive Workflow System was organized by the authors of this report as part of the 1998 Conference on Computer Supported Collaborative Work (CSCW-98), and was held at the Westin Seattle on Saturday, November 14, 1998. The workshop had about 30 attendees and included invited presentations, paPer presentations/discussions and a panel. This report summarizes on the Goals and topics of the workshop, presents the major activities and summarizes some of the issues discussed during the workshop.
