Colloquium - Anderson

Pervasive Hypermedia
University of California, Irvine

The heterogeneity of modern computing environments presents users with an overwhelming number of implicit relationships between information resources, applications, and documents. These relationships are difficult to manage and constantly changing, challenging even the most technically-adept users. However these difficulties can be overcome: given proper tools and organizational principles, users may be able to capture a significant amount of these relationships explicitly and ease the task of their management.

Hypermedia is an approach to addressing environment-wide heterogeneity that provides users with the necessary abstractions (and associated tools) for organizing and capturing the relationships important to them. Open hypermedia systems represent one solution for providing hypermedia services to the users of a computing environment. This talk describes my research within the domain of open hypermedia systems and relates this work to the concept of pervasive hypermedia.

Pervasive hypermedia is the notion of providing hypermedia services at all levels of a computing environment from the depths of the operating system up through toolkits and services to applications and end-user scripting languages. My research has focused on producing techniques and building blocks for obtaining pervasive hypermedia. In particular, I will discuss techniques for improving an open hypermedia system's support of heterogeneity, integrating open hypermedia systems with the World Wide Web, and reducing the developmental effort associated with open hypermedia client integration. The latter technique involves a novel integration of an open hypermedia system with a user-interface toolkit providing a default level of hypermedia services to applications constructed with the toolkit.

The talk will frame these techniques within the relevant research context and position them with respect to related work. The talk concludes with a discussion of future research issues for pervasive hypermedia and opportunities for generalizing the techniques for use in other domains.
