Garg, Pankaj K. (1987): Abstraction Mechanisms in Hypertext. In: Weiss, Stephen and Schwartz, Mayer (eds.) Proceedings of ACM Hypertext 87 Conference November 13-15, 1987, Chapel Hill, North Carolina. pp. 375-395.

Abstraction is the means by which information can be stored and retrieved from an information structure at different levels of detail and from different perspectives. As such, abstraction mechanisms in hypertext are interesting to study and evaluate. In this paper we study the abstraction mechanisms in hypertext from a theoretical perspective. Abstractions then become various first-order logic formulae. Specifically we consider abstraction: sets, sequences, aggregations generalizations, revisions, and information structures. Interesting results of this work are the definition of level of generality of a hypertext node, the demonstration of revision histories as a partial order, and the notion of compatible-similar nodes. Also defined in this paper is the notion of primitive hypertexts versus application hypertexts, and the usage of attributes of nodes (illustrated by the use of keywords) across various abstractions. An illustration of the concepts is given using the contexts mechanism suggested by Delisle and Schwartz [DS87].

Garg, Pankaj K. and Scacchi, Walt (1987): On Designing Intelligent Hypertext Systems for Information Management in Software Engineering. In: Weiss, Stephen and Schwartz, Mayer (eds.) Proceedings of ACM Hypertext 87 Conference November 13-15, 1987, Chapel Hill, North Carolina. pp. 409-432.

Information management in large scale software engineering is a challenging problem. Hypertext systems are best suited for this purpose because of the diversity in information types that is permitted in the nodes of a hypertext. The integration of a hypertext system with software engineering tools results in a software hypertext system. We describe the design of such a system called DIF. Based on our experiences in using DIF, we recognized the need and the potential for developing a hypertext system that could utilize knowledge about its users and their software tasks and products. Such a system might then be able to act as an active participant in the software process, rather than being just a passive, albeit useful storage facility. As such, we define an Intelligent Software Hypertext System (I-SHYS) as a software hypertext system which is knowledgeable about its environment and can use such knowledge to assist in the software process. This knowledge is partly embedded in the design of an I-SHYS (in terms of the `agents' that I-SHYS supports) and partly defined during the use of I-SHYS (in terms of tasks that agents perform). We present a framework for defining and organizing this knowledge, describe potential uses of such knowledge, identify limits of our approach, and suggest methods for circumventing them.
