Concept mapping has a history of use in many disciplines as a formal or semi-formal diagramming technique. Concept maps have an abstract structure as typed hypergraphs, and computer support for concept mapping can associate visual attributes with node types to provide an attractive and consistent appearance. Computer support can also provide interactive interfaces allowing arbitrary actions to be associated with nodes such as hypermedia links to other maps and documents. This article describes a general concept mapping system that is open architecture for integration with other systems, scriptable to support arbitrary interactions and computations, and cutomizable to emulate many styles of map. The system supports collaborative development of concept maps across local area and wide area networks, and integrates with World-Wide Web in both client helper and server gateway roles. A number of applications are illustrated ranging through education, artificial intelligence, active documents...

Knowledge acquisition research supports the generation of knowledge-based systems through the development of principles, techniques, methodologies and tools. What differentiates knowledgebased system development from conventional system development is the emphasis on in-depth understanding and formalization of the relations between the conceptual structures underlying expert performance and the computational structures capable of emulating that performance. Personal construct psychology is a theory of individual and group psychological and social processes that has been used extensively in knowledge acquisition research to model the cognitive processes of human experts. The psychology takes a constructivist position appropriate to the modeling of human knowledge processes but develops this through the characterization of human conceptual structures in axiomatic terms that translate directly to computational form. In particular, there is a close correspondence between the intensional lo...

Widespread access to the Internet has led to the formation of geographically dispersed scientific communities collaborating through the network. The tools supporting such collaboration currently are based primarily on electronic mail through mailing list servers, and access to archives of research reports through ftp, gopher and world wide web. However, electronic communication can support the knowledge processes of scientific communities more directly through overtly represented knowledge structures. This paper describes some experiments in the use of knowledge acquisition (KA) and representation (KR) tools to define and analyze major policy and technical issues in an international research community responsible for one of the test cases in the Intelligent Manufacturing Systems (IMS) research program. It is concluded that distributed knowledge support systems in routine use by world-class scientific communities collaborating through the Internet will provide a major impetus to artific...

The Semantic Web relies heavily on the formal ontologies that structure underlying data for the purpose of comprehensive and transportable machine understanding. Therefore, the success of the Semantic Web depends strongly on the proliferation of ontologies, which requires fast and easy engineering of ontologies and avoidance of a knowledge acquisition bottleneck.

We present work in progress on a new methodology for leveraging the semantic content of ontologies to guide knowledge discovery in databases. Our system scans new databases to obtain type and constraint information, which users verify. Our system then uses this information in the context of a shared ontology to intelligently guide the potentially combinatorial process of feature construction. Further, our system learns each time it is applied, easing the user’s verification task on subsequent runs.

Abstract: An open architecture multimedia document publication system is described which integrates a number of different representation technologies to provide a medium offering a wide spectrum of usage, from emulation of current paper publication, through electronic document delivery, multimedia inclusion of video and sound, structured hypermedia linkage, and formal knowledge representation supporting simulation and inference. The research is targeted on exploring new forms of scholarly communication, and the publication system supports collaborative document development, the authentication of disseminated material, and the citation, annotation and reuse of such material. The document publication system provides a rich word processing and page makeup environment with all the facilities normally expected, and adds multimedia, hypermedia and computational facilities incrementally and naturally, with careful attention to the usability of the human-computer interface. The result is an interactive document in which knowledge is represented in a variety of ways, some targeted on human interaction, some targeted on computational analysis, simulation and inference, and such that the document can be printed as a conventional paper or book losing the dynamic aspects of the material but retaining the visual representation.

An overview of knowledge engineering research, practice, theories, methodologies, and tools is presented, and parallels are drawn with analogous phenomena and activities in requirements engineering. Knowledgebased systems are distinguished from other advanced information systems by their reflective emphasis on meta-information processing about the basis of system operation. In terms of requirements elicitation this corresponds to an emphasis on maintaining an audit trail from requirements through design, implementation, use and maintenance, that supports continuing user involvement in system specification, design and evolution. Examples of knowledge elicitation methodologies and tools are given, and it is suggested that they all have some applicability in requirements elicitation for advanced information system development. It is concluded that closer collaboration between the knowledge engineering and requirements engineering communities will be mutually beneficial. 1

Symbolic models represented in operational form provide a powerful information technology for computer-based reasoning, for example, in incorporating an organization's business rules in the operation of its information systems. Visual languages enable these models to be represented in semantic networks that are comprehensible to people and can be incorporated in documents such as the organization's procedures manual. This article describes stand-alone and web technology for active documents incorporating knowledge bases represented by editable semantic networks supporting inference.

The MATILDA multimedia authoring system has been developed to address issues related to authoring process and information management and representation. This paper presents our initial application of the structured graph visual formalism to the MATILDA data models. This has resulted in the introduction of a new group of automatically derivable links in the data models, and highlights some data model distinctions which we believe should be captured. We also discuss the possible use of the scalable editing and browsing operations that are part of the formalism. 1.
