On The Road To Intelligent Web Applications, Hisham Assal, Kym J. Pohl, Jens G. Pohl

Collaborative Agent Design (CAD) Research Center

Increasing access to data sources on the Internet offers expanding opportunities for equipping intelligent applications with the content they require whether broad in scope or rich in detail. Although typically originating within the web in a semi-structured form, with the use of inference-based translation and analysis mechanisms such content can be transformed into useful information and ultimately into actionable knowledge. Service-Oriented Architecture (SOA) offers a platform for accessing the web as invocable resources and effectively incorporating multiple sources of data and capabilities on the Internet into enterprise applications. Adding inference capabilities to SOA-based applications not only aids in the translation …

Increasing The Expressiveness Of Owl Through Procedural Attachments, Dennis Taylor, Jens G. Pohl

Collaborative Agent Design (CAD) Research Center

The purpose of this paper is to provide an introduction to the OWL Web ontology language, a survey focused on the current state of the art in OWL inferencing capabilities, and a historical perspective on procedural attachments. The perspective is aligned with current OWL research. Several limitations of the OWL language and proposed extensions to overcome these limitations are discussed. A framework that provides empirical testing support for evaluating the effects of procedural attachments to the OWL inferencing capabilities is outlined. The examples presented suggest that it is possible to provide rule-based extensibility support for OWL that does not limit …

The Representation Of Context In Computer Software, Hisham Assal, Kym Pohl, Jens G. Pohl

Collaborative Agent Design (CAD) Research Center

Computers do not have the equivalent of a human cognitive system and therefore store data simply as the numbers and words that are entered into the computer. For a computer to interpret data it requires an information structure that provides at least some level of context. This can be accomplished utilizing an ontology of objects with characteristics, semantic behavior, and a rich set of relationships to create a virtual version of real world situations and provide the context within which intelligent logic (e.g., agents) can automatically operate.

This paper discusses the process of developing ontologies that serve to …
