Semantic technologies are playing an increasingly popular role as a means for advancing the capabilities of knowledge management systems. Among these advancements, researchers have successfully leveraged semantic technologies, and their accompanying techniques, to improve the representation and search capabilities of knowledge management systems. This paper introduces a further application of semantic techniques. We explore semantic relatedness as a means of facilitating the development of more “intelligent” engineering knowledge management systems. Using semantic relatedness quantifications to analyze and rank concept pairs, this novel approach exploits semantic relationships to help identify key engineering relationships, similar to those leveraged in change management systems ...


A Semantic Information Model For Capturing And Communicating Design Decisions, Justin A. Rockwell, Ian R. Grosse, Sundar Krishnamurty, Jack C. Wileden Sep 2010

A semantic information model to improve reuse and communication of engineering design knowledge is presented in this paper. We consider design to be a process involving a sequence of decisions informed by the current state of information. As such, the information model developed is structured to reflect the conceptualizations of engineering design decisions with a particular emphasis on semantically capturing design rationale. Through the approach presented, knowledge reuse is achieved by communicating design rationale. A case study is presented to illustrate two key features of the approach: (1) seamless integration of separate modular domain ontologies and instance knowledge related to ...


Improved Knowledge Management Through First-Order Logic In Engineering Design Ontologies, Paul Witherell, Sundar Krishnamurty, Ian R. Grosse, Jack C. Wileden May 2010

Improved Knowledge Management Through First-Order Logic In Engineering Design Ontologies, Paul Witherell, Sundar Krishnamurty, Ian R. Grosse, Jack C. Wileden

This paper presents the use of first-order logic to improve upon currently employed engineering design knowledge management techniques. Specifically, this work uses description logic in unison with Horn logic, to not only guide the knowledge acquisition process but also to offer much needed support in decision making during the engineering design process in a distributed environment. The knowledge management methods introduced are highlighted by the ability to identify modeling knowledge inconsistencies through the recognition of model characteristic limitations, such as those imposed by model idealizations. The adopted implementation languages include the Semantic Web Rule Language, which enables Horn-like rules to ...


Intellectual Property Protection In Collaborative Design Through Lean Information Modeling And Sharing, Yan Wang, Pamela N. Ajoku, José C. Brustoloni, Bart O. Nnaji Jun 2006

Intellectual Property Protection In Collaborative Design Through Lean Information Modeling And Sharing, Yan Wang, Pamela N. Ajoku, José C. Brustoloni, Bart O. Nnaji

Establishing efficient, effective, and trustworthy engineering collaboration while protecting intellectual property is vital to maintain organizational competence in today’s global business environment. In this paper, a lean information modeling and sharing framework is described to support engineering data security management in a peer-to-peer collaborative environment. It allows for selective and interoperable data sharing with fine-grained access control at both the server and client sides, thus securing different levels of design information dissemination for intellectual property protection purposes. The considerations of time and value-adding activity with roles, policy delegation relation in a distributed context, and fine-grained control at data set ...
