Introduction of Viewpoints in Conceptual Graph Formalism
نویسندگان
چکیده
To represent knowledge in a context of several experts, it is interesting to model the multiple perspectives that different experts may have on the objects handled in their reasoning. The concept of a particular perspective called viewpoint, is already used in the field of object oriented representation or in the field of databases conception. Taking inspiration of research made in object oriented representation, we propose in this paper an extension of the conceptual graph formalism to integrate viewpoints in the support and in the building oLconceptual graphs. We also study mechanisms for managing viewpoints.

Using Viewpoints and CG for the Representation and Management of a Corporate Memory in Concurrent Engineering
In Concurrent Engineering, several participants (designers, managers,...) stemming from different specialities, collaborate in order to build a system. In this paper, we propose a representation with the Conceptual Graph formalism to keep a trace of the design process in Concurrent Engineering as a project memory. Such design process is a cycle of individual design and collaborative evaluation....
متن کاملComparison of Conceptual Graphs for Modelling Knowledge of Multiple Experts
When modeling expertise from multiple experts, expertise conflicts among the expertise models of the different experts must be tackled, so as to build their common expertise model. The domain level of an expertise model can be represented using Sowa’s conceptual graph formalism. This paper presents a method for conflict management during knowledge modeling from multiple experts: this method is ...
متن کاملExtending Conceptual Graphs for Representing Partial Knowledge
Conceptual Graphs (CGs) are a visual, logic based knowledge representation (KR) formalism. In this paper we show how Conceptual Graph Assemblies (CGAs), a combinatorial extension to Conceptual Graphs, can represent multiple perspectives on the same information and enable the creation and use of modular and reusable CG representations. The natural way of introduction disjunction in the logical s...
متن کاملThe Unit Graphs Framework: A graph-based Knowledge Representation Formalism designed for the Meaning-Text Theory
In this paper we are interested in the choice of a graph-based knowledge representation formalism that would allow for the representation, manipulation, query, and reasoning over linguistic knowledge of the Explanatory Combinatorial Dictionary of the Meaning-Text Theory (MTT). We show that neither the semantic web formalisms nor the Conceptual Graphs Formalism are suitable for this task, and we...
متن کاملA Conceptual Graph Approach to Support Multiperspective Development Environments
This paper demonstrates an application of Conceptual Graphs (CGs) in the area of software engineering. We employ CGs as a meta-representation language to enhance consistency checking within a multiperspective development environment, i.e. one which employs and utilises a number of ViewPoints. We have built a ViewPoint-based prototype called the √iewer+CG to show such application of CGs. A ViewP...
