The knowledge representation language used, both for input and output, is based on first order logic with some extensions to handle quantitative and procedural knowledge. This paper reports on the ongoing effort in building an rdf ontology for the defacto standard conceptual model for library catalogs. Query processing is treated as a graph matching process. Knowledge can be symbolically represented in many ways, and the authors have chosen labeled graphs for their modeling and computational qualities. Pdf logical, graph based knowledge representation with cogui. The gkr system is based on the use of conceptual graphs as a knowledge representation scheme. Pdf logical, graph based knowledge representation with. Because graphs are a powerful and flexible knowledge representation we will. Graphbased knowledge representation model and pattern. In graphbased approach to knowledge representation graphs are considered for knowledge modeling and for computation.
This book studies a graphbased knowledge representation and reasoning formalism stemming from conceptual graphs, with a substantial focus on the computational properties. Pdf graphbased knowledge representation for gis data. This paper presents a proposal to create a graph representation for gis, using both spatial and nonspatial data and also including spatial relations between spatial objects. Knowledge acquisition with a pure graphbased knowledge representation model. A benefit of this approach is that labeled graphs, schemas and drawings provide an intuitive vehicle for knowledge representation. We motivate our work by a concrete real world application and demonstrate how using the cogui conceptual graphs. There is a wide range of applications of graphbased methods such as such. We motivate our work by a concrete real world application and demonstrate how using the cogui conceptual. Graph based knowledge representation and reasoning. In this paper, a new graph based modular knowledge storage and representation form is presented which is able to handle inaccurate and ambiguous information, to store, retrieve, modify, and extend.
