Query processing is treated as a graph matching process. Knowledge acquisition with a pure graphbased knowledge representation model. Pdf graphbased knowledge representation for gis data. The gkr system is based on the use of conceptual graphs as a knowledge representation scheme. We motivate our work by a concrete real world application and demonstrate how using the cogui conceptual. 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. Graph based knowledge representation and reasoning.
This book studies a graphbased knowledge representation and reasoning formalism stemming from conceptual graphs, with a substantial focus on the computational properties. This paper reports on the ongoing effort in building an rdf ontology for the defacto standard conceptual model for library catalogs. Graphbased knowledge representation model and pattern. We motivate our work by a concrete real world application and demonstrate how using the cogui conceptual graphs. In graphbased approach to knowledge representation graphs are considered for knowledge modeling and for computation. Because graphs are a powerful and flexible knowledge representation we will. Pdf logical, graph based knowledge representation with. Pdf logical, graph based knowledge representation with cogui. Knowledge can be symbolically represented in many ways, and the authors have chosen labeled graphs for their modeling and computational qualities. 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. A benefit of this approach is that labeled graphs, schemas and drawings provide an intuitive vehicle for knowledge representation.
