Conceptual Modeling Using Conceptual Graphs
The next generation of task support systems aims at providing the relevant knowledge to knowledge-dependent activities, reducing the effort required to find or infer this knowledge from the data. In order to exploit knowledge associated with (or embedded in) databases and to migrate from data to knowledge management environments, conceptual modeling languages must offer more expressiveness than...
متن کاملConceptual Graphs
A conceptual graph (CG) is a graph representation for logic based on the semantic networks of artificial intelligence and the existential graphs of Charles Sanders Peirce. Several versions of CGs have been designed and implemented over the past thirty years. The simplest are the typeless core CGs, which correspond to Peirce’s original existential graphs. More common are the extended CGs, which ...
متن کاملConceptual Graphs Are Also Graphs
The main objective of this paper is to add one more brick in building the CG model as a knowledge representation model autonomous from logic. The CG model is not only a graphical representation of logic, it is much more: it is a declarative model encoding knowledge in a mathematical theory, namely labelled graph theory, which has eecient computable forms, with a fundamental graph operation on t...
متن کاملInferring Conceptual Relationships When Ranking Patients
Searching patients based on the relevance of their medical records is challenging because of the inherent implicit knowledge within the patients’ medical records and queries. Such knowledge is known to the medical practitioners but may be hidden from a search system. For example, when searching for the patients with a heart disease, medical practitioners commonly know that patients who are taki...
متن کاملInferring Conceptual Structure from Cross-Language Data
Semantic categories vary across languages, but this variation is constrained: many logically possible semantic categories are not attested, and similar categories often appear in unrelated languages. This pattern suggests a universal conceptual basis to the variation, such that different languages provide different snapshots of the same conceptual terrain. A semantic map is a means of capturing...
