Study Notes

Ontology Properties

Ontologies deal with heterogeneity in space, requiring tools to handle conflicting definitions and interweaving local theories.
Ontologies evolve over time, necessitating protocols for their development and adaptation.

Importance of Ontology

Knowledge sharing problem: different systems use different concepts and terms, making it difficult to share knowledge between systems.
Ontologies facilitate knowledge sharing by describing the semantics of information sources and making content explicit.
Goals of ontology research include developing reusable ontologies and tools for building, merging, and translating between ontologies.

Benefits of Ontology

Explicit ontology supports shared understanding among agents, interoperability between tools, and systems engineering.
Ontology enables reusability, defines vocabulary and concepts, and plays a role similar to mathematics in physics (theory of content).
Ontology defines necessary and sufficient concepts and methods, forming a common knowledge theory.

Ontology as Artifact

Ontology is a constructed artifact, such as a glossary, taxonomy, dictionary, thesaurus, knowledge base, database schema, conceptual map, or template.

Conceptual Graph

Conceptual Graph (CG) is a knowledge representation system developed by John Sowa.
CG consists of concept nodes and relation nodes, representing entities, attributes, states, events, and their interconnections.

Ontology vs. Knowledge Base

Ontology provides the basic structure for a knowledge base, capturing the intrinsic conceptual structure of a domain.
Knowledge base represents what is true about a real or hypothetical world, using the concepts and terms defined in the ontology.

Ontological Analysis

Ontological analysis clarifies the structure of knowledge in a domain, forming the heart of any knowledge representation system.
Weak analyses lead to incoherent knowledge bases, and effective ontological analysis is crucial for devising an effective knowledge-representation system.

Ontology vs. Object-Oriented (OO)

Building an ontology appears similar to building an Object-Oriented software, but with key differences.
Ontologies reflect the structure of the world, whereas OO objects may not, and the modeler of the domains makes commitments about the existence of classes of entities.
