In information science, an ontology encompasses a representation, formal naming, and definitions of the categories, properties, and relations between the concepts, data, or entities that pertain to one, many, or all domains of discourse.

2024年6月25日 · This article will explore what ontologies are, how they are used, and why they are important for improving data management and communication in areas like artificial intelligence, semantic web, and knowledge management.

Ontology is the philosophical study of being. It is traditionally understood as the subdiscipline of metaphysics focused on the most general features of reality. As one of the most fundamental concepts, being encompasses all of reality and every entity within it.

Problem-solving methods, domain-independent applications, and software agents use ontologies and knowledge bases built from ontologies as data. For example, in this paper we develop an ontology of wine and food and appropriate combinations of wine with meals.

ontology, the philosophical study of being in general, or of what applies neutrally to everything that is real. It was called “first philosophy” by Aristotle in Book IV of his Metaphysics.

What is an Ontology? A formal, explicit specification of a shared conceptualization. Ontology vs KB? Why not amortize the effort and share ontologies? Semantic Web <...>? Is the taxonomic relationship (instance-of, subclass) primary? Are definitions of, or constraints on, terms provided? Is the definitional language as rich as a full logic?

2021年10月29日 · In a recent lunch-and-learn with the Ethyca team, we defined an ontology simply as: A set of concepts within a domain and the relationships that hold between them in order to represent that system.

2022年5月17日 · Ontologies can be used in different ways depending on the nature of the problem at hand. For example, ontologies can be applied to improve information retrieval systems by providing a common understanding of concepts that humans and computers can both use.

2016年5月19日 · We define an ontology as a representational artifact, and explore the implications of this. We outline our preferred realist view of universals, and contrast it with alternative views (nominalism and conceptualism).
