Speculative ontology aims to determine which entities actually exist, for example, whether there are numbers or whether time is an illusion. [81] Martin Heidegger proposed fundamental ontology to study the meaning of being. Metaontology studies the underlying concepts, assumptions, and methods of ontology.
Each domain ontology typically models domain-specific definitions of terms. For example, the word card has many different meanings. An ontology about the domain of poker would model the "playing card" meaning of the word, while an ontology about the domain of computer hardware would model the "punched card" and "video card" meanings.
For example, in the ontology that contains the concept Ford Explorer and the concept Ford Bronco might be related by a relation of type is defined as a successor of . The full expression of that fact then becomes: Ford Explorer is defined as a successor of : Ford Bronco; This tells us that the Explorer is the model that replaced the Bronco.
Example of a constructed MBED Top Level Ontology based on the nominal set of views. [1]In computer science, information science and systems engineering, ontology engineering is a field which studies the methods and methodologies for building ontologies, which encompasses a representation, formal naming and definition of the categories, properties and relations between the concepts, data and ...
In Being and Time, Martin Heidegger reframes Edmund Husserl's phenomenological project into what he terms fundamental ontology.This is based on an observation and analysis of Dasein ("being-there"), human being, investigating the fundamental structure of the Lebenswelt (lifeworld, Husserl's term) underlying all so-called regional ontologies of the special sciences.
Traditional ontology asks "Why is there anything?", whereas Heidegger's fundamental ontology asks, "What does it mean for something to be?," writes Taylor Carman (2003). ). Carman elaborates: Heidegger's fundamental ontology is relevant to traditional ontology in that it concerns "what any understanding of entities necessarily presupposes, namely, our understanding of that in virtue of which ...
Willard Van Orman Quine provided an early and influential formulation of ontological commitment: [4]. If one affirms a statement using a name or other singular term, or an initial phrase of 'existential quantification', like 'There are some so-and-sos', then one must either (1) admit that one is committed to the existence of things answering to the singular term or satisfying the descriptions ...
Ontology learning (ontology extraction,ontology augmentation generation, ontology generation, or ontology acquisition) is the automatic or semi-automatic creation of ontologies, including extracting the corresponding domain's terms and the relationships between the concepts that these terms represent from a corpus of natural language text, and encoding them with an ontology language for easy ...
