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.
The field which studies ontologies so conceived is sometimes referred to as applied ontology. [1] Every academic discipline or field, in creating its terminology, thereby lays the groundwork for an ontology. Each uses ontological assumptions to frame explicit theories, research and applications.
Individuals (instances) are the basic, "ground level" components of an ontology. The individuals in an ontology may include concrete objects such as people, animals, tables, automobiles, molecules, and planets, as well as abstract individuals such as numbers and words (although there are differences of opinion as to whether numbers and words are classes or individuals).
Moreover, Heidegger went on to separate his fundamental ontology from previous ontologies. Heidegger wrote that clarifying the meaning of being is required for the basis of all fields of science. For Heidegger, the ontical forms of research conducted by scientists presuppose the fundamental-ontological. As he expresses it:
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 ...
The concept of ontology and what people mean by ontology is diverse; therefore, tracing the ontological turn in anthropology remains difficult. However, if ontology refers to the study of reality then ontological anthropology incorporates theoretical and methodological elements of anthropology to a study of being or existence. [3]
[2] [3] An explicit specification of a conceptualization is an ontology, and it may occur that a conceptualization can be realized by several distinct ontologies. [2] An ontological commitment in describing ontological comparisons is taken to refer to that subset of elements of an ontology shared with all the others.
Applied ontology is the application of Ontology for practical purposes. This can involve employing ontological methods or resources to specific domains, [ 1 ] such as management , relationships , biomedicine , information science or geography .
