| | Ontology (computer science) - Wikipedia, the free encyclopedia |
 | | Different ontologies in the same domain can also arise due to different perceptions of the domain based on cultural background, education, ideology, or because a different representation language was chosen. | | | An important use of attributes is to describe the relationships (also known as relations) between objects in the ontology. | | | What are the differences between a vocabulary, a taxonomy, a thesaurus, an ontology, and a meta-model? |

| | ontology |
| | Ontology is a branch of metaphysics which is concerned with being, including theories of the nature and kinds of being. | | | Pluralistic ontologies hold that there is no unity to Being and that there are numerous kinds of being. | | | Monistic ontologies hold that there is only one being, such as Spinoza’s theory that God or Nature is the only substance. |

| | Virtual Travelog Judging the likely Success of an Ontology |
| | What you write in your second paragraph about reasons for failure of ontologies, are valid arguments to claim that representations that have these shortcomings, are not ontologies by definition. | | | And if you don't believe relational databases are ontologies you should read this. | | | General purpose ontologies capable of self definition have existed for a century at the most and have only had any practical application outside mathematics and philosophy since the widespread adoption of the computer in the 1960's and 70's. |

| | Tom Gruber says that "an ontology is a specification of a conceptualization." His definition is incomplete and vague. | | | The American Heritage Dictionary (4th ed.) provides the following definition: "The branch of metaphysics that deals with the nature of being." In short, ontology is the centuries-old branch of philosophy that has as its subject the unchanging features of the universe. | | | Ontology is not about peoples’ conceptions or interpretations, but about the world. |

| | Ontology - Wikipedia, the free encyclopedia |
| | During the Enlightenment the view of René Descartes that "cogito ergo sum" ("I think therefore I am") had generally prevailed, although Descartes himself did not believe the question worthy of any deep investigation. | | | According to this theory, then, ontology is the science of being inasmuch as it is being, or the study of beings insofar as they exist. | | | When one applies this process to nouns such as electrons, energy, contract, happiness, time, truth, causality, and god, ontology becomes fundamental to many branches of philosophy. |

| | What is an ontology and why we need it |
| | After all, the ontology is a reflection of the real world, and if no categorization exists in the real world, then the ontology should reflect that. | | | For example, we can use the Ontolingua ontology library (http://www.ksl.stanford.edu/software/ontolingua/) or the DAML ontology library (http://www.daml.org/ontologies/). | | | If the people who will maintain the ontology describe the domain in a language that is different from the language of the ontology users, we may need to provide the mapping between the languages. |

| | Ontology, introduction |
| | It is sometimes considered to be identical to metaphysics, but we prefer to use it in a more specific sense, as that part of metaphysics that specifies the most fundamental categories of existence, the elementary substances or structures out of which the world is made. | | | Ontology (the "science of being") is a word, like metaphysics, that is used in many different senses. | | | In a sense, only the things in his ontology can exist for that agent. |

| | Dictionary of Philosophy of Mind - ontology |
| | What we may call ontology is the attempt to say what entities exist. | | | For example, a philosopher might include in her ontology quarks, people, substances, and institutions, while her metaphysics might include such claims as: quarks are necessarily such that they obey thus and such physical laws; people are essential rational beings; substances are by nature indestructible; institutions are essentially conventional entities; and so on. | | | Metaphysics, by contrast, is the attempt to say, of those entities, what they are. |
