  Ontology (computer science) - Wikinfo
In computer science, an ontology is the attempt to formulate an exhaustive and rigorous conceptual schema within a given domain, a typically hierarchical data structure containing all the relevant entities and their relationships and rules (theorems, regulations) within that domain.
The purpose of a computational ontology is not to specify what does or does not 'exist', but to create a database, which is a human artifact, containing concepts referring to entities of interest to the ontologist, and which will be useful in performing certain types of computations.
Computer programs can use an ontology for a variety of purposes including inductive reasoning, classification, a variety of problem solving techniques, as well as to facilitate communication and sharing of information between different systems.

In computer science, an ontology is the attempt to formulate an exhaustive and rigorous conceptual schema within a given domain, a typically hierarchical data structure containing all the relevant entities and their relationships and rules (theorems, regulations) within that domain.
The computer science usage of the term ontology is derived from the much older usage of the term in philosophy, where it means the study of being or existence as well as the basic categories thereof.

The computer science usage of the term ontology is derived from the much older usage of the term ontology in philosophy.
A computer science example is that, by default, all computer programs have a foundation ontology consisting of a processor instruction set, standard library in a programming language, files in accessible file systems, or some other list of 'what exists'.

 What is an Ontology?   (Site not responding. Last check: 2007-10-16)
In such an ontology, definitions associate the names of entities in the universe of discourse (e.g., classes, relations, functions, or other objects) with human-readable text describing what the names mean, and formal axioms that constrain the interpretation and well-formed use of these terms.
In short, a commitment to a common ontology is a guarantee of consistency, but not completeness, with respect to queries and assertions using the vocabulary defined in the ontology.
Ontologies are also not limited to conservative definitions, that is, definitions in the traditional logic sense that only introduce terminology and do not add any knowledge about the world (Enderton, 1972).

For the term in computer science, see ontology (computer science).'' ---- In philosophy, ontology (from the Greek ων = being and λόγος = word/speech) is the most fundamental branch of metaphysics.
Aristotle described ontology as "the science of being qua being".
According to this theory, then, ontology is the science of being with regard to the aspect of being, or the study of beings insofar as they exist.

 Foundation ontology   (Site not responding. Last check: 2007-10-16)
In computer science jargon, a foundation ontology or upper ontology is a hierarchy of entities and associated rules (both theorems and regulations) that attempts to describe those general entities that do not belong to a specific problem domain.
In philosophy of mathematics, a foundation ontology is an ontology in the formal philosophical sense that is deemed to play a role in the foundations of mathematics.
Hilary Putnam made the distinction in 1975, arguing that one could believe in a realist philosophy of mathematical foundations without also accepting Plato's ontology or his sacred geometry, thus the labels "Platonist" and "realist" were not to be held equivalent.

 What is an ontology
Ontology is a field of Philosophy concerned with the "nature of existence." It's practice dates unequivocally to Aristotle, however the name is roughly three centuries old.
In Computer Science, "an ontology" is usually defined as "a specification of a conceptualization." One might easily ask what that means, and I will describe it in more detail, however I should point out that the growing popularity of the term has of course diluted its original intent.
While philosophers have been talking about this for hundreds of years, computer systems have made the problem more pressing, since they encode a conceptualization of one person or group, and typically are very brittle with respect to making it clear what conceptualization has been encoded, and tolerating other conceptualizations.

 Conference : FOIS-2006 — OntoWiki   (Site not responding. Last check: 2007-10-16)
When we design a computer to take stock of a ship yard or check that all goes well at the veterinary hospital, we need to ensure that our system operates in a consistent and reliable way even when manipulating information that involves subtle issues of semantics and identity.
The tools of formal ontology address precisely these needs, but a real effort is required in order to apply such philosophical tools to the domain of information systems.
The purpose of FOIS is to provide a forum for genuine interdisciplinary exchange in the spirit of a unified effort towards solving the problems of ontology, with an eye to both theoretical issues and concrete applications.
