Määritelmiä / Definitions

Wikipedia: Ontology "...an ontology is a data model that represents a set of concepts within a domain and the relationships between those concepts. It is used to reason about the objects within that domain."
Tom Gruber: What is an Ontology? "An ontology is a specification of a conceptualization."
John F. Sowa: Ontology "The subject of ontology is the study of the categories of things that exist or may exist in some domain. The product of such a study, called an ontology, is a catalog of the types of things that are assumed to exist in a domain of interest D from the perspective of a person who uses a language L for the purpose of talking about D."
Ontology Works, Inc: What is Ontology? "'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."
Raul Corazzon: Ontology. A Resource Guide for Philosophers "Ontology is the theory of objects and their ties."

Kritiikkiä / Criticism

Clay Shirky: Ontology is Overrated: Categories, Links, and Tags "What I think is coming instead are much more organic ways of organizing information than our current categorization schemes allow, based on two units -- the link, which can point to anything, and the tag, which is a way of attaching labels to links. The strategy of tagging -- free-form labeling, without regard to categorical constraints -- seems like a recipe for disaster, but as the Web has shown us, you can extract a surprising amount of value from big messy data sets."

Historiaa / History

SHOE - Simple Ontology HTML Extensions "SHOE is a small extension to HTML which allows web page authors to annotate their web documents with machine-readable knowledge."
DAML - The DARPA Agent Markup Language "The goal of the DAML effort is to develop a language and tools to facilitate the concept of the Semantic Web."
OIL (Ontology Inference/Interchange Language) "...a proposal for a web-based representation and inference layer for ontologies, which combines the widely used modelling primitives from frame-based languages with the formal semantics and reasoning services provided by description logics."

Kielellisiä semanttisia verkkoja / Linguistic Semantic Webs

Wikipedia: Ontology language "...ontology languages are formal languages used to construct ontologies."
Wikipedia: F-logic F-logic (frame logic) is a knowledge representation- and ontology language. It accounts in a declarative fashion for structural aspects of object-oriented and frame-based languages. Features include, among others, object identity, complex objects, inheritance, polymorphism, query methods, encapsulation. F-logic stands in the same relationship to object-oriented programming as classical predicate calculus stands to relational database programming.

Deskriptiologiikka / Description Logics

Wikipedia: Description logic "Description logics (DL) are a family of knowledge representation languages which can be used to represent the terminological knowledge of an application domain in a structured and formally well-understood way."

SWRL – Semantic Web Rule Language

A Proposal for a SWRL Extension "This is a description of a proposed extension of SWRL to function-free handle unary/binary first-order logic. This is intended to be a minimal extension that fits well with SWRL, OWL, and RDF."
SWRL: A Semantic Web Rule Language Combining OWL and RuleML, version 0.6 "This document contains a proposal for a Semantic Web Rule Language (SWRL) based on a combination of the OWL DL and OWL Lite sublanguages of the OWL Web Ontology Language with the Unary/Binary Datalog RuleML sublanguages of the Rule Markup Language."

Ontology Alignment / Ontology Matching

Wikipedia: Ontology alignment "Ontology Alignment, or ontology matching, is the process of determining correspondences between concepts. A set of correspondences is also called an alignment."
The Ontology Alignment Source "Ontology alignment is the automated resolution of semantic correspondences between the representational elements of heterogenous sytems. ... The Ontology Alignment Source supports the ontology alignment research community by providing a forum that promotes the sharing and comparison of research data."
OntologyMatching.org "This web site provides a repository of information devoted to different aspects of ontology matching."

Ontology Acquisition

OntoWeb SIG5 list "A typical approach in ontology learning from text first involves the extraction of (more or less complex) terms from a domain-specific corpus. Extracted terms are statistically processed to determine their relevance for the domain corpus at hand and clustered into groups with the purpose of identifying a taxonomy of potential classes. Additionally, relations can be identified, mostly by computing a statistical measure of connectedness between identified clusters."
