What is Ontology

Handbook of Research on ICTs for Human-Centered Healthcare and Social Care Services
High-level knowledge and data representation structure. Ontologies provide a formal frame to represent the knowledge related with a complex domain, as a qualitative model of the system. Ontologies can be used to represent the structure of a domain by means of defining concepts and properties that relate them.

Abstract
Information and communication technologies have already become an inseparable part of healthcare sector activities. In the chapter, the authors discuss the issues of standardization and interoperability that are crucial for correct interconnection of medical and other devices and information systems. Their previous work in the area has led to the conclusion that successful integration of partial solutions is strongly dependent on the issue of interoperability of medical devices and information systems. It comprises problems of standardization of data acquisition, communication, processing, and storage, and the connected problem: correct data mapping between different ICT applications. They present several examples of partial solutions of communication and data format definition in dedicated areas.

Supply Chain Information System for Sustainability and Interoperability of Business Service
Information sharing among supply chain business partners using information systems is an important enabler for supply chain management. There are diverse types of data to be shared across supply chain, namely – order, inventory, shipment , and customer service . Consequently, information about these issues needs to be shared in order to achieve efficiency and effectiveness in supply chain management. In this way, information-sharing activities require that human and / or machine agents agree on common and explicit business-related concepts (the shared conceptualization among hardware / software agents customers, and service providers) are known as explicit ontologies; and this help to exchange data and derived knowledge out of the data to achieve collaborative goals of business operations.

Knowledge Engineering Methodology with Examples
(a) In computer science and information science, an ontology formally represents knowledge as a set of concepts within a domain, and the relationships between pairs of concepts. It can be used to model a domain and support reasoning about concepts. (b) In philosophy, ontology is the study of the nature of being, becoming, existence , or reality , as well as the basic categories of being and their relations. Traditionally listed as a part of the major branch of philosophy known as metaphysics, ontology deals with questions concerning what entities exist or can be said to exist, and how such entities can be grouped, related within a hierarchy, and subdivided according to similarities and differences.

Literature now generally agrees on the Gruber’s terms to define an ontology: explicit specification of a shared conceptualization of a domain. The domain is the world that the ontology describes. It can be a general domain or a more specific one. This description uses a vocabulary of concepts which is understandable and agreed by people of the domain; here is the meaning of “shared conceptualization”. The ontology can be implemented in several languages with a different level of formalization and expressivity, with no ambiguity that’s why ontology is an “explicit specification”.

The Role of Science, Technology, and the Individual on the Way of Software Systems Since 1968
In computer science, ontology is a formal representation of the knowledge by a set of concepts within a domain and the relationships between those concepts. The domain is the type of objects, and/or concepts that exist and their properties and relations. The creation of domain ontologies is the fundamental of the definition of any enterprise framework. Every information system has its own ontology. Software agents can communicate with each other via messages that contain expressions formulated in terms of an ontology. It is important to use an ontology for the connection with the user interface component. The user browses the ontology to better understand the vocabulary and to formulate queries at the desired level. Application programs containing a lot of domain knowledge may not explicitly store information in the database for various reasons. In this case, it is possible to constitute a knowledge base by an ontology.

Drawing, Information, and Design: Tools and Perspective for Conservation
A formal representation of entities described by their definitions and the relationships between their physical or conceptual contexts. There are two kinds of ‘property’ describing the latter: ‘data properties’, where the contents relate to other entities, and ‘object properties’, where the information refers directly to the entity being considered. The semantic framework may be expanded by other properties that express ‘rules’. These rules clarify the relationships between entities, and allow deductions to be inferred from the system, thus revealing potentially incoherent representations.

Classification of Semantic Web Technologies
The word ontology comes from the Greek ontos (being) and logia (written or spoken discourse). It is in use since Empedocles described the four elements – air, earth, fire, and water. In artificial intelligence, ontology is defined as a working model of concepts and interactions from a particular domain of knowledge, like medicine, mathematics, automobile repair, and so forth, which is used to easily describe the meaning of different contents that can be exchanged in information systems. Any ontology can be easily extended, refined, and reused by other ontologies, providing expressive representation for a wide diversity of real-world concepts.

The formal representation of knowledge as a set of concepts within a domain and the relationships among those concepts (Malafsky & Newman, n.d.; Ontology, n.d.). Within the field of computational intelligence, it is used as input to reason or make inferences about the entities within that domain, as well as to describe the domain. Sub-concepts include syntax (the way words are put together to form a sentence), semantics (the meaning of al symbol or concept within a specific context), pragmatics (the implications of that information in context) and context (the set of circumstances or details that are relevant to a specific incident or event).

An ontology is a formal, explicit specification of a shared conceptualization. Conceptualization refers to an abstract model of some phenomenon in the world by having identified the relevant concepts of that phenomenon. Explicit means that the type of concepts used, and the constraints on their use are explicitly defined. Formal refers to the fact that the ontology should be machine-readable. Shared reflects the notion that an ontology captures consensual knowledge, that is, it is not private of some individual, but accepted by a group.

How Semantic Web Technologies can Support the Mediation between Supply and Demand in the ICT Market: The Case of Customer Relationship Management
In computer science, an ontology is an explicit and formal representation of concepts, properties and relationships concerning a given domain, which specifies the semantics of a shared vocabulary. Actually, there is a huge variability in the formalization degree and in the specificity level of ontologies. Along the former dimension, ontologies range from rather informal controlled vocabularies to strongly axiomatized logic theories. As regards specificity, they range from rather general cross-domain foundational ontologies to semantic representations relevant to very specific application domains. Ontologies expressed in formal languages support, to some extent, automatic reasoning.

An Ontological Approach to Online Instructional Design
The term ontology essentially refers to the study of being or existence. It seeks to describe or posit the basic categories and relationships of being or existence to define entities and types of entities within its frame work. In Greek philosophy, ontology means understanding the eternal reality (Reginald, 1985). Plato defined the reality as primary and the perception and experience of reality as secondary. Socrates held the similar view that the purpose of learning was to recognize eternal truth and therefore the instruction was to remind someone of something already known and accepted as true (Spector, 2001). This classical view of ontology has changed due to a realization that the explication and uncovering of external reality involve human perceiver and that human judgment with respect to such uncovering is subject to error. One of the assumptions of modern ontology is that instruction should focus on bodies of knowledge rather than individual knowledge. Instead of relying on one-to-one correspondence between individual beliefs and external reality, the modern ontology proposes a coherence theory of truth in which acceptance or rejection of new beliefs should be based on how well new beliefs fit with and how coherent they are with the established beliefs (Quine & Ullian, 1978; Spector, 2001). This assumption is important in that it influences the formation of ontology in computer science in which the shared conceptualization of reality across knowledge domains is emphasized.

Context Modelling Approaches for Mobile Systems
An ontology is an explicit specification of a conceptualization. The term is borrowed from philosophy, where ontology is a systematic account of Existence. For knowledge-based systems, what “exists” is exactly that which can be represented. When the knowledge of a domain is represented in a declarative formalism, the set of objects that can be represented is called the universe of discourse. This set of objects, and the describable relationships among them, are reflected in the representational vocabulary with which a knowledge-based program represents knowledge. Thus, we can describe the ontology of a program by defining a set of representational terms. 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 are meant to denote, and formal axioms that constrain the interpretation and well-formed use of these terms

Ontology refers to the set of characteristics that specifies a certain class of individuals.

It is likely that the evolution of emotions and their expression from Mammals to Primates to Humans laid the basic foundations of that kind of shared ontology.

It can be a general domain or a more specific one. This description uses a vocabulary of concepts which is understandable and agreed by people of the domain; here is the meaning of “shared conceptualization.” The ontology can be implemented in several languages with a different level of formalization and expressivity, with no ambiguity that’s why ontology is an “explicit specification.”

SDRule Markup Language: Towards Modeling and Interchanging Ontological Commitments for Semantic Decision Making
There exist many definitions of ontology, amongst which the definition given by Tom Gruber is a widely accepted one. An ontology is “an explicit specification of a conceptualization …When the knowledge of a domain is represented in a declarative formalism, the set of objects that can be represented is called the universe of discourse. Those sets of objects, and the describable relationship among them, are reflected in the representational vocabulary with which a knowledge-base program represents knowledge…” (Gruber, 1993).

Clinical and Biomolecular Ontologies for E-Health
A semantic structure useful to standardize and provide rigorous definitions of the terminology used in a domain and to describe the knowledge of the domain. It is composed of a controlled vocabulary, which describes the concepts of the considered domain, and a semantic network, which describes the relations among such concepts. Each concept is connected to other concepts of the domain through semantic relations that specify the knowledge of the domain. A general concept can be described by several terms that can be synonyms or characteristic of different domains in which the concept exists. For this reason the ontologies tend to have a hierarchical structure, with generic concepts/terms at the higher levels of the hierarchy and specific concepts/terms at the lover levels, connected by different types of relations.
