What is the Concept of Ontology in the Semantic Web
An ontology can show the qualities of a subject area and how they are related by defining a set of ideas and categories that reflect the subject. Ontologies use a system of categories to represent entities, thoughts, and events, along with all of their interconnected attributes and relationships.
Why the Need for Ontology
Ontologies are created in every academic area or field to reduce complexity and arrange facts into information and knowledge. Explicit theories, research, and applications are all framed by ontological assumptions. New ontologies could help with problem resolution in that area. Translating research papers in any subject is an issue that is made easier when professionals from different countries retain a common jargon vocabulary in their own languages.
In data mining, ontology is a working model of entities and interactions that can be described generically or in the context of a specific field of knowledge or practice, such as healthcare or academics. An ontology can take numerous forms, but it will always include a vocabulary of terms as well as some explanation of their meaning. This includes definitions and an explanation of how concepts are linked, which combined create a framework for the domain and limit the vocabulary that can be used. The goal is to provide a common vocabulary and conceptual framework for data sharing in that field. Ontologies are significant in the way the new age semantic search tools like 3RDi Search work.
Ontology and the Semantic Web
Ontologies, which serve as unambiguous conceptual knowledge models that make domain information accessible to data systems, have become a hot issue thanks to text mining. They are critical to the vision of the Semantic Web and the working of semantic search tools, because they provide the semantics language that is used to tag websites in a form that machines can understand. Ontologies, as studied in the context of information analysis, are inspired by disciplines such as AI's symbolic representation of knowledge, software engineering's formal logic and machine learning, and software engineering's conceptual modelling, while also incorporating Web-enabled functionalities.
Ontology and LOD Mapping
In the text mining world and the world of semantic search tools, LOD stands for Linked Open Data, and LOD mapping is strongly related with ontology. LOD is structured data in a machine-readable format that isn't always appealing to the eye. Applied ontologies have evolved from a knowledge-intensive conceptual model for closed system applications to a lightweight representation tool for an open and decentralized environment over time. New options for sharing, reusing, and utilizing LOD mapping with existing ontologies also provide new development obstacles. The Semantic Web's essential components are LOD mapping and ontologies.
Elements of Ontology
Now that we have understood the meaning and significance of Ontology, let us have a quick look at the elements that are the building blocks of ontology. You need to understand this if you want to understand how the new age semantic search tools work.
1] Concept
A concept is a term that represents a set or class of entities within a domain.
Concepts are of the following 2 types as mentioned below.
- Primitive concepts
- Defined Concepts
2] Relations
Relations is a term that is used to denote the interactions between concepts themselves or their properties. Relations can be of the following 2 types:
- Taxonomy
- Associative Relationships
3] Instances
Instances are referred to as the real-world examples represented by a concept. A knowledge base is a term used to refer to associated instances, when combined with an ontology.
4] Axioms
An axiom is a term used to refer to a set of rules that are used to restrict values for instances or classes. It can also include more generalized rules.
Today, we have powerful new age semantic search tools like 3RDi Search that use the concept of ontology and semantics for advanced text mining and analysis.
