What are the general theories of semantics

Semantics explained in simple terms: definition and function

According to Wikipedia, the term semantics is defined as follows:

semantics (from Greek σημαίνεινsēmaínein 'Denote', 'belonging to the sign'), also Theory of meaning, is called the theory or science of the meaning of signs. character can in this case be words, phrases or symbols. Semantics is typically concerned with the relationships between signs and their meanings.

A distinction is made between the following main forms of semantics:

  • Semantics of sign systems (semiotics)
  • Semiasisology and Onomasiology
  • Semantics of languages ​​(linguistics)

With regard to semantic search engine optimization or semantic search as well as online marketing in general, we are primarily in the field of linguistics.

Semantics play an increasingly important role in the categorization, interpretation and delivery of information on the Internet. Many large online platforms such as Facebook and Google already use semantic functionalities.

How the semantics work

Semantics in the sense of linguistics is primarily about identifying the meaning of language. References that take place in certain environments (ontologies) are established via entities. This can be used to identify the context and meaning of entities. This allows entities to be categorized, but also evaluated.


Ontologies and Entities


Entities can be clearly identified using a unique ID and a combination of certain properties. In this way, terms with multiple meanings such as "Jaguar" (Jaguar can mean an animal, tank, car ...) can be clearly identified in terms of meaning. Entities can be people, companies, factual and abstract things, buildings ...


In semantics, ontologies represent an environment in which entities can be related to one another. A certain industry can serve as an ontology in which different market participants / companies function as an entity and are related to one another.
