In linguistics, a semantic field is a related set of words grouped semantically (by meaning) that refers to a specific subject. The term is also used in anthropology, computational semiotics, and technical exegesis.

Hypernymy and hyponymy are the semantic relations between a generic term (hypernym) and a more specific term (hyponym). The hypernym is also called a supertype, umbrella term, or blanket term. The hyponym names a subtype of the hypernym. The semantic field of the hyponym is included within that of the hypernym. For example, "pigeon", "crow", and "hen" are all hyponyms of "bird" and "animal"; "bird" and "animal" are both hypernyms of "pigeon", "crow", and "hen".
A semantic network, or frame network is a knowledge base that represents semantic relations between concepts in a network. This is often used as a form of knowledge representation. It is a directed or undirected graph consisting of vertices, which represent concepts, and edges, which represent semantic relations between concepts, mapping or connecting semantic fields. A semantic network may be instantiated as, for example, a graph database or a concept map. Typical standardized semantic networks are expressed as semantic triples.
Semantic networks are used in natural language processing applications such as semantic parsing and word-sense disambiguation. Semantic networks can also be used as a method to analyze large texts and identify the main themes and topics (e.g., of social media posts), to reveal biases (e.g., in news coverage), or even to map an entire research field.
In linguistics, the term semantic domain refers to an abstract space containing all the 'meanings' of every term in a language. Since multiple words can have the same meaning, the semantic domain can also be thought of as grouping the terms based on meaning. Harriet Ottenheimer (2006), a writer in Linguistic Anthropology, defines a semantic domain as a “specific area of cultural emphasis”.
In lexicography a semantic domain or semantic field is defined as "an area of meaning and the words used to talk about it ... For instance English has a domain ‘Rain’, which includes words such as rain, drizzle, downpour, raindrop, puddle.". Semantic domains are the foundational concept for initial stages of vernacular dictionary building projects. This uses techniques such as SIL International's Dictionary Development Process (DDP), RapidWords, or software such as FLEx, The Combine, or WeSay. These techniques rely on extensive lists of semantic domains that are relevant to vernacular languages.
