A contrast set is a bounded collection of items, each of which could fill the same slot in a given schema, syntactic structure, or other linguistic environment. The seven days of the week, the fifty United States, the eight Hawaiian islands, the letters in the alphabet, the categories "male" and "female," the students in a class, or the flavors on offer at an ice cream store are all examples of contrast sets.
Contrast sets may be relatively natural in origin (such as the eight Hawaiian islands) or relatively conventional (such as the fifty United States). The mastery of certain conventional contrast sets is essential to basic socialization: for example, calendrical units, musical notes, and elements of writing systems like numerals and the alphabet. These contrast sets frequently become the subject of synesthesias or ideasthesias.
Semantic relations that form or represent contrast sets include cohyponymy (for example, major categories of trees include pine, elm, willow, maple, and so on) and comeronymy (for example, major components of a motor vehicle include an engine or motor, a transmission, one or more batteries, a set of wheels and tires, and so on).
Linguistic anthropologists Harold Conklin and Charles Frake were the first to work out the concept of the contrast set in the 1950s, and the concept was described in detail in Frake's article "The ethnographic study of cognitive systems." [1]
Knowledge representation and reasoning aims to allow information technology to recognize and make use of the meaning and interrelationships of contrast sets. For example, ontology components for ontologies, as well as graph databases, are tools to help with that goal.
A concept is defined as an abstract idea. It is understood to be a fundamental building block underlying principles, thoughts and beliefs. Concepts play an important role in all aspects of cognition. As such, concepts are studied within such disciplines as linguistics, psychology, and philosophy, and these disciplines are interested in the logical and psychological structure of concepts, and how they are put together to form thoughts and sentences. The study of concepts has served as an important flagship of an emerging interdisciplinary approach, cognitive science.
Language is a structured system of communication that consists of grammar and vocabulary. It is the primary means by which humans convey meaning, both in spoken and written forms, and may also be conveyed through sign languages. The vast majority of human languages have developed writing systems that allow for the recording and preservation of the sounds or signs of language. Human language is characterized by its cultural and historical diversity, with significant variations observed between cultures and across time. Human languages possess the properties of productivity and displacement, which enable the creation of an infinite number of sentences, and the ability to refer to objects, events, and ideas that are not immediately present in the discourse. The use of human language relies on social convention and is acquired through learning.
In metaphysics, ontology is the philosophical study of being. It investigates what types of entities exist, how they are grouped into categories, and how they are related to one another on the most fundamental level. Ontologists often try to determine what the categories or highest kinds are and how they form a system of categories that encompasses the classification of all entities. Commonly proposed categories include substances, properties, relations, states of affairs, and events. These categories are characterized by fundamental ontological concepts, including particularity and universality, abstractness and concreteness, or possibility and necessity. Of special interest is the concept of ontological dependence, which determines whether the entities of a category exist on the most fundamental level. Disagreements within ontology are often about whether entities belonging to a certain category exist and, if so, how they are related to other entities.
In phonology and linguistics, a phoneme is a set of phones that can distinguish one word from another in a particular language.
The idea of linguistic relativity, also known as the Sapir–Whorf hypothesis, the Whorf hypothesis, or Whorfianism, is a principle suggesting that the structure of a language influences its speakers' worldview or cognition, and thus individuals' languages determine or shape their perceptions of the world.
Semantics is the study of reference, meaning, or truth. The term can be used to refer to subfields of several distinct disciplines, including philosophy, linguistics and computer science.
In cognitive linguistics, conceptual metaphor, or cognitive metaphor, refers to the understanding of one idea, or conceptual domain, in terms of another. An example of this is the understanding of quantity in terms of directionality or the understanding of time in terms of money.
Ethnolinguistics is an area of anthropological linguistics that studies the relationship between a language and the nonlinguistic cultural behavior of the people who speak that language.
A linguistic universal is a pattern that occurs systematically across natural languages, potentially true for all of them. For example, All languages have nouns and verbs, or If a language is spoken, it has consonants and vowels. Research in this area of linguistics is closely tied to the study of linguistic typology, and intends to reveal generalizations across languages, likely tied to cognition, perception, or other abilities of the mind. The field originates from discussions influenced by Noam Chomsky's proposal of a Universal Grammar, but was largely pioneered by the linguist Joseph Greenberg, who derived a set of forty-five basic universals, mostly dealing with syntax, from a study of some thirty languages.
Linguistic determinism is the concept that language and its structures limit and determine human knowledge or thought, as well as thought processes such as categorization, memory, and perception. The term implies that people's native languages will affect their thought process and therefore people will have different thought processes based on their mother tongues.
Cognitive semantics is part of the cognitive linguistics movement. Semantics is the study of linguistic meaning. Cognitive semantics holds that language is part of a more general human cognitive ability, and can therefore only describe the world as people conceive of it. It is implicit that different linguistic communities conceive of simple things and processes in the world differently, not necessarily some difference between a person's conceptual world and the real world.
In linguistics, linguistic competence is the system of unconscious knowledge that one knows when they know a language. It is distinguished from linguistic performance, which includes all other factors that allow one to use one's language in practice.
In information science, an upper ontology is an ontology that consists of very general terms that are common across all domains. An important function of an upper ontology is to support broad semantic interoperability among a large number of domain-specific ontologies by providing a common starting point for the formulation of definitions. Terms in the domain ontology are ranked under the terms in the upper ontology, e.g., the upper ontology classes are superclasses or supersets of all the classes in the domain ontologies.
A diaphoneme is an abstract phonological unit that identifies a correspondence between related sounds of two or more varieties of a language or language cluster. For example, some English varieties contrast the vowel of late with that of wait or eight. Other English varieties contrast the vowel of late or wait with that of eight. This non-overlapping pair of phonemes from two different varieties can be reconciled by positing three different diaphonemes: A first diaphoneme for words like late, a second diaphoneme for words like wait, and a third diaphoneme for words like eight.
Eskayan is an artificial auxiliary language of the Eskaya people of Bohol, an island province of the Philippines. It is grammatically Boholano, the native language of Bohol, with a substituted lexicon. While Eskayan has no mother-tongue speakers, it is taught by volunteers in at least three cultural schools in the southeast interior of the province.

A writing system is a method of visually representing verbal communication, based on a script and a set of rules regulating its use.
In philosophy, a process ontology refers to a universal model of the structure of the world as an ordered wholeness. Such ontologies are fundamental ontologies, in contrast to the so-called applied ontologies. Fundamental ontologies do not claim to be accessible to any empirical proof in itself but to be a structural design pattern, out of which empirical phenomena can be explained and put together consistently. Throughout Western history, the dominating fundamental ontology is the so-called substance theory. However, fundamental process ontologies have become more important in recent times, because the progress in the discovery of the foundations of physics has spurred the development of a basic concept able to integrate such boundary notions as "energy," "object", and those of the physical dimensions of space and time.
The Integrational theory of language is the general theory of language that has been developed within the general linguistic approach of integrational linguistics.
The Usage-based linguistics is a linguistics approach within a broader functional/cognitive framework, that emerged since the late 1980s, and that assumes a profound relation between linguistic structure and usage. It challenges the dominant focus, in 20th century linguistics, on considering language as an isolated system removed from its use in human interaction and human cognition. Rather, usage-based models posit that linguistic information is expressed via context-sensitive mental processing and mental representations, which have the cognitive ability to succinctly account for the complexity of actual language use at all levels. Broadly speaking, a usage-based model of language accounts for language acquisition and processing, synchronic and diachronic patterns, and both low-level and high-level structure in language, by looking at actual language use.
