The semantic gap characterizes the difference between two descriptions of an object by different linguistic representations, for instance languages or symbols. According to Andreas M. Hein, the semantic gap can be defined as "the difference in meaning between constructs formed within different representation systems". [ 1 ]
A morphological gap is the absence of a word that could exist given the morphological rules of a language, including its affixes. [1] For example, in English a deverbal noun can be formed by adding either the suffix -al or -(t)ion to certain verbs (typically words from Latin through Anglo-Norman French or Old French).
Lexicology is the branch of linguistics that analyzes the lexicon of a specific language.A word is the smallest meaningful unit of a language that can stand on its own, and is made up of small components called morphemes and even smaller elements known as phonemes, or distinguishing sounds.
Conceptual semantics is a framework for semantic analysis developed mainly by Ray Jackendoff in 1976. Its aim is to provide a characterization of the conceptual elements by which a person understands words and sentences, and thus to provide an explanatory semantic representation (title of a Jackendoff 1976 paper).
A semantic field denotes a segment of reality symbolized by a set of related words. The words in a semantic field share a common semantic property. [6] A general and intuitive description is that words in a semantic field are not necessarily synonymous, but are all used to talk about the same general phenomenon. [7]
In linguistics, semantic analysis is the process of relating syntactic structures, from the levels of words, phrases, clauses, sentences and paragraphs to the level of the writing as a whole, to their language-independent meanings. It also involves removing features specific to particular linguistic and cultural contexts, to the extent that ...
Legal and Healthcare Informatics: Semantic parsing can extract and structure important information from legal documents and medical records to support research and decision-making. Semantic parsing aims to improve various applications' efficiency and efficacy by bridging the gap between human language and machine processing in each of these ...
Semantic similarity is a metric defined over a set of documents or terms, where the idea of distance between items is based on the likeness of their meaning or semantic content [citation needed] as opposed to lexicographical similarity.
