In morphology and lexicography, a lemma (pl.: lemmas or lemmata) is the canonical form, [1] dictionary form, or citation form of a set of word forms. [2] In English, for example, break, breaks, broke, broken and breaking are forms of the same lexeme, with break as the lemma by which they are indexed.
A lexeme (/ ˈ l ɛ k s iː m / ⓘ) is a unit of lexical meaning that underlies a set of words that are related through inflection.It is a basic abstract unit of meaning, [1] a unit of morphological analysis in linguistics that roughly corresponds to a set of forms taken by a single root word.
In this step, meaning and the syntactic elements of a lexical item are realized as the lemma. Lemma retrieval, as explained through a spreading-activation theory, is part of a network of separate elements consisting of the abstract concept, the lemma and the lexeme. Lemma retrieval is aided by the activation level of the concept that has yet to ...
In computational linguistics, lemmatization is the algorithmic process of determining the lemma of a word based on its intended meaning. Unlike stemming , lemmatization depends on correctly identifying the intended part of speech and meaning of a word in a sentence, as well as within the larger context surrounding that sentence, such as ...
Lemma (from Ancient Greek λῆμμα premise, assumption, from Greek λαμβάνω I take, I get) may refer to: Language and linguistics
The word lexicon derives from Greek word λεξικόν (lexikon), neuter of λεξικός (lexikos) meaning 'of or for words'. [1] Linguistic theories generally regard human languages as consisting of two parts: a lexicon, essentially a catalogue of a language's words (its wordstock); and a grammar, a system of rules which allow for the ...
In linguistics, a word stem is a part of a word responsible for its lexical meaning. Typically, a stem remains unmodified during inflection with few exceptions due to apophony (for example in Polish, miast-o ("city") and w mieść-e ("in the city"); in English, sing, sang, and sung, where it can be modified according to morphological rules or peculiarities, such as sandhi).
In the fields of computational linguistics and applied linguistics, a morphological dictionary is a linguistic resource that contains correspondences between surface form and lexical forms of words. Surface forms of words are those found in natural language text.
