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.
Lemma (from Ancient Greek λῆμμα premise, assumption, from Greek λαμβάνω I take, I get) may refer to: Language and linguistics
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 ...
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 linguistics, lexicalization is the process of adding words, ... First, the semantic form (which is specified for meaning) is converted into a lemma, ...
Surface forms of words are those found in natural language text. The corresponding lexical form of a surface form is the lemma followed by grammatical information (for example the part of speech, gender and number). In English give, gives, giving, gave and given are surface forms of the verb give. The lexical form would be "give", verb.
The lemma is defined as the structure within the mental lexicon that stores semantic and syntactic information about a word, such as part of speech and the meaning of the word. Research has shown that the lemma develops first when a word is acquired into a child's vocabulary, and then with repeated exposure the lexeme develops.
