lexical gap

A lexical gap happens when a word in one language is not lexicalized in another language (Lehrer 1970). (Freihat, Khalilia, Bella & Giunchiglia, 2024)
Lexical gaps arise when a lexicalized concept of a language has no correspondence to any lexicalized concept in the other language. (Branco, Grilo, Bolrinha, Saedi, Branco, Silva, Querido, de Carvalho, Gaudio, Avelãs & Pinto, 2020)

Among the possible type of discrepancies the so-called lexical gaps is a most significant one (Bentivogli and Pianta 2000; Bentivogli and Pianta 2000) : a lexical gap exists in a certain language when another language expresses a concept with a lexical unit whereas the language at stake can only express the same concept with a compositional combination of words. (Branco, Grilo, Bolrinha, Saedi, Branco, Silva, Querido, de Carvalho, Gaudio, Avelãs & Pinto, 2020)
Lexical gaps are caused by specificities of the two languages dictionary gaps are produced by limitations of any dictionary/thesaurus/wordnet size. (Rudnicka, Maziarz, Piasecki & Szpakowicz, 2012)
Lexical gaps are implemented in our resource at the synset level while phrasets are implemented on the word level. (Freihat, Khalilia, Bella & Giunchiglia, 2024)
The last type of lexical gaps is a mismatch resulting from different structuring of information as in the case of English and Polish family relation hierarchies. (Rudnicka, Maziarz, Piasecki & Szpakowicz, 2012)
The problem of lexical gaps is solved by allowing the storage of not only lexica but also free phrases. (Simov, 2013)
