lexiaal

Lexiaal is a term used in linguistics and language technology to denote the lexical dimension of language, focusing on words and their representations in mental and computational lexica. It refers to the collection of lexical entries that encode form, meaning, and usage for a language's vocabularies.

Definition and scope: Lexiaal concerns the central repository of a language's lexemes, including lemmas, inflected forms, parts of speech, morphological information, semantic senses, collocations, and subcategorization frames. It is commonly contrasted with grammatical or syntactic structures, which organize how words combine rather than what words themselves are.

Origin and usage: The term is described in some linguistic discussions as a blend of the concept of a lexicon with an adjectival suffix, highlighting its focus on lexical rather than purely syntactic aspects. In practice, lexiaal resources encompass dictionaries, wordnets, and lexical databases that underpin natural language processing and linguistic research.

Examples: In a lexiaal entry for the verb "run," the senses might include “to move swiftly on foot” and “to operate (a machine or system).” Morphological variants such as "runs" and "running" would be linked to the same lemma, with notes on tense, aspect, or voice as appropriate.

Applications: Lexiaal analysis informs lexicography, language learning tools, speech recognition, machine translation, and other NLP tasks where accurate lexical information improves word sense disambiguation, morphological processing, and semantic mapping.
