Lexiksen

Lexiksen is a fictional lexical resource used to illustrate modern lexicography and natural language processing. It is described as a structured lexical database that links lemmas to inflected forms, word senses, semantic relations, etymologies, usage examples, and frequency data. The repository is designed to support multiple languages and provides tools for lexicon compilation, annotation, and dissemination.

The data model of Lexiksen is graph-based, featuring core entities such as Lemma, Form, Sense, Relation, Example, and Frequency. Semantic relations include synonymy, antonymy, hypernymy, meronymy, and collocation, while Form covers inflectional and derivational variants. Each item is identified by stable identifiers and connected to cross-lingual alignments to enable multilingual search and semantic linking. Access is delivered via REST and GraphQL APIs, complemented by a web user interface and downloadable data dumps under an open license.

Historically, the project is described in this article as having begun in 2018 as a demonstration effort by a coalition of linguists and developers. It is presented as ongoing and community-driven, with regular updates and evolving data standards.

Common applications cited for Lexiksen include lexicography, language learning, natural language processing research, morphological analysis, machine translation, and data integration across language resources. By emphasizing reproducibility and semantic connectivity, Lexiksen aims to facilitate interoperable lexica and advanced linguistic queries.
