CoBL: A New Breed of Databases on Cognacy in
Basic Lexicon

CoBL is a new database structure for exploring how languages within a family relate to each other in Cognacy in Basic Lexicon. Tailored for qualitative as well as quantitative research purposes, CoBL provides data-exploration websites to search the rich linguistic data covered: cognate sets, orthography, morphology, phonemic and IPA phonetic transcriptions, and links to further sources.

CoBL is a model extendable to any language family, but applied first to Indo-European as CoBL-IE, to succeed the IELex database by Michael Dunn (as used by Bouckaert et al. 2012, Chang et al. 2015). Data are compiled through the CoBL data-entry website, by a consortium of branch experts across Indo-European, working together with cross-family cognacy specialists to assign cognate sets and sub-sets. All contributors work to a new and very explicit set of lexeme selection guidelines, and an improved reference list of 200 precisely (re)defined comparison meanings.

Please note that this database is not publicly available yet. It is still under construction, and access is only provided to the research team members.
