The Linguasphere Observatory (Observatoire Linguistique) is a language research network. It was created in
France in
1983 and is currently based in
Wales. They have devised an innovative scheme of
philological classification, which includes a hierarchy of relationships based partly on percentages of
lexical similarity between language's core vocabularies, and also an unusual system that zigzags between genetic and geographic categories (which they call phylozones and geozones, respectively; see
Linguasphere language code for more details). They also promote multilingualism.
