Abstract:
The world harbors a diversity of some 6,500 mutually unintelligible languages.As has been increasingly observed by linguists, many minority languages are be-coming endangered and will be lost forever if not documented. Urgently indeed,many efforts are being launched to document and describe languages. This under-taking naturally has the priority toward the most endangered and least describedlanguages. For the first time, we combine world-wide databases on language de-scription (Glottolog) and language endangerment (ElCat, Ethnologue, UNESCO)and provide two online interfaces, GlottoScope and GlottoVis, to visualize thesetogether. The interfaces are capable of browsing, filtering, zooming, basic statis-tics, and different ways of combining the two measures on a world map back-ground. GlottoVis provides advanced techniques for combining cluttered dotson a map. With the tools and databases described we seek to increase the overallknowledge of the actual state language endangerment and description worldwide
