  This study explores language's fragmenting effect on user-generated content
by examining the diversity of knowledge representations across 25 different
Wikipedia language editions. This diversity is measured at two levels: the
concepts that are included in each edition and the ways in which these concepts
are described. We demonstrate that the diversity present is greater than has
been presumed in the literature and has a significant influence on applications
that use Wikipedia as a source of world knowledge. We close by explicating how
knowledge diversity can be beneficially leveraged to create "culturally-aware
applications" and "hyperlingual applications".
