Prolexbase is a multilingual relational dictionary of proper names, conceived at the University of Tours, France and further developed at the University of Belgrade, Serbia, and at the Polish Academy of Sciences (IPIPAN). It contains a language-independent typology of proper names with 4 supertypes and 34 types, as well as various language-independent or language-specific relations (synonymy, meronymy accessibility, variation etc.). A pivot-oriented design of concepts yields alignment of proper names in a language with their counterparts if other languages. Currently, the resources counts about 40,000 Polish, 33,000 English and 100,000 French proper names together with their corresponding 165,000 Polish, 18,000 English and 142,393 English inflected forms. A large majority of the data have been extracted from Wikipedia and GeoNames. All data have been manually validated.
