Prolexbase 2.0 and 2.2

Prolexbase 2.0 and 2.2 is a multilingual relational dictionary of proper names, conceived initially at the University of Tours, France and at the University of Belgrade, Serbia, and further developed 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. A large majority of the data have been extracted from Wikipedia and GeoNames. All data have been manually validated.

Prolexbase creation has been supported by the following projects:

  • Technolangue programme from the French Ministry of Industry (2003-2005),

  • Egide Pavle-Savic programme from the French Ministry of Foreign Affairs, the French Ministry of Research, and the Serbian Ministry of Science (2004-2005),

  • ERDF Nekst project (2009-2014),

  • European (CIP ICT-PSP) CESAR project, part of META-NET (2011-2013).

The construction and contents of Prolexbase have been described in:
