Proto-Indo-European Lexicon (PIE Lexicon) is the generative etymological dictionary of Indo-European languages. The reconstruction of Proto-Indo-European (PIE) is obtained by applying the comparative method, the output of which equals the Indo-European (IE) data. Due to this the Indo-European sound laws leading from PIE to IE, revised in Pyysalo 2013, can be coded using Finite-State Transducers (FST). For this purpose the foma finite-state compiler by Mans Hulden (2009) has been chosen in PIE Lexicon. At this point PIE Lexicon generates data of some 120 Indo-European languages with an accuracy rate of over 99% and is therefore the first dictionary in the world capable of generating (predicting) its data entries by means of digitized sound laws.
