Jan Hajič specializes in computer software and statistics in linguistics. He is working with a whole range of leading Czech and world linguists and programmers on the Czech morphological frequency dictionary. This book is the product of a long-time collective project focused on the computational morphology of Czech language. The stochastic disambiguation procedure outlined in this study represents the first systematic treatment of languages of the inflective type, to which most Slavic languages, as well as Latin, Old Greek and ancient Indo-European languages belong. Therefore, the present monograph may be of broader interest, being useful not only for the processing of Czech, but also for comparative research and for handling the corresponding phenomena in other languages.
