This lexicon is an extended version of Sloleks 1.2 (http://hdl.handle.net/11356/1039). It contains all the original data from Sloleks with added information about the stress of each word form, which is included two ways: information about stress location only, and information about stress location and type. The stress assignment was performed automatically, with algorithms based on deep neural networks which correctly predicted accent location in around 90 % and combined accent type and location in about 87.5 % of test data. Therefore all accents are not correct.
