is there anywhere a source where I can find lemmatize for different languages? As I mention Manticore official offers only German,Russian, (Ukraine) and English.
we using AOT lemmatizer from http://www.aot.ru and added recently Ukrainian Lemmatizer https://github.com/manticoresoftware/lemmatizer-uk via Pymorphy2 module.
You could ask AOT team for help or try to find another python module that could be integrated
