Slovenskočeský NLP workshop (SloNLP 2019) 5th International Workshop 19th Conference on Information Technologies – Applications and Theory Hotel Zornička, Donovaly, Slovakia, September 20–24, 2019. Preface SloNLP is a workshop focused on Natural Language Processing (NLP) and Computa- tional Linguistics. Its primary aim is to promote cooperation among NLP researchers in Slovakia and the Czech Republic. The topics of the workshop include automatic speech recognition, automatic natural language analysis and generation (morphology, syntax, semantics, etc.), dialogue systems, machine translation, information retrieval, practical applications of NLP technologies, and other topics of computational linguistics. To further encourage cooperation and sharing of information among NLP researchers in Slovakia and Czechia, we offer Open session, an opportunity for anyone to present his work, without writing a paper. As invited speakers, we welcome people that apply NLP in a private sector to contrast with mainly academic participants. This year, Lukáš Vrábel presents his experiences from Central Europe AI startup studio. This year, 5 papers are accepted for a poster presentation and there is one participant of the Open Session.
