Dear Reader, it is our pleasure to present to you Communication Papers of the 2019 Federated Conference on Computer Science and Information Systems (FedCSIS), which took place in Leipzig, Germany, on September 1-4, 2019.

The communication papers were introduced in 2017 as a separate category of contributions. They report on research topics worthy of immediate communication. They may be used to mark a hot new research territory or to describe work in progress in order to quickly present it to scientific community. They may also contain additional information omitted from the earlier papers or may present software tools and products in a research state.

FedCSIS 2019 was technically co-sponsored by: IEEE Region 8, IEEE Poland Section, IEEE Computer Society Technical Committee on Intelligent Informatics, IEEE Czechoslovakia Section Computer Society Chapter, IEEE Poland Section Gdańsk Computer Society Chapter, IEEE Poland Section Systems, Man, and Cybernetics Society Chapter, IEEE Poland Section Control System Society Chapter, IEEE Poland Section Computational Intelligence Society Chapter, Committee of Computer Science of the Polish Academy of Sciences, Polish Operational and Systems Research Society, Mazovia Cluster ICT Poland and Eastern Cluster ICT Poland. FedCSIS 2019 was sponsored by Intel.

During FedCSIS 2019, keynote lectures were delivered by:

• Enrique Alba, University of Málaga, Spain, “Intelligent Systems for Smart Cities”
• Francisco Herrera, Dept. Computer Sciences and Artificial Intelligence Andalusian Research Institute in Data Science and Computational Intelligence (DaSCI) University of Granada, “Deep Data and Big Learning: More quality data for better knowledge”
• George Spanoudakis, Research Centre for Adaptive Computing Systems (CeNACS), School of Mathematics, Computer Science and Engineering, City, University of London, “Cyber security risks: Comprehensive mitigation through technical, contractual and financial mitigation mechanisms”

FedCSIS 2019 consisted of five Tracks and a Doctoral Symposium. Tracks were divided into Technical Sessions. Sessions were preannounced in Call for Papers as track-related events (conferences, symposia, workshops, special sessions).

• DS-RAIT'19 - 6th Doctoral Symposium on Recent Advances in Information Technology

The 2019 edition of an AAIA’19 Data Mining Challenge is called Clash Royale Challenge: How to Select Training Decks for Win-rate. This year the task is related to the problem of selecting an optimal training data subset for learning how to predict win-rates of the most popular Clash Royale decks. Awards for the winners of the contest were sponsored by: Esensei and the Mazovia Chapter of the Polish Information Processing Society. Papers resulting from the competition are included in the Conference Proceedings (Chapter of Track 1: AAIA).

Each paper, found in this volume, was refereed by at least two referees.

The program of FedCSIS required a dedicated effort of many people. Each event constituting FedCSIS had its own Organizing and Program Committee. We would like to express our warmest gratitude to all Committee members for their hard work in attracting and later refereeing 298 regular submissions.

We thank the authors of papers for their great contribution to research and practice in computing and information systems. We thank the invited speakers for sharing their knowledge and wisdom with the participants. Finally, we thank all those responsible for staging the conference in Leipzig. Organizing a conference of this scope and level could only be achieved by the collaborative effort of a highly capable team taking charge of such matters as conference registration system, finances, the venue, social events, catering, handling all sorts of individual requests from the authors, preparing the conference rooms, etc.

We hope you had an inspiring conference and an unforgettable stay in the beautiful city of Lepzig. We also hope to meet you again for FedCSIS 2020 in Sofia, Bulgaria.
