The student is preparing data visualization tools for criminalists. Facilitates investigation

Experts from the Faculty of Informatics and the Institute of Computer Science assume that police officers put together a lot of resources and diverse information. They have a number of isolated tools that do not cooperate with each other.


Kristína Zákopčanová, Ph.D. student at the Faculty of Informatics of MU, comes into contact with the difficult police environment every day. Thanks to a project funded by the Ministry of the Interior and solved at the Institute of Computer Science of MU, it helps to invent a data visualization system for use in criminal investigations.

When you first hear about Kristina's work, you want to remember all sorts of crime serials. However, the young doctoral student hinders these ideas a bit.

“At first I didn't notice it at all, and later, when we talked to the police, I realized that we were really suggesting something to be used in the investigation. But don't imagine anything wild, they just tell us what they have to do, no details, and no secret information at all, ”laughs Kristina, who is particularly pleased about the fact that she is doing something that really makes people work easier. Moreover, in the vital sphere of life.

She did not think of something like this at a bachelor's degree. In her bachelor's thesis, she dealt with a topic that she later realized that she was not really interested, and then she was looking for something completely different that she would like to pursue in her spare time.

Previously, she was interested in the work of Barbora Kozlíková from the Department of Computer Graphics and Design, so she arranged a coffee consultation with her, which was the beginning of their cooperation. It was Kozlíková who involved Kristína in the project for the Ministry of the Interior, led by Tomáš Rebok.

Experts from the Faculty of Informatics and the Institute of Computer Science at MU assume that police officers collect a lot of resources and diverse information. They have a number of isolated tools that do not cooperate with each other, and some already have more modern and efficient options.

“Our goal is to map exactly what needs they have, in which we could help them, and to suggest the most effective solutions,” says Kristína, who is in charge of the visualization of the information obtained. “It can be individuals, events, field knowledge, or bank reports. All of this can be organized into one system and presented in a visual form so that one can suddenly see the context that he had not previously known. ”

Kristína has been working for police officers for some time, in June she submitted a diploma, which recapitulates her work. Of course, she has gone through a process that everyone has to go through to join two previously unconnected disciplines: One side wants to improve its work and wants the other side, but it doesn't know the possibilities. And the other party has no idea what the work of the first one looks like, and therefore what it is possible to offer. In this case, the informatics overcome this by a lot of common meetings, presenting ideas and constantly repainting them.

“Whenever we throw something in the trash, we come up with another important topic that we have to deal with,” says Kristína. It needs to be addressed how to compile data, who will have access to it, how to label information that is not yet 100%, or how the results are exported to other law enforcement authorities. However, the actual design of the result, which could be a program that all police officers have installed on a computer, will no longer be the task of faculty researchers. They will mainly give know-how how everything should look like.

Kristína herself admits that she used to work sometimes at times, that the ideal result could not be proposed immediately, but it must be done by gradual steps and discarding older, not entirely satisfactory variants. “But after a few years, I take it as a normal part of my work, part of discovery and that nothing is wrong. And if we throw away something, it means that we have shown a better way. ”
