Criminal behavior has always attracted the interest of people. The European project called Visual Analytics for Sense-Making in Criminal Intelligence Analysis (Visual Analytics for understanding and analysis in the operational-search activity), or simply VALCRI has set a goal to thoroughly understand the crimes with the help of artificial intelligence and processing huge amount of data. This project was sponsored by the European Commission. Its essence lies in the processing of anonymous reports on crimes, other data, searching for non-obvious connections between them and providing results in graphical form, allowing users to easily draw conclusions. The authors say that the findings of an independent program to do is not, but will serve as a powerful tool for investigators and law enforcement officers.
