Detection of Criminal Texts for the Polish State Border Guard
share
This paper describes research on the detection of Polish criminal texts appearing on the Internet. We carried out experiments to find the best available setup for the efficient classification of unbalanced and noisy data. The best performance was achieved when our model was fine-tuned on a pre-trained Polish-based transformer language model. For the detection task, a large corpus of annotated Internet snippets was collected as training data. We share this dataset and create a new task for the detection of criminal texts using the Gonito platform as the benchmark.
