• Abstract: This paper presents TransCrimeNet, a novel transformer-based model for predicting future crimes in criminal networks from textual data. Criminal network analysis has become vital for law enforcement agencies to prevent crimes. However, existing graph-based methods fail to effectively incorporate crucial textual data like social media posts and interrogation transcripts that provide valuable insights into planned criminal activities. To address this limitation, we develop TransCrimeNet which leverages the representation learning capabilities of transformer models like BERT to extract features from unstructured text data. These text-derived features are fused with graph embeddings of the criminal network for accurate prediction of future crimes. Extensive experiments on real-world criminal network datasets demonstrate that TransCrimeNet outperforms previous state-of-the-art models by 12.7\% in F1 score for crime prediction. The results showcase the benefits of combining textual and graph-based features for actionable insights to disrupt criminal enterprises.

• Framework for developing quantitative agent based models based on qualitative expert knowledge: an organised crime use-case [0.0]
  In order to model criminal networks for law enforcement purposes, a limited supply of data needs to be translated into validated agent-based models. What is missing in current criminological modelling is a systematic and transparent framework for modelers and domain experts. We propose FREIDA ( Framework for Expert-Informed Data-driven Agent-based models) for this purpose.

  We propose Spatial-Temporal Sequential Hypergraph Network (ST-SHN) to collectively encode complex crime spatial-temporal patterns. In particular, to handle spatial-temporal dynamics under the long-range and global context, we design a graph-structured message passing architecture. We conduct extensive experiments on two real-world datasets, showing that our proposed ST-SHN framework can significantly improve the prediction performance.

Our results suggest that differential crime reporting rates can lead to a displacement of predicted hotspots from high crime but low reporting areas to high or medium crime and high reporting areas.
