- Analysing Emotions During Interrogations: A Case StudyPublication . Garcia, José António da Silva Pinto; Miragaia, Rolando Lúcio Germano; Grilo, Carlos Fernando de Almeida; Domingues, Patrício RodriguesIn a context of rapid technological advancement and increasing integration of Artificial Intelligence (AI) across various fields, this work explores the application of AI in the domain of criminal investigation, specifically within the context of interrogations. The research presents a dual and complementary nature: the development of a software application for the Portuguese Military Judiciary Police (PJM) and a scientific contribution in the field of multimodal emotion analysis. The first component focused on the design and implementation of the INTU-AI (Intuition Artificial Intelligence) program, a tool aimed at supporting Military Judicial Police (PJM, from Portuguese Polícia Judiciária Militar) investigators by digitizing and automating administrative procedures related to interrogations. INTU-AI integrates models for Facial Emotion Recognition (FER), Speech Emotion Recognition (SER), and Text-Based Emotion Analysis, functioning as a complete end-to-end solution. The second component represents a scientific contribution in the form of a proof-of-concept study for dynamic multimodal emotion analysis. Due to the lack of publicly available datasets of criminal interrogations, the MELD (Multimodal EmotionLines Dataset) was employed as the experimental basis, given its resemblance to real-life interaction contexts. This part of the work, structured according to the CRISP-DM methodology, explored three hypotheses regarding the relative importance of each modality in emotional evaluation.
