| Summary: | Suicide is a critical mental health issue and one of the leading causes of death worldwide. Several studies in suicidology claim that emotional dysregulation is a factor triggering suicidal behavior. In today’s digital age, individuals often express suicidal ideation on social media platforms to seek help, empathy, or advice. The primary objective of this study is to classify suicide notes based on their emotional content using machine and deep learning algorithms. We propose an innovative approach to automatically identify emotional changes in a suicide note’s content, leveraging these shifts as key indicators of suicidal ideation. The goal is to automatically identify the correlation between latent emotional states in suicide notes and their classification as either suicidal or non-suicidal. We employed a long short-term memory (LSTM) neural network to analyze emotional patterns and address various binary classification scenarios. Results demonstrated an F-measure exceeding 80% in all suicide note classification scenarios. Our analysis revealed that the vocabulary used in suicide notes collected from social media often differs from that found in notes written by individuals who have actually completed suicide. Additionally, we observed that suicide attempters typically do not directly express suicidal ideation but instead use non-death-related vocabulary, which presents a greater challenge in identifying genuine suicidal thoughts. |
