Abstract

Detecting criminal activity online is not a new concept but how it can occur is changing. Technology and the data generated by the influx of new devices has a vital part to play in this changing landscape. For example, using social media information such as content, location data, and activity
are examples of information that can be used to detect criminal activity and, in some studies, can even be used to forecast and predict future occurrences. This paper explores the application of deep learning for the detection of embedded toxic text content in images shared on social media platforms. In this work, we propose a machine learning solution for the detection of toxic images based on embedded text content. The project utilizes GloVe word embeddings for data augmentation for improved prediction capabilities. Our methodology details the implementation of Long Short-term memory Gated recurrent unit models and their Bidirectional variants, comparing our approach to related works, and highlighting evident improvements. The best performing model, Bidirectional LSTM, achieved 0.92 testing accuracy and 0.88 inference accuracy with 0.92 and 0.88 F1-score accordingly.
