  Online forums provide a unique opportunity for online users to share comments
and exchange information on a particular topic. Understanding user behaviour is
valuable to organizations and has applications for social and security
strategies, for instance, identifying user opinions within a community or
predicting future behaviour. Discovering the semantic aspects in Incel forums
are the main goal of this research; we apply Natural language processing
techniques based on topic modeling to latent topic discovery and opinion mining
of users from a popular online Incel discussion forum. To prepare the input
data for our study, we extracted the comments from Incels.co. The research
experiments show that Artificial Intelligence (AI) based on NLP models can be
effective for semantic and emotion knowledge discovery and retrieval of useful
information from the Incel community. For example, we discovered
semantic-related words that describe issues within a large volume of Incel
comments, which is difficult with manual methods.
