Cover Picture: In this paper, we propose a feature extraction approach based on word embedding models. The proposed approach extracts semantic features characterized by contextual information that is hidden in the raw data representation. Our experiments conducted on three datasets showed that our feature extraction approach based on word embedding models has the potential to increase the classification performance of conventional machine learning algorithms that are applied to intrusion detection, and it is competitive with known feature extraction baselines in the state-of-the-art. This study shows that word embedding models can be used to carry out intrusion detection tasks accurately. Feature extraction based on word embedding models requires a higher computational time than simpler techniques, but leads to a higher accuracy, which is important for the identification of complex attacks.
