This paper presents an open-source toolkit for negation detection.It identifies negation cues and their corresponding scope in either raw or parsed text using maximummargin classification.The system design draws on best practice from the existing literature on negation detection, aiming for a simple and portable system that still achieves competitive performance.Pretrained models and experimental results are provided for English.
