LexiClean: An annotation tool for rapid multi-task lexical normalisation

NLP systems are often challenged by difficulties arising from noisy, non-standard, and domain specific corpora. The task of lexical normalisation aims to standardise such corpora, but currently lacks suitable tools to acquire high-quality annotated data to support deep learning based approaches. In this paper, we present LexiClean 1 , the first open-source web-based annotation tool for multi-task lexical normalisation.
