Yet Another Keyword Extractor (YAKE!)

YAKE! is a light-weight unsupervised automatic keyword extraction method which rests on text statistical features extracted from single documents to select the most important keywords of a text. The system does not need to be trained on a particular set of documents, neither it depends on dictionaries, external-corpus, size of the text, language or domain. It outperforms state-of-the-art methods under a number of collections of different sizes, languages or domains.
