In Yet Another Keyword Extractor (Yake), text features are exploited in an unsupervised manner. YAKE is a basic unsupervised automatic multi-lingual keyword extraction method that identifies the most relevant keywords in a text by using text statistical data from single texts. This technique does not rely on dictionaries, external corpora, text size, language, or domain, and it does not require training on a specific set of documents. The Yake algorithm’s major characteristics are as follows:
          i) Supports texts of different sizes, domains or languages.
          ii) Unsupervised approach.
          iii) Corpus-independent.
          iv) Domain and language independent.
          v) Single-document.
