Recent approaches to cognate detection.

A plus “+” indicates that the algorithm meets the requirement, a minus “-” indicates that its failure. ML (multilingual) refers to the ability of an algorithm to identify cognate words across more than two languages at the same time. RQ (requirements) refers to additional requirements apart from the raw word list data, such as needing reference phylogenies or extensive training data. FA (free availability) means that the method has a useable public implementation.
