Large-Scale Cognate Recovery
نویسندگان
چکیده
We present a system for the large scale induction of cognate groups. Our model explains the evolution of cognates as a sequence of mutations and innovations along a phylogeny. On the task of identifying cognates from over 21,000 words in 218 different languages from the Oceanic language family, our model achieves a cluster purity score over 91%, while maintaining pairwise recall over 62%.

متن کاملAspectual and focal functions of Cognate-Head-Dependent Constructions: Evidence from Africa
Cognate-Head-Dependent Constructions (CHDCs) are employed across numerous genera in Africa to signpost alternations in the aspectual characteristics of a predicate or the information focus of a clause. The co-occurrence of a finite lexical verb (the cognate head) and an etymologically related (deverbal) noun or non-finite verb form (the cognate dependent) in such structures is interpreted with ...
