Fast and unsupervised methods for multilingual cognate clustering
Table 5: The results of training the PMI and PHMM systems on the ASJP 40 word lists and the full word lists of Indo-European, Mayan, and Austronesian.
['Family', 'Training word pairs', 'Online PHMM  [ITALIC] m', 'Online PHMM  [ITALIC] α', 'Online PHMM F-score', 'Online PMI  [ITALIC] m', 'Online PMI  [ITALIC] α', 'Online PMI F-score', 'Batch PHMM', 'Batch PMI']
The motivation behind these experiments is to investigate the performance of PMI and PHMM systems when trained on the word lists belonging to the same language family but compiled by different group of annotators. A successful experiment indicates that this approach of training a PMI matrix on ASJP 40 word lists can be applied to language families that have longer word lists but no cognate judgments.
