In this study, we present Dice's coefficient on trigram profiles as metric for language similarity. As testbed, we focused on eight Philippine languages. No known language similarity value for these languages exists. Documents containing transcribed audio recordings, news articles, religious and literary texts were taken from an online corpus and u...
