This paper explores three different methods of learning to map variant word form (dialectal or diachronic) to standard ones from a limited parallel corpus of standard and variant texts, given that a computational description of the standard morphology is available.

This paper investigates a diachronic change that has taken place in the production and perception of the “rising” tone in Bangkok Thai, comparing data collected in the 1960’s and 1970’s with data collected 2004 to 2006. Regarding production, several studies have found that the abrupt pitch rise that had characterized the rising tone in earlier studies is now curtailed, such that the pitch of th...

We present a method of finding and analyzing shifts in grammatical relations found in diachronic corpora. Inspired by the econometric technique of measuring return and volatility instead of relative frequencies, we propose them as a way to better characterize changes in grammatical patterns like nominalization, modification and comparison. To exemplify the use of these techniques, we examine a ...
