WordSurv (Supported)

See the new WordSurv site for up-to-date information.

Current version: 6.0, released December 2006

A typical language survey may involve determining linguistic relationships through the comparison of word lists. WordSurv is designed to aid in this task. It functions in three main areas: (1) entry and maintenance of word lists and cognate decisions, (2) computation of lexicostatistic and phonostatistic measures of similarity, and (3) output of data and results in various formats. WordSurv also supports the COMPASS algorithm to aid in comparative reconstruction.

PalmSurv may be used for wordlist transcription into a PalmOS handheld computer.

Notice: Wordsurv version 7 is due for release in 2011. See the WordSurv site hosted by Taylor University for more info.
