WordCorr (Experimental)

Current version: 2.0, released November 4, 2004

Wordcorr builds on WordSurv's data management model for inputting word lists and assigning grouping tags to them. It goes beyond WordSurv in that it forms and organizes all the correspondence sets implied by the linguist's judgments of comparability. From these, linguists can construct a detailed picture of the detailed processes by which diversification within a language family took place, backed up by massive evidence.

Data input is in several forms. The most straightforward is input of full Unicode IPA from the keyboard, using a new method that takes about a minute to learn, requires no reference to complex keyboard tables, and does not require the fingers to leave the keyboard. Wordcorr users can also share data files, which are managed as compressed XML. There is an importer for data files from the early versions of WordSurv; for recent versions the PalmSurv Converter handles importation. There is also a utility on SourceForge that contains a spreadsheet template from which a Python script produces a Wordcorr XML file for regular importation. There is a similar path for the spreadsheet template through the PalmSurv Converter. The Python script can also be modified to provide importation from other computer formats.

Initial development of Wordcorr was a cooperative effort by SIL, the University of Hawai`i at Mānoa, and DataHouse Inc., a professional software house, funded by the U.S. National Science Foundation. Continued maintenance is as an Open Source project on
