Submission + - Ancient Languages Reconstructed by Computers (

halls-of-valhalla writes: "Researchers have developed a new software which can be used to reconstruct dead, ancient languages using probabilistic models of sound change.

This new software was tested by taking 637 Austronesian languages currently spoken in Asia and the Pacific, and attempting to reconstruct the ancient languages they're based on. The system was found to have provided a relatively accurate, large-scale automatic reconstruction of the protolanguages. A language believed to be roughtly seven thousand years old was reconstructed using a database of 142,000 words.

When compared to the results of linguists specializing in Austronesian languages, more 85% of the system's reconstructions were found to be within one character of the manual reconstruction. These are very promising results, however a linguist is still able to produce a higher accuracy, so this will be likely to become a tool used by linguists rather than a replacement for them."

The solution of this problem is trivial and is left as an exercise for the reader.
