X-Score: Automatic Evaluation of Machine Translation Grammaticality
Olivier Hamon, Martin Rajman · 2006
In this paper we report an experiment of an automated metric used to analyze the grammaticality of machine translation output.The approach (Rajman, Hartley, 2001) is based on the distribution of the linguistic information within a translated text, which is supposed similar between a learning corpus and the translation.This method is quite inexpensive, since it does not need any reference translation.First we describe the experimental method and the different tests we used.Then we show the promising results we obtained on the CESTA 1 data, and how they correlate well with human judgments.
