Zusammenfassung

This work investigates situations in the decoding process of Phrase-based SMT that cause particular errors on the output of the translation. A set of translations post-edited by professional translators is used to automatically identify errors based on edit distance. Binary classifiers predicting the sentence-level existence of an error are fitted with Logistic Regression, based on features from the decoding search graph. Models are fitted for 3 common error types and 6 language pairs. The statistically significant coefficients of the logistic function are used to analyze parts of the decoding process that are related to the particular errors.
