We present B LAST, an open source tool for error analysis of machine translation (MT) output. We believe that error analysis, ., to identify and classify MT errors, should be an integral part of MT development, since it gives a qualitative view, which is not obtained by standard evaluation methods. B LAST can aid MT researchers and users in this process, by providing an easy-to-use graphical user interface. | Blast a Tool for Error Analysis of Machine Translation Output Sara Stymne Department of Computer and Information Science Linkoping University Linkoping Sweden Abstract We present BLAST an open source tool for error analysis of machine translation MT output. We believe that error analysis . to identify and classify MT errors should be an integral part of MT development since it gives a qualitative view which is not obtained by standard evaluation methods. BLAST can aid MT researchers and users in this process by providing an easy-to-use graphical user interface. It is designed to be flexible and can be used with any MT system language pair and error typology. The annotation task can be aided by highlighting similarities with a reference translation. 1 Introduction Machine translation evaluation is a difficult task since there is not only one correct translation of a sentence but many equally good translation options. Often machine translation MT systems are only evaluated quantitatively . by the use of automatic metrics which is fast and cheap but does not give any indication of the specific problems of a MT system. Thus we advocate human error analysis of MT output where humans identify and classify the problems in machine translated sentences. In this paper we present Blast 1 a graphical tool for performing human error analysis from any MT system and for any language pair. Blast has a graphical user interface and is designed to be easy The BiLingual Annotation Annotator Analysis Support Tool available for download at http . se sarst blast 56 and intuitive to work with. It can aid the user by highlighting similarities with a reference sentence. Blast is flexible in that it can be used with output from any MT system and with any hierarchical error typology. It has a modular design allowing easy extension with new modules. To the best of our knowledge there is no other publicly available tool for MT error annotation. Since we .
