Preface to Proceedings of the 12th European Workshop on Natural Language Generation (ENLG 2009)

We are pleased to present the Proceedings of the 12th European Workshop on Natural Language Generation (ENLG 2009). ENLG 2009 was held in Athens, Greece, as a workshop at the 12th Conference of the European Chapter of the Association for Computational Linguistics (EACL 2009). Following our call, we received 37 submissions (both long and short) of which 14 long papers and 10 short papers were accepted after a careful reviewing process. These Proceedings include the final versions of the accepted papers. In addition, the papers associated with the TUNA Generation Challenge are included in these proceedings.
