  Research seminar presentation of Galaxy and how it can be applied to a wide range of applications given as part of the Dublin Computational Linguistics Research Seminars (DCLRS) series. The audience for this talk consisted of academics and students with various specialties and led to some discussions regarding using Galaxy in the new multi-million euro research partnership funded by Science Foundation Ireland (SFI) that will develop the next generation of high tech automatic language translation (NGL CSET).
