Parallel corpora are data sets created by representing sentences with the same meaning in different languages. One of the most important elements that determine the quality in machine translation systems is the parallel corpora created in large quantities and with high quality. Such data for the Turkish – English language pair are generally insufficient. In this study, a large amount of parallel corpora has been created that can be used for academic translations between Turkish and English languages. While creating this data set, the abstracts of the postgraduate theses were used. The best matches were obtained using sentence alignment algorithms such as Vecalign and Hunalign. As a result of the studies, 1M parallel sentence pairs were obtained. In addition, an Bi-LSTM-based translation system was created to measure the quality of the obtained data. The created model obtained 15.8 Bleu points with zero-shot learning method on the TED (Tr-En) test set.

Türkçe-İngilizce Akademik Çeviriler için Paralel Corpora Oluşturulması

Öz

Paralel corpora aynı anlama gelen cümlelerin farklı dillerde temsil edilmesiyle oluşturulan veri setleridir. Makine çeviri sistemlerinde kaliteyi belirleyen en önemli öğelerden birisi büyük miktarda ve yüksek kalitede oluşturulmuş paralel corporadır. Türkçe – İngilizce dil çifti için oluşturulan bu tür veriler genellikle yetersizdir. Bu çalışmada Türkçe – İngilizce dilleri arasında akademik çeviriler için kullanılabilecek büyük miktarda paralel corpora oluşturulmuştur. Bu veri seti oluşturulurken lisansüstü tezlerinin özet kısımları kullanılmıştır. Vecalign ve Hunalign gibi cümle hizalama algoritmaları kullanılarak en iyi eşleştirmeler elde edilmiştir. Yapılan çalışmalar sonucunda 1M paralel cümle çifti elde edilmiştir. Ayrıca elde edilen verinin kalitesini ölçebilmek için Bi-LSTM tabanlı çeviri sistemi oluşturulmuştur. Oluşturulan model TED(Tr-En) test seti üzerinde sıfır vuruş öğrenme (zero shot learning) yöntemiyle 15.8 Bleu puanı elde etmiştir.
