TVsub: DCU-Tencent Chinese-English Dialogue Corpus

The data are used in our AAAI-18 paper Translating Pro-Drop Languages with Reconstruction Models.

The corpus is designed to be dialogue domain and parallel data with larger-context information for research purpose. More than two million sentence pairs were extracted from the subtitles of television episodes.

Within the corpus, sentences are generally short and the Chinese side contains many examples of dropped pronouns (DPs). Therefore, the corpus was initially designed for pro-drop language translation task, and the related paper (Translating Pro-Drop Languages with Reconstruction Models) was accepted by AAAI 2018 conference.

Actually, the corpus can be also used for various translation tasks such as larger-context MT (Exploiting Cross-Sentence Context for Neural Machine Translation; Learning to Remember Translation History with a Continuous Cache).

Novelty

The differences to other existing bilignaul subtitle corpora are as follows:

  • We only extract subtitles of television episodes instead of movie ones. The vocabulary in movies is more sparsity than that in TV series. To aviod the long-tail problems, we use TV series data for MT tasks.

  • We pre-processed the extracted data using a number of in-house scripts including sentence boundary detection and bilingual sentence alignment etc. Thus, we obtained a more cleaner, better-aligned, high-quality corpus.

  • We keep the larger-context information instead of disordering sentences. Thus, you can mine useful discourse information from the previous or following sentences for MT.

  • We randomly select two complete television episodes as the tuning set, and another two episodes as the test set. We manually create multiple references for them.

  • In order to re-implement our AAAI-18 paper (Translating Pro-Drop Languages with Reconstruction Models), we also released the +DP corpus, in which the Chinese sentences are automatically labelled with DPs using alignment information.
