Following this thread initiated by @orph and @higgs - opening a new "tutorial" thread for development on English conversational model based on A Neural Conversational Model,Vinyals, O., & Le, Q. (2015) paper.
Using OpenSubtitle corpus (Jörg Tiedemann, 2009), English XML dump (19Gb, 323905 movies, 338M sentences) - consecutive sentences with following properties were extracted:
- first sentence ends with question mark
- second sentence has no question mark
- second sentence follows in the movie the first sentence by less than 20 seconds
The extracted pairs were additionally cleaned-up (detokenized, removal sound sequence like
(BANG), removal of too complex sentences, normalization of quotes), uniq-ed and shuffled.
This gives a 14M sentence corpus, and 10000 sentences for validation available here. Difference with OpenSubtitle corpus mentioned in the paper is that pairs are questions/answers while in their corpus, it contains any sequence of sentences. Note that there is no certitude that answers are actually answering the questions (answer can come from the same the same speaker, or change topic and/or scene in the movie).
