 ### Dataset Summary
 
-TBA
+Opusparcus is a paraphrase corpus for six European languages: German,
+English, Finnish, French, Russian, and Swedish. The paraphrases are
+extracted from the OpenSubtitles2016 corpus, which contains subtitles
+from movies and TV shows.
+
+The data in Opusparcus has been extracted from OpenSubtitles2016
+(http://opus.nlpl.eu/OpenSubtitles2016.php), which is in turn based on
+data from http://www.opensubtitles.org/.
+
+For each target language, the Opusparcus data have been partitioned
+into three types of data sets: training, validation and test sets. The
+training sets are large, consisting of millions of sentence pairs, and
+have been compiled automatically, with the help of probabilistic
+ranking functions. The development and test sets consist of sentence
+pairs that have been annotated manually; each set contains
+approximately 1000 sentence pairs that have been verified to be
+acceptable paraphrases by two indepedent annotators.
