{"url":"/dataset/pcd","name":"PCD","full_name":"Poem Comprehensive Dataset","description_markdown":"The Arabic dataset is scraped mainly from الموسوعة الشعرية and الديوان. After merging both, the total number of verses is 1,831,770 poetic verses. Each verse is labeled by its meter, the poet who wrote it, and the age which it was written in. There are 22 meters, 3701 poets and 11 ages: Pre-Islamic, Islamic, Umayyad, Mamluk, Abbasid, Ayyubid, Ottoman, Andalusian, era between Umayyad and Abbasid, Fatimid, and finally the modern age. We are only interested in the 16 classic meters which are attributed to Al-Farahidi, and they comprise the majority of the dataset with a total number around 1.7M verses. It is important to note that the verses diacritic states are not consistent. This means that a verse can carry full, semi diacritics, or it can carry nothing.","description_withheld":null,"homepage":"https://hci-lab.github.io/LearningMetersPoems/","introduced_date":"2019-05-07","introduced_date_note":null,"introduced_by":{"paper":"/paper/190505700","title":"Learning meters of Arabic and English poems with Recurrent Neural Networks: a step forward for language understanding and synthesis","first_author":"Waleed A.
