Abstract
Background: Prosody (rhyming words) is a connatural element of poetry, throughout its reach, across thousands of languages in the world. Since medieval era, the Indic poetry (principally the Hindi/Urdu poetry) has created an impactful flamboyance w.r.t the subjects, styles, and other creative aspects in poetry. Besides the message of heartfelt poetry, we see the Qafiya (i.e., rhyming words) is the core element, without which we may not consider anything Hindi/Urdu poetry but merely a piece of writing; alongside it, Radif (i.e., a phrasal suffix to qafiya) is also considered next to the intrinsic part in Ghazals. In this regard, the contributions of this paper are one–the development of an optimal technique for the prosodic (qafiya) suggestions/retrieval in Hindi/Urdu poetry; and two–the qafiya suggestions based on the attached subsequent radif. Methods: The work in this paper involves usage of a 13.46 M tokens tri-script corpus of poetry. Instead of phonetic value matching, the proposed methodology employs four different Edit Distances (i.e., Levenshtein, Damerau–Levenshtein, Jaro–Winkler, and Hamming distance) as the comparison measures for prosodic suggestions. Findings: The proposed work shows better results in comparison to ‘Qaafiya Dictionary’ powered by rekhta.org. Moreover, w.r.t the inter-metric similarity and running time Jaro–Winkler appears to be the most optimal algorithm for the rhyme suggestion, whereas the Levenshtein distance is the laziest technique. Novelty/Applications: This work benefits researchers of Indic natural language processing for lexical look-ups and analysis of creative literature, especially poetry.
Highlights
Throughout the history of the world and literature, the impression of poetry is beholding and profound
The proposed method is thoroughly tested with various words and compared with the Qaafiya Dictionary (QD) powered by Rekhta
We found that QD often fails to produce good results when the target word is bigger in length
Summary
Throughout the history of the world and literature, the impression of poetry is beholding and profound. Besides the message of heartfelt poetry, we see the Qafiya (i.e., rhyming words) is the core element, without which we may not consider anything Hindi/Urdu poetry but merely a piece of writing; alongside it, Radif (i.e., a phrasal suffix to qafiya) is considered next to the intrinsic part in Ghazals. In this regard, the contributions of this paper are one–the development of an optimal technique for the prosodic (qafiya) suggestions/retrieval in Hindi/Urdu poetry; and two–the qafiya suggestions based on the attached subsequent radif. Both languages appear at the 3rd place, as most spoken languages of the world, with 329.1M native speakers and 697.4M total speakers [19]
