Poetry to Prose Conversion in Sanskrit as a Linearisation Task: A Case for Low-Resource Languages (P19-1)
Copied to clipboard
| Challenge: | Obtaining the proper word ordering, called as the prose ordering, from a verse is often considered a task which requires linguistic expertise. |
| Approach: | They propose a word ordering (linearisation) task that ignores the word arrangement at the verse side. |
| Outcome: | The proposed model outperforms current models in word ordering for the translation task in Sanskrit. |
Keep it Surprisingly Simple: A Simple First Order Graph Based Parsing Model for Joint Morphosyntactic Parsing in Sanskrit (2020.emnlp-main)

| Challenge: | Morphologically rich languages benefit from joint processing of morphology and syntax, as compared to pipeline architectures. |
| Approach: | They propose a graph-based model for joint morphological parsing and dependency parser in Sanskrit using the Energy based model framework. |
| Outcome: | The proposed model outperforms standalone morphological parsers in morphology and syntax parsing, and in dependency parser. |

| Challenge: | a structured prediction framework is proposed to solve word segmentation and morphological tagging tasks in a free word order language. |
| Approach: | They propose a structured prediction framework that jointly solves word segmentation and morphological tagging tasks in Sanskrit. |
| Outcome: | The proposed model outperforms the state of the art with an F-Score of 96.92 (percentage improvement of 7.06%) while using less than one tenth of the task-specific training data. |

| Challenge: | Multi-component compounding is a prevalent phenomenon in Sanskrit, and understanding the implicit structure of a compound is crucial for deciphering its meaning. |
| Approach: | They propose a task to identify nested spans of a multi-component compound and decode the implicit semantic relations between them. |
| Outcome: | The proposed framework surpasses the best baseline framework with an average improvement of 13.1 points in terms of Labeled Span Score and 5-fold enhancement in inference efficiency. |
