Practical Comparable Data Collection for Low-Resource Languages via Images

• Paper: https://arxiv.org/abs/2004.11954

• Slides: https://madaan.github.io/res/artifacts/pml4dc-practical-data-collection.pdf

• We propose a method of curating high-quality comparable training data for low-resource languages without requiring that the annotators are bilingual. Our method involves using a carefully selected set of images as a pivot between the source and target languages by getting captions for such images in both languages independently. Human evaluations on the English-Hindi comparable corpora created with our method show that 81.1% of the pairs are acceptable translations, and only 2.47% of the pairs are not a translation at all. We further establish the potential of dataset collected through our approach by experimenting on two downstream tasks -- machine translation and dictionary extraction.

• Joint work with Shruti Rijhwani, Antonios Anastasopoulos, Yiming Yang, and Graham Neubig.

• Work to be presented as a poster at Practical ML for Developing Countries Workshop at ICLR 2020.

Task Instructions

• आपको एक वाक्य के साथ हर छवि का वर्णन करना होगा।
• छवि के वर्णन में शुद्ध हिंदी का उपयोग करना ज़रूरी नहीं हे | जैसा ठीक लगे लिखें |
• कृपया उन गतिविधियों, लोगों, जानवरों और वस्तुओं का सटीक विवरण प्रदान करें जिन्हें आप चित्र में देख रहे हें |
• प्रत्येक विवरण एक ही वाक्य का होना चाहिए।
• विवरण हिंदी में लिखा जाना चाहिए।
• संक्षिप्त होने का प्रयास करें।
• अगर किसी शब्द का हिंदी में मतलब ना पता हो तो उसे इंग्लिश में ही लिख दें |
• व्याकरण और वर्तनी पर ध्यान दें।
