- Abstract: Question answering on the hybrid context of tables and text (TATQA) is a critical task, with broad applications in data-intensive domains. However, existing TATQA datasets are limited to English, leading to several drawbacks: (i) They overlook the challenges of multilingual TAT-QA and cannot assess model performance in the multilingual setting. (ii) They do not reflect real-world scenarios where tables and texts frequently appear in non-English languages. To address the limitations, we propose the first multilingual TATQA dataset (MULTITAT). Specifically, we sample data from 3 mainstream TATQA datasets and translate it into 10 diverse languages. To align the model TATQA capabilities in English with other languages, we develop a baseline, Ours. Experimental results reveal that the performance on non-English data in MULTITAT drops by an average of 19.4% compared to English, proving the necessity of MULTITAT. We further analyze the reasons for this performance gap. Furthermore, Ours outperforms other baselines by an average of 3.3, demonstrating its effectiveness.

- The Challenge of Achieving Attributability in Multilingual Table-to-Text Generation with Question-Answer Blueprints [0.0]
Table-to-Text NLG is an excellent measure of models' reasoning abilities but is very challenging in the multilingual setting.
Intermediate planning techniques like Question-Answer (QA) blueprints have been shown to improve attributability on summarisation tasks.
This work explores whether QA blueprints make multilingual Table-to-Text outputs more attributable to the input tables.

Large language models (LLMs) showcase varied multilingual capabilities across tasks like translation, code generation, and reasoning.
