Efficient Multi-Agent Collaboration with Tool Use for Online Planning in Complex Table Question Answering

NAACL 2025findings

Complex table question answering (TQA) aims to answer questions that require complex reasoning, such as multi-step or multi-category reasoning, over data represented in tabular form. Previous approaches demonstrate notable performance by leveraging either closed-source large language models (LLMs) o…

Texts or Images? A Fine-grained Analysis on the Effectiveness of Input Representations and Models for Table Question Answering

ACL 2025finding

In table question answering (TQA), tables are encoded as either texts or images. Prior work suggests that passing images of tables to multi-modal large language models (MLLMs) performs comparably to using textual input with large language models (LLMs). However, the lack of controlled setups limits…

A Cost-Efficient Modular Sieve for Extracting Product Information from Company Websites

EMNLP 2024industry

Extracting product information is crucial for informed business decisions and strategic planning across multiple industries. However, recent methods relying only on large language models (LLMs) are resource-intensive and computationally prohibitive due to website structure differences and numerous n…

FREB-TQA: A Fine-Grained Robustness Evaluation Benchmark for Table Question Answering

NAACL 2024long

Table Question Answering (TQA) aims at composing an answer to a question based on tabular data. While prior research has shown that TQA models lack robustness, understanding the underlying cause and nature of this issue remains predominantly unclear, posing a significant obstacle to the development…

LLMs Beyond English: Scaling the Multilingual Capability of LLMs with Cross-Lingual Feedback

ACL 2024findings

To democratize large language models (LLMs) to most natural languages, it is imperative to make these models capable of understanding and generating texts in many languages, in particular low-resource ones. While recent multilingual LLMs demonstrate remarkable performance in such capabilities, these…

Is the Answer in the Text? Challenging ChatGPT with Evidence Retrieval from Instructive Text

EMNLP 2023short findings

Generative language models have recently shown remarkable success in generating answers to questions in a given textual context. However, these answers may suffer from hallucination, wrongly cite evidence, and spread misleading information. In this work, we address this problem by employing ChatGPT…

Python Code Generation by Asking Clarification Questions

ACL 2023long

Code generation from text requires understanding the user’s intent from a natural languagedescription and generating an executable code snippet that satisfies this intent. While recent pretrained language models demonstrate remarkable performance for this task, these models fail when the given natur…
