TableLLM: A Robust Large Language Model for Efficient Tabular Data Manipulation in Real-World Office Scenarios

Core Concepts

TableLLM is a 13-billion-parameter large language model purpose-built for proficiently handling a wide range of tabular data manipulation tasks, including query, update, merge, and chart operations, in both document-embedded and spreadsheet-embedded scenarios to cater to real-world office usage.

Abstract

The paper introduces TableLLM, a large language model (LLM) with 13 billion parameters, designed specifically for handling tabular data manipulation tasks in real-world office scenarios. The key highlights are:

Motivation and User Study:

Tabular data is ubiquitous in various industries, but specific table-related tasks can be laborious and error-prone.
The authors conducted an extensive user study with 507 participants across diverse professions to capture their requirements in real-world office scenarios.
The study revealed a preference for tasks like table query, revision, chart creation, and matching, as well as a need to handle both document-embedded and spreadsheet-embedded tabular data.

Proposed Approach:

The authors introduce a distant supervision method for training TableLLM, which includes a reasoning process extension strategy and a cross-way validation strategy to enhance the quality of the automatically generated training data.
The training of TableLLM utilizes distinct prompts for document-embedded and spreadsheet-embedded tabular data scenarios.

Evaluation and Results:

The authors have crafted a comprehensive benchmark to evaluate TableLLM's performance on both document-embedded and spreadsheet-embedded tabular data scenarios, covering query, update, merge, and chart operations.
Thorough evaluations demonstrate that TableLLM outperforms various existing general-purpose and tabular data-focused LLMs, particularly in the spreadsheet-embedded scenario.
The authors have publicly released the model checkpoint, source code, benchmarks, and a web application for user interaction.

Impact and Beneficial Groups:

The authors believe TableLLM has the potential to create a positive impact on both industrial developers and users by addressing a practical problem, providing high-quality open-source models, and offering a convenient web application service.

Stats

TableLLM outperforms GPT-3.5 and even GPT-4 in the spreadsheet-embedded tabular data scenario.
TableLLM achieves an impressive 80.83% accuracy on the authors' created benchmark with entirely distinct tabular data and questions from the training data, showcasing its robust generalization ability.
Incorporating extended reasoning processes and generated data into the training data yields performance boosts of up to 10.1% compared to using only the original training data.
The cross-way validation method outperforms same-way validation and self-check validation in terms of the quality of the automatically generated training data.
