PEARL framework enhances multi-hop table retrieval for LLMs

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced PEARL, a novel framework designed to improve multi-hop table retrieval for large language models. Unlike previous methods that encode entire tables, PEARL utilizes a training-free approach by vertically partitioning sub-tables and generating multi-hop queries offline. This method encodes relevant columns into vertically partitioned units, enabling effective retrieval across multiple tables without requiring query-time LLM inference. Experiments demonstrate that PEARL significantly outperforms existing techniques, achieving up to a 30.05% increase in R@2 on 3-hop queries. AI

IMPACT Improves LLM capabilities in structured data retrieval and reasoning.

    PEARL: Front-Loading Relational Chains for Multi-Hop Table Retrieval

    While large language models (LLMs) have shown strong capabilities in tabular reasoning, retrieving relevant tables remains challenging due to the fragmented and relational structure of real-world data. Existing work typically relies on whole table representations that overlook cr…
