CypherBench: Towards Precise Retrieval over Full-scale Modern Knowledge Graphs in the LLM Era

ACL 2025long

Retrieval from graph data is crucial for augmenting large language models (LLM) with both open-domain knowledge and private enterprise data, and it is also a key component in the recent GraphRAG system (CITATION). Despite decades of research on knowledge graphs and knowledge base question answering,…

SQUAB: Evaluating LLM robustness to Ambiguous and Unanswerable Questions in Semantic Parsing

EMNLP 2025

Large Language Models (LLMs) have demonstrated robust performance in Semantic Parsing (SP) for well-defined queries with unambiguous intent and answerable responses. However, practical user questions frequently deviate from these ideal conditions, challenging the applicability of existing benchmarks

QATCH: Benchmarking SQL-centric tasks with Table Representation Learning Models on Your Data

NeurIPS 2023poster

Table Representation Learning (TRL) models are commonly pre-trained on large open-domain datasets comprising millions of tables and then used to address downstream tasks. Choosing the right TRL model to use on proprietary data can be challenging, as the best results depend on the content domain, sch…
