Towards Verifiable Generation: A Benchmark for Knowledge-aware Language Model Attribution

ACL 2024findings

Although achieving great success, Large Language Models (LLMs) usually suffer from unreliable hallucinations. Although language attribution can be a potential solution, there are no suitable benchmarks and evaluation metrics to attribute LLMs to structured knowledge. In this paper, we define a new t…

Take a Break in the Middle: Investigating Subgoals towards Hierarchical Script Generation

ACL 2023findings

Goal-oriented Script Generation is a new task of generating a list of steps that can fulfill the given goal. In this paper, we propose to extend the task from the perspective of cognitive theory. Instead of a simple flat structure, the steps are typically organized hierarchically — Human often decom…
