Generalizing Experience for Language Agents with Hierarchical MetaFlows

NeurIPS 2025poster

Recent efforts to employ large language models (LLMs) as agents have demonstrated promising results in a wide range of multi-step agent tasks. However, existing agents lack an effective experience reuse approach to leverage historical completed tasks. In this paper, we propose a novel experience reu…

WorkflowLLM: Enhancing Workflow Orchestration Capability of Large Language Models

ICLR 2025poster

Recent advancements in large language models (LLMs) have driven a revolutionary paradigm shift in process automation from Robotic Process Automation to Agentic Process Automation by automating the workflow orchestration procedure based on LLMs. However, existing LLMs (even the advanced OpenAI GPT-4o…

LogicST: A Logical Self-Training Framework for Document-Level Relation Extraction with Incomplete Annotations

EMNLP 2024main

Document-level relation extraction (DocRE) aims to identify relationships between entities within a document. Due to the vast number of entity pairs, fully annotating all fact triplets is challenging, resulting in datasets with numerous false negative samples. Recently, self-training-based methods h…

Boosting Document-Level Relation Extraction by Mining and Injecting Logical Rules

EMNLP 2022main

Document-level relation extraction (DocRE) aims at extracting relations of all entity pairs in a document. A key challenge to DocRE lies in the complex interdependency between the relations of entity pairs. Unlike most prior efforts focusing on implicitly powerful representations, the recently propo…

CETA: A Consensus Enhanced Training Approach for Denoising in Distantly Supervised Relation Extraction

COLING 2022main

Distantly supervised relation extraction aims to extract relational facts from texts but suffers from noisy instances. Existing methods usually select reliable sentences that rely on potential noisy labels, resulting in wrongly selecting many noisy training instances or underutilizing a large amount…

Key Mention Pairs Guided Document-Level Relation Extraction

COLING 2022main

Document-level Relation Extraction (DocRE) aims at extracting relations between entities in a given document. Since different mention pairs may express different relations or even no relation, it is crucial to identify key mention pairs responsible for the entity-level relation labels. However, most…
