LeTS: Learning to Think-and-Search via Process-and-Outcome Reward Hybridization

EMNLP 2025

Large language models (LLMs) have demonstrated impressive capabilities in reasoning with the emergence of reasoning models like OpenAI-o1 and DeepSeek-R1. Recent research focuses on integrating reasoning capabilities into the realm of retrieval-augmented generation (RAG) via outcome-supervised reinf

CR-LLM: A Dataset and Optimization for Concept Reasoning of Large Language Models

ACL 2024findings

Concept reasoning is an important capability for models to understand the world. However, the existing datasets, such as concept extraction and concept generation, suffer from modeledge leakage and context leakage. To address these limitations, we construct a dataset of concept reasoning for large l…

SEGMENT+: Long Text Processing with Short-Context Language Models

EMNLP 2024main

There is a growing interest in expanding the input capacity of language models (LMs) across various domains. However, simply increasing the context window does not guarantee robust performance across diverse long-input processing tasks, such as understanding extensive documents and extracting detail…
