Spiral of Silences: How is Large Language Model Killing Information Retrieval? -- A Case Study on Open Domain Question Answering

1 code implementation16 Apr 2024 Xiaoyang Chen, Ben He, Hongyu Lin, Xianpei Han, Tianshu Wang, Boxi Cao, Le Sun, Yingfei Sun

The practice of Retrieval-Augmented Generation (RAG), which integrates Large Language Models (LLMs) with retrieval systems, has become increasingly prevalent.

ToolAlpaca: Generalized Tool Learning for Language Models with 3000 Simulated Cases

1 code implementation8 Jun 2023 Qiaoyu Tang, Ziliang Deng, Hongyu Lin, Xianpei Han, Qiao Liang, Boxi Cao, Le Sun

Existing approaches to tool learning have either primarily relied on extremely large language models, such as GPT-4, to attain generalized tool-use abilities in a zero-shot manner, or utilized supervised learning to train limited scopes of tools on compact models.

The Life Cycle of Knowledge in Big Language Models: A Survey

1 code implementation14 Mar 2023 Boxi Cao, Hongyu Lin, Xianpei Han, Le Sun

Knowledge plays a critical role in artificial intelligence.

Pre-training to Match for Unified Low-shot Relation Extraction

1 code implementation ACL 2022 Fangchao Liu, Hongyu Lin, Xianpei Han, Boxi Cao, Le Sun

Low-shot relation extraction~(RE) aims to recognize novel relations with very few or even no samples, which is critical in real scenario application.

Can Prompt Probe Pretrained Language Models? Understanding the Invisible Risks from a Causal View

1 code implementation ACL 2022 Boxi Cao, Hongyu Lin, Xianpei Han, Fangchao Liu, Le Sun

Prompt-based probing has been widely used in evaluating the abilities of pretrained language models (PLMs).

Knowledgeable or Educated Guess? Revisiting Language Models as Knowledge Bases

1 code implementation ACL 2021 Boxi Cao, Hongyu Lin, Xianpei Han, Le Sun, Lingyong Yan, Meng Liao, Tong Xue, Jin Xu

Previous literatures show that pre-trained masked language models (MLMs) such as BERT can achieve competitive factual knowledge extraction performance on some datasets, indicating that MLMs can potentially be a reliable knowledge source.
