OpenChemIE: An Information Extraction Toolkit For Chemistry Literature

1 code implementation1 Apr 2024 Vincent Fan, Yujie Qian, Alex Wang, Amber Wang, Connor W. Coley, Regina Barzilay

Our machine learning models attain state-of-the-art performance when evaluated individually, and we meticulously annotate a challenging dataset of reaction schemes with R-groups to evaluate our pipeline as a whole, achieving an F1 score of 69. 5%.

Predictive Chemistry Augmented with Text Retrieval

1 code implementation8 Dec 2023 Yujie Qian, Zhening Li, Zhengkai Tu, Connor W. Coley, Regina Barzilay

Conventionally, chemoinformatics models are trained with extensive structured data manually extracted from the literature.

GLM: General Language Model Pretraining with Autoregressive Blank Infilling

9 code implementations ACL 2022 Zhengxiao Du, Yujie Qian, Xiao Liu, Ming Ding, Jiezhong Qiu, Zhilin Yang, Jie Tang

On a wide range of tasks across NLU, conditional and unconditional generation, GLM outperforms BERT, T5, and GPT given the same model sizes and data, and achieves the best performance from a single pretrained model with 1. 25x parameters of BERT Large , demonstrating its generalizability to different downstream tasks.

GraphIE: A Graph-Based Framework for Information Extraction

2 code implementations NAACL 2019 Yujie Qian, Enrico Santus, Zhijing Jin, Jiang Guo, Regina Barzilay

Most modern Information Extraction (IE) systems are implemented as sequential taggers and only model local dependencies.

A Probabilistic Framework for Location Inference from Social Media

no code implementations23 Feb 2017 Yujie Qian, Jie Tang, Zhilin Yang, Binxuan Huang, Wei Wei, Kathleen M. Carley

In this paper, we formalize the problem of inferring location from social media into a semi-supervised factor graph model (SSFGM).
