Leveraging Reaction-aware Substructures for Retrosynthesis Analysis

1 code implementation12 Apr 2022 Lei Fang, Junren Li, Ming Zhao, Li Tan, Jian-Guang Lou

In this paper, we propose a substructure-level decoding model, where the substructures are reaction-aware and can be automatically extracted with a fully data-driven approach.

A Split-and-Recombine Approach for Follow-up Query Analysis

1 code implementation IJCNLP 2019 Qian Liu, Bei Chen, Haoyan Liu, Lei Fang, Jian-Guang Lou, Bin Zhou, Dongmei Zhang

To leverage the advances in context-independent semantic parsing, we propose to perform follow-up query analysis, aiming to restate context-dependent natural language queries with contextual information.
