ChemScraper: Leveraging PDF Graphics Instructions for Molecular Diagram Parsing
Ayush Kumar Shah, Bryan Manrique Amador, Abhisek Dey +4
Most molecular diagram parsers recover chemical structure from raster images (e.g., PNGs). However, many PDFs include commands giving explicit locations and shapes for characters,…
Multimodal Search in Chemical Documents and Reactions
Ayush Kumar Shah, Abhisek Dey, Leo Luo +9
We present a multimodal search tool that facilitates retrieval of chemical reactions, molecular structures, and associated text from scientific literature. Queries may combine mole…
Mathematical Information Retrieval: Search and Question Answering
Richard Zanibbi, Behrooz Mansouri, Anurag Agarwal
Mathematical information is essential for technical work, but its creation, interpretation, and search are challenging. To help address these challenges, researchers have developed…
Local and Global Graph Modeling with Edge-weighted Graph Attention Network for Handwritten Mathematical Expression Recognition
Yejing Xie, Richard Zanibbi, Harold Mouchère
In this paper, we present a novel approach to Handwritten Mathematical Expression Recognition (HMER) by leveraging graph-based modeling techniques. We introduce an End-to-end model…
