  • (Oct) SymbolScraper Server (update). Our SymbolScraper tool for extracting text and graphics from PDF files  has been rewritten, and made faster (including the addition of a docker container).
  • (Sept) MathSeer extraction pipeline released. This tool extracts formula locations and content in PDF documents. The pipeline is available from GitLab, and includes improved versions of SymbolScraper, ScanSSD (now, ScanSSD-XYc), and QD-GGA. The pipeline was prepared by Ayush K. Shah, Abhisek Dey, Matt Langsenkamp, and Prof. Zanibbi.
