PDF Enhancements Tools for a Digital Library

Hatlapatka, Radim, Sojka, Petr

Similarity:

This paper describes several innovative PDF document enhancements and tools that can be used when building a digital library. The main result presented in this paper is the PDF re-compression tool, developed using the jbig2enc encoder called pdfJbIm. This re-compression tool enables the size of the original bitonal PDFs to be, on average, downsized by one third. Some modifications to the jbig2enc encoder that increase the compression ratio even further are also described here. Together...

Community Curation and Management of Mathematical Literature

Burns, John, Kerr, Nigel

Similarity:

JSTOR is one of the primary providers of scholarly mathematics texts, providing access to journals in mathematics and the sciences dating back to the mid 1600’s. There is now a critical mass of literature online and the task going forward is as much to provide tools to make it more accurate, more discoverable and more usable as it is to add more material. Often the tool building can be done by collaboration between information retrieval experts and practitioners in the field, irrespective...
