Bartošek, Miroslav, Kovář, Petr, Šárfy, Martin

Similarity:

The aim of the DML-CZ project (2005–2009 — Czech Academy of Sciences, Masaryk University in Brno, Charles University in Prague, Czech Republic) is to investigate, develop and apply techniques, methods and tools that would allow the creation of the Czech Digital Mathematics Library. The most important tool developed and used in the course of the project is the Metadata Editor — a complex web-based system supporting all essential steps in the development of the article oriented digital...

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...

From Pixels and Minds to the Mathematical Knowledge in a Digital Library

Sojka, Petr, Rákosník, Jiří

Similarity:

Experience in setting up a workflow from scanned images of mathematical papers into a fully fledged mathematical library is described on the example of the project Czech Digital Mathematics Library DML-CZ. An overview of the whole process is given, with description of all main production steps. DML-CZ has recently been launched to public with more than 100,000 digitized pages.
