Clipping Library

• Nikola Tesla Museum possesses a rich collection
  of newspaper clippings on work and life of Nikola
  Tesla
• The clipping library is collected by Nikola
  Tesla, supported by his personal secretary
• One part of the library is organized in books,
  while many clippings are not organized

3
Digital Library Prototype

• Digitization Group at Faculty of Mathematics
  approached the development of digital clipping
  library prototype
• Primary goals
• The problem analysis
• Recognition of appropriate solutions

4
Problems

• Significant variations in materials sources and
  qualities
• The data and metadata organization and modeling
• Data access

5
Differences in sources and preservation level

• Different digitization techniques provide the
  different results, depending on paper and print
  type and preservation level
• Different target formats are considered
• Digital image formats
• PDF
• DejaVu format

6
Data organization

• File systems are not appropriate
• Complex data and metadata access
• Limited search capabilities
• Databases allow
• Simpler access
• Advanced searching

7
Automatic text extraction

• Primary problems are
• Different languages
• Large varieties and high font stylization used in
  the corresponding time period
• Significantly low material quality, because of
  aging
• Different OCR systems are evaluated
• No OCR software satisfied, primarily because of
  the low material readability
• Significant amount of manual corrections is
  necessary

8
Searching

• The multiple criteria searching is essential,
  including searching by
• Metadata
• Caption
• Key words
• Publications
• Language
• Period
• The clipping content
• Manual corrections of text are essential
• The efficiency require the application of some
  indexing methods

9
The solution DBMS

• The prototype is based on DBMS IBM DB2
• Advanced SQL implementation
• Efficient handling of binary content
• High concurrency level
• High reliability
• Good experiences
• Free licensing terms

10
The solution User interface

• Web application concept is
• Rich in content and visual presentation
• Customizable
• Portable
• Relatively simple for implementing

11
The solution Application

• The library prototype is implemented in
  functional programming language Wafl
• Wafl is designed for automatic document
  generation and particularly customized for Web
  development
• Features very simple and efficient database access
