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
