Trove addicts can find out how it all works in "Scaling up: the
technology behind the NLA's newspaper digitisation and the Trove search
service" by Kent Fitch, at the Australian Computer Society Canberra
Branch Forum, 6 December 2011: 

Australian Computer Society, Canberra Branch Forum

Scaling up: the technology behind the NLA's newspaper digitisation and
the Trove search service

Each week, the NLA's Trove search service, receives around 200K "real"
unique visitors and delivers almost 3M page views. Although Trove
describes a diverse set of 250M items, its most popular content are
digitised Australian newspaper articles.

This talk will describe the technology behind Trove in general then
focus on the technical aspects of digitising and full-text-indexing over
60M newspaper articles, discussing aspects of image formats and
processing, OCR correction, the scalability of the Lucene text indexing
library, search result ranking, and how commodity SSD has made the
unthinkable both easy and cheap.

The presentation will encourage audience interaction and questions.


Kent Fitch has worked as a programmer for over 30 years. Since 1982 he
has been a principal of the Canberra software development company,
Project Computing Pty Ltd. He has developed many commercial systems and
communications packages and custom software for many clients. In the
past ten years, his work has focused on library-related systems
including AustLit, NLA Newspapers Digitisation, and Trove.
