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.
