– Improved ABBYY FineReader OCR Engine, IBM Adaptive OCR
– Post-processing and -correction modules
– Lexical resources for several European languages
 Support to the MLA community
– Best Practises & Strategic/Operational Guidelines
– Online Helpdesk
– Tool Showcases & Demonstrators
– Centre of Competence

Digitisation workflows
 Digitisation: a sequence of steps, from selection of analogue source
material to presentation of digital objects for end-users
 Workflow: software-based execution of a sequence without human

interaction
 Challenges and barriers
– Workflows are tailored to specific needs
– Lack of interoperability for applied software and input/outdata data
– Lack of collaboratively used and developed resources and expertise

Collaborative workflow development
 Workflow Development as a community-driven activity using an

experimental platform
 Scientific workflows: using web services representing individual
software modules (Shiyong Lu et al. 2009)
 Providing highly innovative and efficient tools to a wider community to
design workflows
 Technical staff providing the platform, conceptual/library staff
designing workflows
 Using Web 2.0 features to share and expand knowledge and
resources

Evaluation criteria
 OCR: correctly recognised characters/words
 Segmentation: correctly identified text and graphical regions
 Workflows: comparing workflows and identifiying most suitable
 Statistical and provenance data: e.g. processing time

Outlook
 Keys to success
– Joint effort by library and software development staff
– Usability of tools and platform
– Incentive to collaborative work
– Testing and adaptation of workflows
– Permanently tailoring and optimizing workflows
 Future work
– Demonstration of current (web) services
– Experimental platform as sustainable resource for a Centre of
Competence for the MLA community
