1 IMPACT is supported by the European Community under the FP7 ICT Work Programme. The project is coordinated by the National Library of the Netherlands. Hildelies Balk, IMPACT Project Director, KB National Library of the Netherlands IMPACT: Challenges and solutions

2 IMPACT is supported by the European Community under the FP7 ICT Work Programme. The project is coordinated by the National Library of the Netherlands. 2 Overview of this presentation  Challenges in digitisation of historical full text  IMPACT objectives  Approach  Achievements  Better, Faster, Cheaper  The IMPACT Centre of Competence

3 IMPACT is supported by the European Community under the FP7 ICT Work Programme. The project is coordinated by the National Library of the Netherlands. 3 The Content  Shared vision in Europe: all cultural heritage available in digital form in this decade  Billions of pages of historical (pre-1900) text in libraries in Europe  Users expect full text to search, tag and re-use  Just image and metadata not enough

7 IMPACT is supported by the European Community under the FP7 ICT Work Programme. The project is coordinated by the National Library of the Netherlands. 7 Answering the challenges – IMPACT IMPACT – Improving Access to Text (2008-2011)  Large-scale integrating research project  Consortium of 26 partners  Coordinated by the National Library of the Netherlands (KB)  Co-funded by EU (FP7 ICT Work Programme) Objectives: Significantly improve mass digitisation of historical printed text by:  Innovating OCR software and language technology  Sharing expertise and building capacity across Europe  Providing facilities for future research and development

8 IMPACT is supported by the European Community under the FP7 ICT Work Programme. The project is coordinated by the National Library of the Netherlands. 8 IMPACT - Approach  Content holders, researchers and industry work together to find solutions  Based on real life problems in digitisation  Tackle each step in the digitisation workflow from scan to full text Image enhancement: Binarisation noise removal geometrical defects correction NSCR,USAL, ABBYY OCR ABBY FR IBM Adaptive Dictonaries/interface LMU,INL Experimental engines USAL,NCSR,UIBK  Segmentation and Document analysis USAL,NCSR,ABBYY Post correction and Enrichment CONCERT IBM Error Profiler LMU Language resources 9 partners Document Understanding Platform UIBK Preparation and scanning: guidelines and case studies All partners -/-/-/-/-/- /-/-/-/-/- /-/-/-/-/- /-/-/-/-/- /-/-/-/-/-

9 IMPACT is supported by the European Community under the FP7 ICT Work Programme. The project is coordinated by the National Library of the Netherlands. 9 IMPACT – Approach continued  Tools to be coupled in Interoperability Framework  Tested with Evaluation tools and metrics  Against representative set of test data with Ground Truth  Basis for further research and development

10 IMPACT is supported by the European Community under the FP7 ICT Work Programme. The project is coordinated by the National Library of the Netherlands. 10 IMPACT Achievements: summary  On market: Improved commercial OCR  Ready for testing in productive environment: –Adaptive OCR engine –Tools for OCR correction with volunteer involvement –Computerlexica for nine languages –Digitisation Framework with evaluation tools and dataset –Knowledge bank with guidelines and learning resources –Service for for print space recognition  For future development: –Novel Approaches to preprocessing, OCR and post correction –New language resources with Tools for lexicon building  Centre of Competence for digitisation to start 1 january 2012  Added value: Unique network bringing together experts from different communities

12 IMPACT is supported by the European Community under the FP7 ICT Work Programme. The project is coordinated by the National Library of the Netherlands. 12 Results: Better and Faster  All tools evaluated in different testscenarios on IMPACT dataset  All individual tools show improvement on SOA  Some examples of results – there is more! Image enhancement: Binarisation noise removal geometrical defects correction NSCR,USAL, ABBYY OCR ABBY FR IBM Adaptive Dictonaries/interface LMU,INL Experimental engines USAL,NCSR,UIBK  Segmentation and Document analysis USAL,NCSR,ABBYY Post correction and Enrichment CONCERT IBM Error Profiler LMU Language resources 9 partners Document Understanding Platform UIBK Better:hybrid line segmentation on 2700 text lines SOA 90,9 →98,8% IMPACT Better:recognition old fonts FR9→FR10 improved 25% Better, faster:Adaptive OCR on small testset halves FOM (post processing level required) Faster: CONCERT increases correction speed up to 40% Faster: postcorrection with Error Profiler up to 2,7x faster than without Better: page split detected on 3.000 images from dataset: SOA 73%→94% IMPACT Better: language resources show improvement for all 9 languages

13 IMPACT is supported by the European Community under the FP7 ICT Work Programme. The project is coordinated by the National Library of the Netherlands. 13 Results: Cheaper Industry in IMPACT:  ABBYY FR Historic Fonts Module more than 10 times cheaper; more flexible rates overall  IBM Adaptive OCR and CONCERT: flexible rates Research in IMPACT:  Key Language resources free  All tools by research partners free for research and free/low rates on non commercial use (individual licensing required), subject to volume, kind of use and material, support etc. Framework:  Digitisation Framework free and open source  Open source wrapper to plug in other (free) tools  Fruitful contacts with new open source tool providers  Increasing number of IMPACT tools Open Source

14 IMPACT is supported by the European Community under the FP7 ICT Work Programme. The project is coordinated by the National Library of the Netherlands. 14 Benefits for the Digital Library  Reminder: IMPACT is a RESEARCH Project  Fitness for productive use of tools already exceeds expectations  Rough average of all tests by developers on IMPACT dataset indicates consisten improvement of up to 20% Waht does this mean for the Library objectives:  better access, faster and cheaper production →Measured by: retrieval, time and money spent  Q1-3 2011: Pilots carried out in house → focus on user feedback and implementation issues  Q4 and beyond: pilots planned to measure all aspects First test in productive environment: ABBYY FR 10 with Dutch lexikon on Dutch 17th C Newspapers  20% increase in Word Accuracy (LD)  15% improvement in word retrieval

15 IMPACT is supported by the European Community under the FP7 ICT Work Programme. The project is coordinated by the National Library of the Netherlands. 15 Benefits for the End User  Users of the Libraries: –researchers in the humanities –Greater public  End user Only interest: retrieval = words searched and found correctly  Preliminary results of OCR combined with dictionary on difficult material (17th century newspaper)  indicate already 15% increase of words found  →For 1 M words this means 150 K more words found  And this is just the beginning
