1 2002 September -- ejk/UF RESEARCH TOPICS Web-Interface Performance DTD Extensibility Imaging Distillation Other topics?

2 2002 September -- ejk/UF CONTEXT Image Only Pilots Australian Periodical Publications, 1840-1845 National Library of New Zealand. Papers Past Image & Indexing/Tagging Pilot University of Florida. Caribbean Newspaper Imaging Project University of Florida. Florida Newspaper Project Image & OCR Pilots Lambrakis Press Archives ProQuest. Historical Newspapers™ TIDEN Project : a Nordic Digital Newspaper Library Olive Software Pilot The British Library

3 2002 September -- ejk/UF WEB-INTERFACE PERFORMANACE Primary Purpose: Characterize the bias of individuals conducting study Products: How to use ActivePaper TM to Your Advantage Integration with CONTENTdm, XPAT 5.0, other Alternate deliverable images Centralized service – Distributed content – Variable platforms

4 2002 September -- ejk/UF DTD EXTENSIBILITY Primary Purpose: Assess the XML against established newspaper uses Products: How to use ActivePaperTM to Your Advantage Document the XML as a public DTD Establish a maintenance authority Provide for extension of the DTD Automation for extended tagging How to construct a style sheet Integration with CONTENTdm, XPAT 5.0, other Define issues per the Economic Model

5 2002 September -- ejk/UF IMAGING Directory Structure and File Naming Archival Formats Optimized Imaging

6 2002 September -- ejk/UF IMAGING: Directory Structure and File Naming Primary Purpose: Recommended practices Products: Methods for dealing with anomalies Automated name capture during imaging

7 2002 September -- ejk/UF IMAGING: Archival Formats Primary Purpose: Description of file formats & their characteristics for archive, distillation, and distribution Products: Preservation metadata Anticipate migration Schedule & fee structure for inspection & migration Strategy for format migrations & emulation

8 2002 September -- ejk/UF IMAGING: Optimized Imaging Primary Purpose: Best practices for microfilming and digitizing (quantitative assessments) Film reduction ratio Evenness of illumination on film Film background density Quality Index & DPI/PPI Skew Color-space & Bit-depth Image density/black & white points Despeckling and Sharpening Image restoration methods

9 2002 September -- ejk/UF IMAGING: Optimized Imaging Environments: Operating System Scanning Hardware Lighting and Light Filtration Post-processing Other? Other Products: Control target for OCR assessment Revision: RLG Preservation Microfilming Guidelines

10 2002 September -- ejk/UF DISTILLATION Document Zoning Optical Character Recognition

11 2002 September -- ejk/UF DISTILLATION: Document Zoning Primary Purpose: Confirm assumptions re: document zoning OCR has difficulty processing large letters Smaller zone yield more accurate text Products: Establish reference to the... PDF (fully scaled) TIFF Other derivative file formats (fully scaled)

12 2002 September -- ejk/UF DISTILLATION: OCR Primary Purpose: Provide quantitative OCR accuracy information Areas of Investigation: Distillation Source Images Language and Fonts Column & Line Density Relative Density/Contrast Text Curvature and Other Defects

13 2002 September -- ejk/UF DISTILLATION: OCR Primary Purpose: Predict accuracy contingent upon source document (printing technologies & filming standards) Test-Set Characterization: Source type (newspaper or microfilm) Production date (technologies & standards used) Additional Products: Best practices Accuracy : Cost – Matrix Distillation Source Images

14 2002 September -- ejk/UF DISTILLATION: OCR Language and Fonts Primary Purpose: Demonstrate ability to distill languages, character sets & fonts Test-Set Characterization: Language & character set groups Font face & font size groups Regional variant spellings Additional Products: Olive Software Speaks Your Language How Olive Software Learns Your Lingo Stylized text recognition & distillation guide

15 2002 September -- ejk/UF DISTILLATION: OCR Column & Line Density Primary Purpose: Demonstrate ability to distill compact text Test-Set Characterization: Pre-1900 newspapers Advertisement pages Pages predominantly 8 pt. type or less Pages with less than 1 mm space between lines Pages with characters spaced at or below ⅓ mm

16 2002 September -- ejk/UF DISTILLATION: OCR Relative Density/Contrast Primary Purpose: Investigate low and uneven contrast materials Test-Set Characterization: Low contrast pages Pages with low contrast zones Printing, Filming, & Age/Storage Defects Additional Products: Best practices Accuracy : Cost – Matrix Don’t forget to buy the Life Insurance

17 2002 September -- ejk/UF DISTILLATION: OCR Text Curvature and Other Defects Primary Purpose: Benchmark current capability to distill curved text & other defects of printing or filming Test-Set Characterization: Curved text zones Broken character zones Broken line zones Garbage elements (stains, etc.) Additional Products: (Additional automatic image correction processes)
