WEB-INTERFACE PERFORMANACE
Primary Purpose: Characterize the bias of individuals conducting study Products: How to use ActivePaperTM to Your Advantage Integration with CONTENTdm, XPAT 5.0, other Alternate deliverable images Centralized service – Distributed content – Variable platforms 2002 September -- ejk/UF
4
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 2002 September -- ejk/UF

DISTILLATION Document Zoning Optical Character Recognition
2002 September -- ejk/UF
11
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) 2002 September -- ejk/UF
12
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 2002 September -- ejk/UF
13
DISTILLATION: OCR Distillation Source Images 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 2002 September -- ejk/UF
14
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 2002 September -- ejk/UF
15
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 2002 September -- ejk/UF
16
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 2002 September -- ejk/UF
17
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) 2002 September -- ejk/UF
