The U.S. State Department’s Office of the Historian has embarked on an ambitious effort to migrate its diplomatic history document archive from paper to an enriched electronic media for online consumption. We have extremely high standards for semantic precision and accuracy, due to Congressional mandates, which makes this unique resource useful to a broad audience, which includes scholars, government officials, and the general public. Furthermore, the new format allows us to repurpose our content and integrate it with “mashup” applications such as timelines and geographical map views.

 
This case study reviews the U.S. State Department’s requirements and the decision process that led us to adopt high-precision semantic markup standards that are supported by our tools as well as by our vendors. We will review our requirements and decision-making, and will show concrete examples of how the precise identifiers for people, locations, and events allow us to enrich the display of our documents online.
We will also review the full document lifecycle and the need for automated but high quality entity extraction tools to minimize document conversion costs. This case study will discuss some of the tradeoffs others may face when advanced technology decisions have both risks and rewards for the digital historian.
In this presentation we will:
 

• Review business requirements for a high precision entity extraction application
• Describe our semantic approach
• Demonstrate entity extraction
• Demonstrate timeline and other mashups
• Summarize project benefits
