2. Book pages annotated by underlines & marginal notes, etc.

3. Linked annotations: relationship of annotations

A line linking the region and the note

4. Annotations for historical documents
My text analysis of the diary of 19-20th century German
Mathematician David Hilbert, who is said the father of 20th century mathematics.

5. What are we doing?
Annotating images of book pages and historical documents by
adding markups, bookmarks and texts (e.g. marginal notes)
relating them each other by links
and, further relating them to resources outside: books, papers & Web resources, e.g. references to papers , books and documents in archives.

6. For the cases of Web and PDF documents…
Cyber documents, e.g. PDF files and HTML files, can be digitally annotated in similar ways.
Furthermore, words in such digital documents are searchable.
Imagine that historical documents can be digitally annotated and are searchable. Examples of such documents:
handwriting documents, e.g. Hilbert’s diary.
Image-base digital archives of books, journals and other documents, now widely available on Web thanks to some libraries…

7. An example of image-base digital archives
国立国会図書館近代デジタルライブラリー　(National Diet Library, Digital library from the Meiji Era)
143,000 books from Meiji and Taisyo eras are open to the public.

8. The goal of SMART-GS project
Providing platforms for marking up, linking and searching historical documents on PC and on the network.
Looks as a dream?
No, it’s not a dream!
We have already built a JAVA application SMART-GS with the full functions required except the network features.

9. Demo of SMART-GS applied to David Hilbert’s diary

Searching a word in the diary
The word searched is “Kronecker” another German mathematician’s family name.

10. Working with SMART-GS on three wide monitors

11. Towards tools on the Net
Historians with similar interests are often scattered through the globe. They wish to share knowledge for every-day researches, but it is not so easy.
SMART-GS technology will provide an excellent help for world-wide collaborations of a team of historians.
It may also provide a dramatic improvement on image-base online digital archives of handwritten and/or printed historical documents.
The key of such network version is the way the annotation was attached to images of historical documents: Gs-file!

12. Gs-file: an XML file storing annotations and others
Annotations are converted into the XML-format and stored in gs-file = +

historian
Historian publish their own gs-files to annotate document images in a public archive.
They can annotate also gs-files of other historians.
Gs-file
reader
A reader can browse views of historians, if a historian makes his view open to the public.

16. Future network version can markup digital archives

17. Another model of a network version -online collaboration model-
Historian publish their own document images and gs-files (views). They comment to views of other researchers.

18. Conclusion
SMART-GS system has been already applied to a study of a very important diary in the history of mathematics and proved its usefulness.
There is also a plan to use SMART-GS in a project to transcribe a gigantic diary of Yuuzaburo Kuratomi ( ), a chairman of the privy council.
The network versions in the future will be useful for research collaborations and using digital archives.

19. Conclusion (continued)
For technical and financial reasons, historians must often use secondary sources rather than primary sources. However, the secondary sources are products of “interpretations” of their authors!
SMART-GS technology together with online digital archives will provide historians with an easy and reasonable way to use primary sources for their studies.
