AGU Abstract Archive Use Case
“To improve abstract discovery for the American Geophysical Union (AGU) meeting
archives by reducing uncertainty in the underlying data model and user interface.”

Library Science Principles in AGU Abstract Archive
![Page 5: Improving Information Discovery for the AGU Abstract Archive Brendan Ashby, Sherry Chen, Aris Peng, Eric Rozell, Akeem Shirley Xinformatics Spring 2012](https://reader036.vdocuments.us/reader036/viewer/2022062315/5697bf7b1a28abf838c83c73/html5/thumbnails/5.jpg)
Digital World
In the digital world, there are collections and directories.
• How is the content managed?
• How is it displayed?
Meaning through:• Signs, symbols, and how they
communicate• Spatial relations and their
similarity of appearance• Cause and effect
![Page 6: Improving Information Discovery for the AGU Abstract Archive Brendan Ashby, Sherry Chen, Aris Peng, Eric Rozell, Akeem Shirley Xinformatics Spring 2012](https://reader036.vdocuments.us/reader036/viewer/2022062315/5697bf7b1a28abf838c83c73/html5/thumbnails/6.jpg)
The Digital Library
• Access: The abstracts of all the papers residing in the archive are publicly available.
• Rights: All papers are attributed to who submitted them and where and when they were submitted.
• Legal: Restrictions are in place to limit submissions to relevant topics of study.
• Publishing: Only members, or persons referred by existing members are allowed to submit papers to the AGU archive.
![Page 7: Improving Information Discovery for the AGU Abstract Archive Brendan Ashby, Sherry Chen, Aris Peng, Eric Rozell, Akeem Shirley Xinformatics Spring 2012](https://reader036.vdocuments.us/reader036/viewer/2022062315/5697bf7b1a28abf838c83c73/html5/thumbnails/7.jpg)
Discovery
• Efficient: Users want the cause and effect relationship of their inputs to the outputs that the interface gives to become immediately apparent.
• No lag!• Ease: Simplify complex searches• Usability: Serve a wide audience via Java and Tomcat.• Intuition: Intuition is when users gain “understanding without apparent
effort”. o We utilize a “layer cake” methodology to how the different search
criteria are stacked on top of each other to the left of the screen. o We designed the queries to allow the user to narrow their search by
year or topic, but only as much as the user felt comfortable doing.

Blur the Lines
Can a non-expert just as easily use the system as an “expert” in the field?

Information Uncertainty of AGU Abstract Archive
![Page 10: Improving Information Discovery for the AGU Abstract Archive Brendan Ashby, Sherry Chen, Aris Peng, Eric Rozell, Akeem Shirley Xinformatics Spring 2012](https://reader036.vdocuments.us/reader036/viewer/2022062315/5697bf7b1a28abf838c83c73/html5/thumbnails/10.jpg)
Information uncertainty
• Uncertainty of information architecture• Uncertainty of information content• Uncertainty of information context
![Page 11: Improving Information Discovery for the AGU Abstract Archive Brendan Ashby, Sherry Chen, Aris Peng, Eric Rozell, Akeem Shirley Xinformatics Spring 2012](https://reader036.vdocuments.us/reader036/viewer/2022062315/5697bf7b1a28abf838c83c73/html5/thumbnails/11.jpg)
Not working for abstract!

Uncertainty of information context
1. Have to specify the year before search
![Page 16: Improving Information Discovery for the AGU Abstract Archive Brendan Ashby, Sherry Chen, Aris Peng, Eric Rozell, Akeem Shirley Xinformatics Spring 2012](https://reader036.vdocuments.us/reader036/viewer/2022062315/5697bf7b1a28abf838c83c73/html5/thumbnails/16.jpg)
