In science, images visualize data or are data…

Text, data, and images together convey scientific meaning

Reading patterns may vary with purpose …
Sometimes you need an entire article or most of one (catching up or writing)
Sometimes you need just a part like a paragraph or picture (teaching or to check a fact)
Sometimes you need citations or data beyond the article (research)

What scientists currently do

to “be inspired by how other researchers set up figures and tables”
Potential uses: finding, comparing, learning
“Sometimes tables, figures, maps, etc. are ‘hidden’ in other papers.”
“comparing data from other researchers to your own findings.”

Potential Use: To retrieve and use images for Research and Teaching

Potential Use: To compare their work with others’
![Page 21: Text+Images+Data: A More Complex Way to Convey Results of Scientific Research](https://reader036.vdocuments.mx/reader036/viewer/2022081603/5591f8b01a28ab0c4f8b45da/html5/thumbnails/21.jpg)
Potential Use: To support analysis
Participants anticipate using the objects retrieved : for review articles to “be inspired by how other researchers
set up figures/tables” to “expose me to different areas in
which similar methods are used”

Potential to change practice
“I discovered some new
publications in areas where
I thought I knew all.”
“…made me think about different ways that data is conveyed…I’ll design my own future graphs and figures to better ‘stand alone’ as a result.”
“I actually did a few
successful searches
where unexpected and
interesting information
came up.”

Suggestions for Success
Images must be of high quality with ability to enlarge thumbnail images
The context of the whole article is very important—in fact it may be dangerous to see images without the context
Allow table contents to be searchable and support extraction of data from tables

Others can access my data easily
Place all of my data into a central data repository
I share my data
Place at least some of my data into a central data repository

I would use other researchers' datasets if easily accessible
Lack of access to data has restricted my ability to answer scientific questions
Lack of access to data is a major impediment to the progress of science

In conclusion… Providing access to visual material can help
scientists in many ways Sometimes scientists need just a part of an
article and systems that help them find parts Sometimes they need to read an entire article Sometimes they need data (and many are
willing to share) Think at many levels of granularity—journal
issues AND whole articles AND parts of articles AND extensions to articles such as data
