Illustrata: Technology


Illustrata: Technology offers deep indexing for tables, figures, graphs, charts and other illustrations from the scholarly research and technical literature.

“Deep indexing” categorizes data, variables and other content represented in tables, maps, photographs and other figures. Usually, indexing of research articles is done at a rather high, general level where only the key concepts of the work are represented by a dozen or so index terms. But by going deeper and specifically indexing the content associated with all the individual tables and figures, Illustrata enables the researcher to find information that otherwise would not be retrievable in traditional, article-level and full-text indexing systems.

Search results -- the objects -- can be viewed along with the caption, author, and source information and additional index terms that can be used for further searching. A link is provided to the full-text documents when available, and a link back to the parent record provides a summary view of all the objects associated with that article. In most instances, the article abstract is displayed. The visualization of data and the interdisciplinary nature of Illustrata: Technology can also lead to unexpected discoveries or connections between seemingly disparate findings.

This was borne out by empirical evidence during the development of Illustrata when researchers were given access to a prototype and asked to comment on what they perceived as the potential uses and benefits of the system; such uses included:

  • Gaining faster and more precise understanding of the work reported in articles by direct examination of the tables and figures
  • Improving the efficiency of searching by providing more precise and smaller results sets
  • Locating and retrieving data in particular formats or particular object types
  • Making comparisons between their work and the work of others
  • Assisting with writing of review papers, meta-analyses, proposals, and for generating hypotheses
  • Supporting the transformation of practice and supporting the learning of new skills and methods, including how to effectively present results in tables, figures and graphs
  • Use of objects by librarians to directly answer reference questions

Browsable Indexes
A browsable index is an alphabetical listing of terms used in a specific field of a database. You can browse this list to see, for example, how authors' names are spelled and therefore how they are indexed, or what categories are used to classify each object in CSA Illustrata. Browsable Indexes are available for the following fields:
    Journal Name
    Object Descriptors
This last index, the Objects Descriptors Index, may be particularly useful because it is an alphabetical list of all the terms from each of the more specific fields:
    Object Geographic Terms, Q7=
    Object Statistical Terms, Q8=
    Object Subject Terms, Q5=
    Object Taxonomic Terms, Q6=
To access these browsable indexes, first click the purple Search Tools tab above the search form or the results display, then click the Indexes tab.
