CSA Illustrata: Natural Sciences Providing Leadership in Deep Indexing Dan Dyer CSA
Todays discussion DEEP INDEXING: a new approach to indexing the scholarly literature How response from researchers shaped CSA Illustrata: Natural Sciences How CSA Illustrata enhances existing library services and changes the way users approach research questions
Why index Tables and Figures? They contain important and valuable information –Figures and tables represent the distilled essence of research – the closest thing to raw datasets Researchers want access to data They are invisible
Reasons why data is hidden in traditional searches 1.Data variables do not appear in any index. –there are no indexing hooks in title, abstract or caption for dissolved oxygen, below. 2.A search of the full text bypasses the image files –text in tables & figures is considered an image, not searchable text Table 1. Depth, physico-chemical and sedimentological variables.
Reasons why data is hidden in traditional searches 3. Data can be hidden within a large result set –A search for wind stress and Pacific produces: a) >1,900 generally valuable results or…. b) or a highly targeted subset vs.
Reasons why data is hidden in traditional searches 4. False Hits – an article may mention wind stress and Pacific in a general way, but may not actually contain the data of interest
Deep Indexing of data summaries would make them visible and retrievable Deep Indexing involves: –Identification of tables and figures (images, charts, maps, etc.) found within a scholarly article –Extraction and indexing of data surrounding the table or figure to provide indexing for each image
Deep Indexing provides An image of the Figure or Table Full caption Article citation with link to full abstract Category (Graph, Satellite Image, …) Subject, taxonomic, geographic and statistical descriptor terms taken from caption, data variable labels and surrounding text Units for subject variables Link to Full Text
Deep Indexing – Abstract Record Abstract Record enhanced with: Objects thumbnails Captions Index terms Link to Object DB Other metadata
Abstract Record Thumbnails of all tables and figures displayed Click on Figure for Object Record
Deep Indexing Object Record Objects Record includes: Full image Captions Index terms Link to full text Other metadata
FULL OBJECT RECORD Publisher attribution Object Descriptors
Preliminary Market Research Indicated a Need for: Researchers to find New relevant information Save time Enhanced cross-disciplinary research
What Researchers Currently Do Search for photographs and maps more than tables, figures or graphs Use Google most often Level of satisfaction with traditional searches consistently rated low –locating objects is difficult –in general, academic figures, tables, and graphs are not available to search
In depth market research: final report available at info.csa.com/csaillustrata Carol Tenopir and Robert Sandusky University of Tennessee web.utk.edu/~tenopir/ Enhanced Searching through Deep Indexing: Scientists Reaction
" Overwhelmingly, respondents said the ability to search for specific types of objects would make a difference in their search and discovery processes…... save time... work more efficiently... aid in presentations... find more relevant results." Tenopir, C., & Sandusky, R.J. (2006). The Value of CSA Deep Indexing for Researchers - Draft Final Report Researcher Response …
They also told us… Quality of the tables was PARAMOUNT. Linking to the full text was crucial since they would not use an image unless they were sure of the context. They wanted to see a list of articles as well as a list of relevant objects As a result of their responses, many changes were made to CSA Illustrata.
Searching CSA Illustrata You can enter the database through the traditional abstracts search interface, or directly When using the traditional abstracts interface, the search results will be flagged to indicate objects are available Advanced searches in both options will allow you to search within figure captions, article vs. object descriptors, and so on.
Traditional Abstracts Search Results will include pinkies
Results from a direct search of objects includes thumbnails
Both search paths will lead to enhanced abstract records containing thumbnails of all objects in the article…

Researchers identified many potential uses To find relevant articles researchers would not otherwise find To retrieve and use images To compare their work with others To support meta-analysis Prepare teaching/lecture/presentation materials
Potential Use: To find articles they would otherwise miss Sometimes tables, figures, maps, etc. are hidden in other papers. This search tool gives me the opportunity to find these items too …possibility to find information that might be unnoticed in a traditional database …ability to find data that may not be reflected in the title and abstract of the article
Potential use: Prepare teaching/ lecture/presentation materials Incorporating tables and figures directly into presentation software Useful to show students the main point of a paper Show students what microorganisms look like Guidance in Table/Figure design
CSA Illustrata in summary Provides through Deep Indexing an innovative approach to locating information in the scholarly literature Multidisciplinary content International in scope Can be searched alone or combined with other CSA databases Intuitive interface designed with researcher input
In Summary: Benefit to Libraries The first innovation in indexing in over 40 years Brings additional value to expensive electronic collections to which the library has subscribed Additional information content unique to CSA Illustrata Users are lead directly to the specific and relevant parts within the text of an article. Useful for answering reference questions Intuitive interface makes user education easy
In Summary: Benefits to Researchers Find research material that would have been lost in general article indexing or searching all the full text Save time because they can target searches to locate the information most relevant to their work Browse categories of objects (e.g. all graphs containing a particular variable; all tables listing a specific element; etc.) Make visual presentations for conference presentations or teaching purposes easy
