Artificial Intelligence (AI)

Information about AI: how to use, evaluate, and learn more

Recommended research tools

AI as a topic represents a highly diverse field of study that uses information from many different disciplines, not just computer science. Some fields that contribute to AI research include psychology, engineering, robotics, neurobiology, linguistics, and mathematics. As the list below indicates, this means that to do comprehensive research on AI, you will need to look at many disparate and seemingly unrelated databases.

However, just because it doesn’t say ARTIFICIAL INTELLIGENCE or MATHEMATICS or TECHNOLOGY doesn’t mean it can’t be relevant to what you are doing.  Do not neglect a source because it does not seem to fit your conception of what you want.


Ball State University Libraries provides access to authoritative and accurate sources of information on peer-reviewed and otherwise scholarly publications through the Articles & Databases page (Databases and interfaces (ie aggregators)).  Remember that part of your tuition goes to pay for such resources and services- you do have a subscription to journals like Nature through your status as a student at Ball State.

The Articles & Databases pages can be viewed in a couple of different ways.  You can look at an A-Z list of all the databases we offer access to or you can choose a subject (e.g. Science or Technology) and just look at databases relevant to your field of interest. 

For instance, go to the Articles & Databases page and click the Subject menu box. Then click on the Science menu item.  This will bring up only those databases concerned with the hard sciences including mathematics.  Another area that might be of use is Technology.

DOI (Digital Object Identifier)

Digital Object Identifiers (DOIs) are special strings of numbers and letters that form a persistent link to individual publications. They are issued at the time of publication, much like an ISBN or a serial number. DOIs can be attached to a number of different publications, including journal articles, books and book chapters, conference papers, reports, and so on. The DOI system provides a technical and social infrastructure for the registration and use of persistent interoperable identifiers, called DOIs, for use on digital networks.

You may have already seen a DOI and not realised what it was – all DOIs start with “10.” and are ‘built’ according to the publisher and journal involved – for example, the DOI for the 2004 article “Post-fire survival and reproduction of rehabilitated and unburnt koalas” from the Elsevier-published journal Biological Conservation is 10.1016/j.biocon.2004.03.029.

You can think of DOIs as social security numbers for individual electronic files (ie journal articles or images) which means that the article can be tracked and found by this number as though you had typed in the full citation. DOIs act as permanent links to individual papers, documents, articles, abstracts, photographs, models, etc.

Most indexing services (ie databases/aggregators) use the DOI standard now and some citation styles like APA are beginning to require it if available. Some will allow you to search by the DOI (eg Web of Science, SciFindern) but you can also use OneSearch, dx.doi.org, DataCite, and CrossRef to “resolve” the link (i.e. find/retrieve the object in fulltext or original format).

In the Ball State University Libraries system, you can use Citation Linker to find fulltext articles with nothing more than a DOI: just copy and paste the DOI into the DOI field on the Citation Linker page and click submit. Find It @ BALL STATE will then search our databases for a fulltext version of the article in question or connect you to our Interlibrary Loan service to obtain it from another institution.
