‘Delving’ Into The ‘Realm’ Of AI Word Choice

Several years ago, some eagle-eyed readers of scientific papers noticed an unusual trend—an increase in the number of abstracts using certain words. The terms, including “delve,” “realm,” “evolving landscape,” and more, were suddenly appearing more often than they used to.

Researchers analyzed the abstracts and compared them to abstracts written just a few years earlier, before the widespread availability of artificial intelligence large language model chatbots. They came to the conclusion that abstracts written by AI were more likely to use words from a list of around 20 favorites than regular human speech. The question was, why? If the models were trained on conventional writing, how did a preference for words such as “delve” creep in?

Host Flora Lichtman talks with Dr. Tom Juzek and Dr. Zina Ward of Florida State University, who set out to try to understand the origins of some of AI’s favorite words.
