The United States Patent and Trademark Office awarded a patent to ProQuest's Deep Indexing, granting the company patent protection on the CSA Illustrata technology. ProQuest extracts and indexes data about graphic objects in journal literature to allow it to be searched as if it were full text. Deep indexing was pioneered in CSA Illustrata, and is now available in the new ProQuest platform.
ProQuest's Deep Indexing creates metadata from the elements within illustrations so that graphics, including tables, charts, photos, and drawings, can be searched for their contained content. The feature is deployable across ProQuest data, including its new primary platform, which was rebuilt based on surveys from more than 6,000 end users.
