This disclose relates to computer-implemented management of an electronic slide deck, the electronic slide deck containing a set of slides to be presented individually. The computer system processes the slides of the electronic slide deck to autonomously group the slides into a plurality of groups, the autonomous grouping being performed by identifying the slides in each of the groups as having related content, generates in association with the electronic slide deck, grouping data in electronic storage accessible to the computer system, the grouping data denoting the identified groups of slides, and controls a user interface based on the stored grouping data to convey, to a user, information relating to at least one of the identified groups of slides.
