Methods and systems for leveraging a topic divergence model to generate dynamic sidebar chat conversations are disclosed. A method includes: collecting, by a computing device, data from a first group chat; determining, by the computing device, a main topic of the first group chat and a current topic of the first group chat using the data collected from the first group chat; determining, by the computing device, a first divergence score representing a degree of divergence between the main topic of the first group chat and the current topic of the first group chat; determining, by the computing device, that the first divergence score exceeds a predetermined threshold; and in response to determining that the first divergence score exceeds the predetermined threshold, the computing device creating a second group chat; determining an efficacy based on an emotive analysis which increases as the divergence score decreases.

Controlling the volume of a Virtual Personal Assistant (VPA) by receiving radio frequency (RF) data associated with a user, identifying a location of a user relative to the VPA, creating a volume adjustment model using the data and VPA data, tracking movement of the user based on the data, and adjusting a volume of the VPA according to the volume adjustment model.

Methods, computer program products, and systems are presented. The method computer program products, and systems can include, for instance: obtaining image data representing page content of a physical book; running a character recognition process to process the image data for providing a text string of machine encoded text corresponding to text of the physical book; identifying within a data repository that stores one or more electronic book a string of text of an electronic book that matches the text string of machine encoded text; and based on the identifying, digitally bookmarking the electronic book.
