Abstract: To provide a hierarchical visual paradigm while maintaining the communication advantages of sibling extensions, a visual hierarchy simulation extension generates and maintains placeholders in a visually hierarchical manner, with the visual positioning of such placeholders informing the visual positioning of overlays of frames hosting the visual output of sibling extensions. Such a visual hierarchy simulation extension is utilized to layout and establish a desired visual hierarchy. One or more modules of computer-executable instructions are invoked to provide the relevant functionality, including the obtaining of the visual positioning of placeholders, the relevant visual translation between the visual positioning of placeholders and the visual overlaying of corresponding frames, the generation and movement of the corresponding frames, and the instantiation of extension content within the corresponding frames. The visual hierarchy simulation extension is hosted independently from the one or more modules.

Abstract: In the present disclosure, artificial intelligence (AI) processing is trained and leveraged to learn user-specific insights that are contextually relevant to a state of a user communication. Contextual information about a state of a user communication may be collected and analyzed. That contextual information may be cross-referenced with an extensive knowledge graph that is constructed from user context data. Exemplary AI processing may further be trained to apply a relevance analysis to assist with processing described herein including generation and curation of data insights that are most relevant to a state of a user communication. In some examples, the data insight generation process may be augmented by pre-generating data insights that may be relevant to a user communication prior to occurrence of the user communication. Further technical examples pertain to the rendering and presentation of representations of data insights through a graphical user interface (GUI).
