1. A method comprising: retrieving, by a computer processor of a computing system, event data comprising time stamped artifacts generated during activities performed by a user; extracting, by said computer processor from said event data, attributes associated with said activities performed by said user; segmenting, by said computer processor based on said attributes, said event data into logical groups of related activities associated with said activities performed by said user; identifying, by said computer processor, key information associated with each logical group of said logical groups of related activities with respect to said activities performed by said user; identifying, by said computer processor from said key information, logical group attributes associated with each said logical group; evaluating, by said computer processor executing a sentiment analysis with respect to said event data and communications of said user, said user; ranking, by said computer processor based on results of said evaluating, said logical groups of related activities, wherein said ranking comprises: performing a ranking process with respect to said logical groups of related activities in terms of relevance in response to a specified prompt from an application being completed, wherein said specified prompt is a selected from the group consisting of a request to describe a logical group with a high customer satisfaction, a request to describe a leader role, and a request to describe a work function using a specified scripting language; and matching user activities of said user with information specified in a template via executing similarity judgment algorithms, wherein similarity judgment algorithms comprise algorithms selected from the group consisting of an evidence of topical matching algorithm using semantic and entity analytics against an agenda/description of a specified event, an information algorithm associated with attendees of said specified retrieved from personal profiles of social media repositories associated with said user, and an attachment algorithm associated with attachments including a presentation slide deck attached to a calendar entry associated with the specified event or multi-media files associated with said specified event; presenting, by said computer processor to said user said logical groups of related activities according to results of said ranking; and generating, by said computer processor based on said ranking, an engagement summary associated with said user and said logical groups of related activities.
