UGASP: User and Group Aware Shopping Planner

We present a prototype system for planning shopping-related trips in the settings in which an individual may need to purchase a collection of items for which the requests originate from different categories of groups. Specifically, we consider scenarios in which the user is affiliated with a family and other (multiple) social circles - with varying temporal duration (e.g., from a specific party/event, to longer lasting preference-based memberships such as chess playing, reading club, etc.). Each of the groups may have its separate list of items to be purchased at a given time - e.g., grocery for the family; wine and cheese for a social event - however: (1) a particular individual may be a member of multiple (different) groups; (2) a particular group may have different shopping list (for different purposes); and (3) a user may be at different location at times when different requests originate. Our UGASP (User and Group Aware Shopping Planner) system aims at: (1) Generating trajectories for individuals to complete part of the purchase list, based on their group memberships; (2) Calculating new trajectories, based on updates of the purchase assignments to different users.
