A computer-implemented method and system may modify categories for points of interest (POIs) for display on a map at a client computing device based on a bias value corresponding to a classification of a user. A system may receive interaction events from client computing devices. The interaction events may each include an indication of a user interaction with a POI displayed on a digital map at a client computing device and each POI may include a category and a default zoom level. Using a user's location data, the system and method may classify the user based on the user's familiarity with an area surrounding the interaction event POI and assign a numerical bias to POIs that include the category of each interaction event POI. Subsequent requests for mapping data may then return categories of POIs according to the type of user sending the request based on the bias value.
