A method and system for ranking objects of different object types based on their popularity is provided. A ranking system calculates the popularity of objects based on relationships between the objects. A relationship indicates how one object is related to another object. Thus, objects of one object type may have one or more relationships with objects of another object type. One goal of the ranking system is to rank the objects of the different object types based on their popularity. The objects and their relationships can be represented using a graph with nodes representing objects and links representing relationships between objects. The ranking system assigns a popularity propagation factor to each relationship to represent its contribution to the popularity of objects of that type.
