"Method And System For Determining Similarity Of Objects Based On Heterogeneous Relationships"

Abstract: A method and system for measuring the similarity of objects based on relationships with objects of the same type and different types and similarities of those objects to other objects is provided. In one embodiment, the similarity system defines intra-type and similarity functions for each type of object. The similarity system may combine the intra-type and intra-type similarity functions for a certain type into an overall similarity function for that type. After defining the similarity function, the similarity system collects attribute values for the object, which may include relationship data between objects of the same type, referred to as intra-type relationship, and relationships between objects of different types, referred to as intra-type relationships. After collecting the attribute values for the objects, the similarity system solves the intra-type and intra-type similarity function by iteratively calculating the similarities for the objects until the similarity converge on a solution.
