Systems and methods are provided for measuring the level of relative activity (relationship) between two entities (e.g., people, companies, organizations, etc.) in a group as compared with others in that group or in a subset of that group. A group or subset of a group can be defined manually or automatically by the program. Once the activity is measured, it is further analyzed to generate behavioral attributes (e.g., trust, respect, mutually enjoyable company or personal relationship, reciprocity and shared experience) of the relationship. These attributes may be employed to derive characteristics such as the strength of the relationship for each pair of entities. The relationships and characteristic and/or attributes may then be displayed in a simple to understand manner.
