Abstract: An information cataloging system disclosed herein provides a system and method for inferring relationships between various elements, such as e-mail address, phone number, etc., of various observations, such as business cards, observations obtained from the Internet, etc. The method comprises representing various elements, such as name, e-mail address, etc., using nodes, representing the relations between the various elements using edges connecting these nodes, computing a distance between two disparate nodes, wherein each of the two disparate nodes represent an element related to the entity. An implementation of the information cataloging system disclosed herein also provides a method of calculating noise and signal to noise ratio attached to various nodes and using such noise information in calculating confidence level of relationships between various elements.
