Abstract: A similarity calculating method and apparatus are disclosed. A similarity calculating method according to an exemplary embodiment of the present invention includes extracting similarity calculating data, which is determined in advance, by receiving a communication activity record for every user; modeling a communication activity pattern for every user and common information between the users based on the extracted similarity calculating data; and calculating a similarity between users using the modeled communication activity pattern for every user and common information. The modeling includes: modeling the communication activity pattern by calculating a value of a static feature from the similarity calculating data, and modeling the common information by calculating a value of a dynamic feature from the similarity calculating data.
