System and method for recommending repeat-purchase products using modified self-similarity

A method for recommending repeat-purchase products using modified self-similarity, the method being performed by a computer in an environment in which user equipment (UE), a database, and a web server are connected over a network, the method comprising:

• step S100 of receiving, by a user information reception unit, user information from the database when the UE connects with the web server;
• step S200 of calculating, by a modified self-similarity calculation unit, a modified self-similarity (MSS) using the user information received by the user information reception unit;
• step S300 of calculating, by a similarity calculation unit, sums of similarities between products by substituting the modified self-similarity, calculated by the modified self-similarity calculation unit, into an inter-product similarity calculation matrix;
• and
• step S400 of aligning, by a product recommendation unit, the sums of similarities between products calculated by the similarity calculation unit, and transmitting, by the product recommendation unit, product information fulfilling preset criteria to the UE.
