METHOD OF INCREASING INFORMATION PERTINENCE FOR E-COMMERCE RECOMMENDER SYSTEMS BASED ON IMPLICIT DATA
- S. A. Philippov

The paper describes the method of increasing pertinence of information in e-commerce recommender systems based on implicit data, i.e., due to the processing of user activity associated with the decision-making process. The method works successfully in situations where information about user activity is absent or little informative. Practical application of this method in e-commerce systems can improve their efficiency through targeted supply of goods and services to consumers. The main feature of the proposed method is the combined use of Item-Item CF (collaborative filtering) and User-User CF methods taking into account the implicit data collected. The features of the proposed method are verified by a prototype software that is installed on the existing online store Thaisoap.
