KCRS: KClustering Recommender System for Component Configuration

In recent years, the exponential growth in the number of items and products handled by e-commerce sites has led to the introduction of intelligent systems aimed at supporting users during the decision-making proces. Making the choice of a product among thousands of items becomes complicated for consumers, and in response to this problem, recommender systems (RS) are born. These systems are a set of algorithms based on the concept of information filtering and make it possible to reduce the cognitive effort required of users. In this paper we present a model-based RS, belonging to the collaborative filtering (CF) category, for the e-commerce website of the company Nathan Instruments (NI). Thus, the main objective of this paper is to provide an intelligent approach for recommending configurations of hardware components for Computers. This configurator uses clustering algorithms to address the problems associated with small dataset sizes. Finally, in the experimentation and conclusion sections it is reported how the proposed model simplifies the decision process related to the required computer customization in terms of hardware and software components.
