The personalized product preference and decision-making recommendation systems are highly demanded to handle big data and to increase service quality of the e-commerce platforms in the competitive industries. Previous recommender systems were hard coded and only extracted items from the same category. With this tactic, customers are limited to viewing only one category of products; items with several categories cannot be viewed. A concern for the e-commerce sector, particularly in the healthcare and pharmaceutical industries, is the growth of consumer preferences, the issue of cold starts, and the huge number of stocks holding units for new items. Therefore, this study aims to develop a product recommendation system for an e-commerce platform which deals with health supplements. For this reason, collaborative and content-based filtering are combined to propose a hybrid recommender system. In the proposed hybrid model, user’s actions are converted into implicit rating weightage first. Then, to tackle the problem of increasing customer preferences, collaborative filtering is used to generate user’s rating for warm-start items. Moreover, content-based filtering is used to solve cold start problem by recommending products to the users based on the similarity of the products regardless of user profile. Term frequency- inverse document frequency (TF-IDF) algorithm is adopted to weight the feature from the dataset first, then it creates step-by-step cosine similarity table. Finally, the proposed hybrid model is evaluated based on error metrices, ranking metrices, and business metrics and then compared based on the standard benchmarking algorithms. The best algorithm is selected to be used for the system development. Finally, the proposed hybrid model is developed and integrated into the real online e-commerce platform for healthcare company to handle the large number of stocks keeping units, cold start issues, and increasing customer preferences. This study can assist the healthcare companies to recommend relevant products to their customers and to help them stay competitive in healthcare e-commerce industry.
