Abstract

Recommender Systems help consumers navigating through large product miscellany, making decisions in e-commerce environments and overcome information overload. These systems take the behaviour, opinions and tastes of a large group of consumers into account and thus constitutes a social or collaborative recommendation approach. In contrast, content-based technique depends on product features and textual item descriptions. Knowledge-based technique, finally, produce item recommendations based on explicit knowledge models from the domain. Demographic technique purpose to categorize the consumer based on personal aspect and make recommendations based on demographic classes. Hybrid approach combines two or more techniques. Marginal utility is economic idea because economists and marketing research use it to discover how much of an item a consumer will purchase. Association rule mining technique concentrates on the mining of associations over sales data and help shop managers to analyze past transaction data and to improve their future business decisions and recommend products to a consumer on the basis of other consumers’ ratings for these products as well as the similarities between this consumer’s and other consumers’ tastes. This paper encapsulates subjective and objective parameter to design effective recommendation technique and also present model on cold start problem in e-commerce recommendation system.
