Satyanarayana this issue. Online companies generally collect customer Abstract: In this emerging global economy, e-commerce is an reviews and use them to recommend products to other inevitable part of the business strategy. Moreover, the business companies at a lower cost. Such software systems that make world comprises the upcoming entrepreneurs who are unaware of customized responses are known as recommendation the current trends in marketing. Therefore, a recommendation systems. The recommendation systems are beneficial for system is very essential for them. In this paper, a fully automated both the user and the vendor. They save the time and money recommendation system for the upcoming entrepreneurs to become successful in their business is proposed. The system works of the users by helping them find out the best product and in three stages. In the first stage, the most transacted product is company within no time. However, the effectiveness and identified using association rule mining FP growth algorithm. reliability of such recommendation systems are to be studied This helps in extracting useful information from the previous properly. transacted data by mining the entire set of frequent patterns. The In this paper, a fully automated recommendation system is second stage identifies the most customer preferred company proposed. Here, association rule mining based on the FP based on review analysis. The multilevel clustering process with growth algorithm is used. The review data set thus collected the generalization of data review is implemented to achieve an is analyzed using a review analyzer system. The review accurate review of the product.

In the third review dataset is analyzed using a multilevel K-means stage, the reviews are sorted using a polarity shift sentiment algorithm and further classified into positive and negative classification algorithm. It helps in sort positive and negative reviews using an ensemble classifier. The best product is reviews thereby rating a company. The top rated company would recommended using a product recommendation system based give the best product. Thus, the best product can be identified. on the rating of a company based on the reviews.

Recommender systems assist consumers in making product choices by providing recommendations of the range of products and services offered in an online purchase environment. The quantitative research study investigates the influence of psychographic and sociodemographic determinants on the interest of consumers in personalized online book recommendations. The author presents new findings regarding the interest in recommendations, importance of product reviews for the decision process, motives for submitting ratings as well as comments, and the delivery of recommendations. The results show that opinion seeking, opinion leading, domain specific innovativeness, online shopping experience, and age are important factors in respect of the interest in personalized recommendations. Nicolas Knotzer studied business administration with the focus on information systems, management control and project management. From 2001 to 2006 he joined the Institute for Management Information Systems at the Vienna University of Economics and Business Administration. The author received his doctoral

  • 10 Interacting with Recommenders—Overview and Research Directions
    10 Interacting with Recommenders—Overview and Research Directions MICHAEL JUGOVAC and DIETMAR JANNACH, TU Dortmund Automated recommendations have become a ubiquitous part of today’s online user experience. These systems point us to additional items to purchase in online shops, they make suggestions to us on movies to watch, or recommend us people to connect with on social websites. In many of today’s applications, however, the only way for users to interact with the system is to inspect the recommended items. Often, no mechanisms are im- plemented for users to give the system feedback on the recommendations or to explicitly specify preferences, which can limit the potential overall value of the system for its users. Academic research in recommender systems is largely focused on algorithmic approaches for item selection and ranking. Nonetheless, over the years a variety of proposals were made on how to design more interactive recommenders. This work provides a comprehensive overview on the existing literature on user interaction aspects in recommender systems. We cover existing approaches for preference elicitation and result presen- tation, as well as proposals that consider recommendation as an interactive process. Throughout the work, we furthermore discuss examples of real-world systems and outline possible directions for future works.
