Recommendation Systems for big data

Prof. Samee U. Khan & Mr. Muhammad Usman Shahid Khan
North Dakota State University, USA

Date: July 23, 2014 - 5:45pm
Location: Ballroom 3


    Recommender systems are special information filtering systems that predict the users’ preference in the near future. Recommendation systems have been developed since the 90s and apply numerous knowledge discovery techniques on users’ historical and contextual data to suggest information, products, and services that best match the user’s preferences. With the advancement in communication infrastructure and easy access of e-commerce and mobile social network applications, such as Amazon, Facebook, Twitter, and Foursquare have resulted in tremendous growth in the volume of the data. According to International Data Corporation the data consumed only in the USA is expected to be doubled in every three years from 2012 to 2020. Moreover, the MIT Slogan Review has presented the result of the survey that the top firms are investing five to six percent more on their data to extract valuable information than the lower performers. The competition in the industry and the huge volume of the data demand newer and better solutions for the recommender systems to address the challenges that are being caused by the big data. In this tutorial, we will consider the future research directions in the recommender systems and the challenges caused by the big data on recommender system, foremost among them are

    • Scalability
    • Data sparseness
    • Cold start
    • Long Tail


    This tutorial will enable you to understand

    • What are recommender systems and how they predict personalized and group recommendations?
    • Why new recommender systems are mandatory to respond big data demands?
    • What are the open challenges for recommender systems in a big data era?
    • What are the future research directions in recommender systems?
