Overview of this book

Data mining is the first step to understanding data and making sense of heaps of data. Properly mined data forms the basis of all data analysis and computing performed on it. This learning path will take you from the very basics of data mining to advanced data mining techniques, and will end up with a specialized branch of data mining—social media mining. You will learn how to manipulate data with R using code snippets and how to mine frequent patterns, association, and correlation while working with R programs. You will discover how to write code for various predication models, stream data, and time-series data. You will also be introduced to solutions written in R based on R Hadoop projects. Now that you are comfortable with data mining with R, you will move on to implementing your knowledge with the help of end-to-end data mining projects. You will learn how to apply different mining concepts to various statistical and data applications in a wide range of fields. At this stage, you will be able to complete complex data mining cases and handle any issues you might encounter during projects. After this, you will gain hands-on experience of generating insights from social media data. You will get detailed instructions on how to obtain, process, and analyze a variety of socially-generated data while providing a theoretical background to accurately interpret your findings. You will be shown R code and examples of data that can be used as a springboard as you get the chance to undertake your own analyses of business, social, or political data.

Chapter 7. Building a Retail Recommendation Engine

In this age of Internet, everything available over the Internet is not useful for everyone. Different companies and entities use different approaches to find out relevant content for their audiences. People started building algorithms to construct a relevance score, based on which recommendations could be built and suggested to the users. In my day to day life, every time I see an image on Google, 3-4 other images are recommended to me by Google, every time I look for some videos on YouTube, 10 more videos are recommended to me, every time I visit Amazon to buy some products, 5-6 products are recommended to me, and, every time I read one blog or article, a few more articles and blogs are recommended to me. This is an evidence of algorithmic forces at play to recommend certain things based on user's preferences or choices, since the user's time is precious and content available over Internet is unlimited. Hence, recommendation...
