Abstract

The course finalizes the customer analytics track by teaching students essential skills that are especially useful for the analysis of various social networks (e.g. networks of social media users, buyers, etc.): automated data collection from various sources (including the Web), analysis of network data and text mining. The course has two parts: in the online part students will be given access to 4 courses at the DataCamp platform which will serve as lectures and practical tutorials on how to collect and manipulate data from various sources with a special emphasis on scraping web data and using APIs. Academic support for the course is provided via LMS, where students can find guidelines and recommendations for self-study and sample questions for exam preparation. The exam is also conducted using LMS testing functionality. DataCamp platform is used in this course so that students can improve their R coding skills. DataCamp is an interactive learning platform for R, Python & SQL for Data Science. They teach cutting edge data analysis tools in an easily accessible manner.  For every topic an introductory tutorial-style lecture is given to familiarize students with the topic  A set of case studies every week is solved in class  90% of time is allocated to practicing R programming skills

Learning Objectives

• Scrape data from most websites
• Use APIs to obtain data from websites
• Present networked data in a format appropriate for quantitative analysis
• Develop and apply new research methods by combining and modifying existing techniques
• Solve CRM analytics problems using special methods for analyzing network data and machine learning techniques

Expected Learning Outcomes

• Importing data from various sources
• Building simple Shiny web applications for customer analytics
• Presenting networked data in a format appropriate for quantitative analysis
• Processing texts using basic string manipulations, as well as sentiment analysis and topic modeling
• Scraping data from most websites
• Solving CRM analytics problems using special methods for analyzing network data and machine learning techniques
• Using APIs to obtain data from websites

Course Contents

• Advanced aspects of importing data to R
• Working with Web data in R
• Building Web Applications in R with Shiny
• Network Analysis in R
• Predictive Modeling with networked data
• Text Mining
• Sentiment Analysis
• String Manipulations in R
• Topic Modeling

Assessment Elements

• Kahoot (tests)
  Weekly tests using Kahoot.it platform covering the material studied in previous weeks. To compute Grade_Kahoot the sum of Kahoot points is calculated for each student. Then it is converted to a percentile from 0 to 100 using the corresponding Excel formula. An alternative % of max is calculated as the % of maximum score achieved by the top-performer. Grade_Kahoot=max(percentile, % of max)
• Midterm asessment
  Each student should take a few Data Camp courses specified by the instructor (up to 4 courses). Free access will be granted to students of this course. The grading is based NOT on the DataCamp’s score, but on the student’s performance on the test given by the instructor. The test will check how well students mastered the material studied both in class and at DataCamp. Grade_Midterm is the score from 0% to 100% displayed by the LMS.
• Empirical case studies solved in class
  75-min. tests given at classroom every week. Each problem set consists of 2-5 problems. The total number of case studies equal the number of tutorials (around 10-12 case studies). For each case study a student can get the following scores:  0 (absent or everything is incorrect)  1 (present, but mostly incorrect solution)  2 (some mistakes)  3 (no mistakes) Grade_Cases is computed as the % of a student’s total score out of the maximum achievable score.
