Transcription

1 Course Syllabus BIA658 Social Network Analytics Fall, 2013 Instructor Yasuaki Sakamoto, Assistant Professor Office: Babbio 632 Office hours: By appointment Course Description This course introduces concepts and theories of social network and social media analyses. Application areas include customer profiling, community and trend detection, targeting, sentiment analysis, and development of recommendation systems. Course Objectives In this course, students will: master theories of social networks and social behavior - acquire techniques for analyzing social network data; apply analytical skills to social network data ; apply social network analysis to marketing research Course Outcomes After taking this course, students will be able to: statistically analyze social networks ; model the evolution of social networks ; describe network properties - predict network behavior ; help develop marketing strategies based on social network analysis Course Materials We will use articles as reading materials. These articles will be available online ( I recommend the following books: Wasserman, S., & Faust, K. (1994). Social network analysis: Methods and applications. Easley, D., & Kleinberg, J. (2010). Networks, crowds, and Markets; Reasoning about a highly connected world.

2 Grading Here is the breakdown for the grading purposes: - Participation 20% - Assignments 30% - Project 50% Ethical Conduct The following statement is printed in the Stevens Graduate Catalog and applies to all students taking Stevens courses, on and off campus. "Cheating during in-class tests or take-home examinations or homework is, of course, illegal and immoral. A Graduate Academic Evaluation Board exists to investigate academic improprieties, conduct hearings, and determine any necessary actions. The term 'academic impropriety' is meant to include, but is not limited to, cheating on homework, during in-class or take home examinations and plagiarism." Reference: The Graduate Student Handbook, Academic Year Stevens Institute of Technology, page 10. Consequences of academic impropriety are severe, ranging from receiving an "F" in a course, to a warning from the Dean of the Graduate School, which becomes a part of the permanent student record, to expulsion. Consistent with the above statements, all homework exercises, tests and exams that are designated as individual assignments MUST contain the following signed statement before they can be accepted for grading: I pledge on my honor that I have not given or received any unauthorized assistance on this assignment/examination. I further pledge that I have not copied any material from a book, article, the Internet or any other source except where I have expressly cited the source. Signature Date Please note that assignments in this class may be submitted to a web-based anti-plagiarism system, for an evaluation of their originality. Course/Teacher Evaluation Continuous improvement can only occur with feedback based on comprehensive

3 and appropriate surveys. Your feedback is an important contributor to decisions to modify course content/pedagogy which is why we strive for 100% class participation in the survey. All course teacher evaluations are conducted on-line. You will receive an one week prior to the end of the course informing you that the survey site ( is open along with instructions for accessing the site. Login using your Campus Pipeline ( ) 'CPIPE' username and password. This is the same username and password you use for WebCT. Simply click on the course that you wish to evaluate and enter the information. All responses are strictly anonymous. We especially encourage you to clarify your position on any of the questions and give explicit feedbacks on your overall evaluations in the section at the end of the formal survey which allows for written comments. We ask that you submit your survey prior to the last class. Course Schedule Course schedule will be posted online ( Make sure to regularly consult the web page for an updated schedule.
