Course Description

This course is self-contained, and gives the essential background for social computing. The course provides an introduction to the rich variety of social computing applications, some already popular and some emerging. It identifies the key concepts underlying such applications highlighting the main paradigms of social computing.

This course understands social computing in a broad sense. In this conception, people and organizations are social entities and social computing arises from the interplay between computing on the one hand and social relationships among social entities on the other hand. Specifically, this course considers how (1) social relationships and individual preferences can be modeled, represented, and reasoned about through computing technology and (2) how interactions among social entities can be incorporated into computations as a basis for solving problems. This course surveys the key paradigms exhibited by applications of social computing. It identifies concepts for modeling and realizing social computing applications.

This course is being offered in two editions, as CSC 455 and CSC 555. All the requirements of CSC 455 apply to CSC 555. In addition, CSC 555 students must produce a term paper describing a research topic related to the course.

The research topic could be an elaboration of the main project you work on, a review of the literature on specific aspect of social computing, or your original contributions. There will be opportunities to discuss the term paper (including a brief proposal and draft versions) with me. My hope is that this paper will eventually be of use to you in some additional way, e.g., in your thesis or dissertation, or your PhD written prelim. Please discuss any potential overlap of your paper with your other work with me and report it within your term paper.

Learning Outcomes

Upon completion of this course, students will be able to do the following.

• Understand the range of social computing applications and concepts.
• Understand and apply concepts of computational models underlying social computing
• Carry out simple forms of social analytics, involving network and language models, applying existing analytic tools on social information.
• Design and launch social computing applications.
• Understand the broad aspects of, and implement, richer social computing models in social computing applications.
• Evaluate emerging social computing applications, concepts, and techniques in terms of key principles.

Readings and software

• Required: Transparencies. Available on the course website. I will announce the availability of the final versions throughout the semester.
• Required: Readings. Available openly, through the university library, or from the course website.
• All necessary software will be available for use on NCSU laboratory computers or for free download for academic purposes.

Grading

I will assign +/- grades. There will be a fair amount of work—please plan to spend about eight hours (plus time in class) each week.

The following programming assignments jointly add up to the programming component of the course grade in the above table. The weights of the assignments are based on their expected complexity. I may change the weights as the semester progresses.

CSC 555 students must submit a term paper worth approximately 9% of the total grade for them. A general-purpose rubric for term papers is here. However, if you base your term paper on the same topic as your semester project, you can submit it merely by extending your final project report by two pages. The project-based option will turn out to be far less work for you, in general.

Prerequisite

The course is self-contained. The main informal prerequisite is maturity in thinking about subtle concepts, such as might be gained through experience with conceptual modeling in databases or software.

From long experience, I have discovered that the material in CSC 226 is essential for my courses. Here is a (partial) list of topics that will be assumed: elementary set theory, relations, partial orders, functions, concept of a theorem, propositional logic, and predicate logic.

I recommend you brush up on these topics if you aren't comfortable with them. These topics are covered in CSC 226: Applied Discrete Mathematics. You may review Chapters 1 to 6 from the following book, which is sometimes used as the CSC 226 textbook:
