This course will cover topics in network analysis, from social networks to applications in information networks such as the internet. We will introduce basic concepts in network theory, discuss metrics and models, use software analysis tools to experiment with a wide variety of real-world network data, and study applications to areas such as information retrieval. For their final project, the students will apply the concepts learned in class to networks of interest to them.
Compared to the PhD level course (SI 708/CS 608), SI 508 will have several in-class lab sessions where we will be analyzing data sets together. It will focus more on applications to the WWW, tagging and blogging, as well as co-authorship and citation networks. It will focus less on mathematical models and algorithms.
SI 708/CS608 will focus more on recent research in the area of complex networks, and may cover these additional topics: network evolution, p* models, strategic network formation, general graph search algorithms, flow, game theory or epidemic modeling.
SI508 and SI708/CS608 will have a joint lecture on Mondays 4-5:30.
Check out a sample of the fall 2007 student projects for inspiration.
