Description

When you enroll for courses through Coursera you get to choose for a paid plan or for a free plan

  • Free plan: No certicification and/or audit only. You will have access to all course materials except graded items.
  • Paid plan: Commit to earning a Certificate—it's a trusted, shareable way to showcase your new skills.

This course will use social network analysis, both its theory and computational tools, to make sense of the social and information networks that have been fueled and rendered accessible by the internet.

About the Course

Everything is connected: people, information, events and places, all the more so with the advent of online social media. A practical way of making sense of the tangle of connections is to analyze them as networks. In this course you will learn about the structure and evolution of networks, drawing on knowledge from disciplines as diverse as sociology, mathematics, computer science, economics, and physics. Online interactive demonstrations and hands-on analysis of real-world …

About the Course

Everything is connected: people, information, events and places, all the more so with the advent of online social media. A practical way of making sense of the tangle of connections is to analyze them as networks. In this course you will learn about the structure and evolution of networks, drawing on knowledge from disciplines as diverse as sociology, mathematics, computer science, economics, and physics. Online interactive demonstrations and hands-on analysis of real-world data sets will focus on a range of tasks: from identifying important nodes in the network, to detecting communities, to tracing information diffusion and opinion formation.

About the Instructor(s)

Lada Adamic is an Associate Professor in the School of Information and the Center for the Study of Complex Systems at the University of Michigan. She holds a PhD in Applied Physics from Stanford, where she conducted some of the first studies of online social networks. Adamic created the course "Networks: Theory and Application", which she has been teaching since 2006. She has received an NSF Career Award to fund her research on the social dynamics of information, and a University of Michigan Henry Russell award in recognition of her teaching and research.

Course Syllabus

Week 1: What are networks and what use is it to study them? Concepts: nodes, edges, adjacency matrix, one and two-mode networks, node degree Activity: Upload a social network (e.g. your Facebook social network into Gephi and visualize it ). Week 2: Random network models: Erdos-Renyi and Barabasi-Albert Concepts: connected components, giant component, average shortest path, diameter, breadth-first search, preferential attachment Activities: Create random networks, calculate component distribution, average shortest path, evaluate impact of structure on ability of information to diffuse Week 3: Network centrality Concepts: betweenness, closeness, eigenvector centrality (+ PageRank), network centralization Activities: calculate and interpret node centrality for real-world networks (your Facebook graph, the Enron corporate email network, Twitter networks, etc.) Week 4: Community Concepts: clustering, community structure, modularity, overlapping communities Activities: detect and interpret disjoint and overlapping communities in a variety of networks (scientific collaborations, political blogs, cooking ingredients, etc.) Week 5: Small world network models, optimization, strategic network formation and search Concepts: small worlds, geographic networks, decentralized search Activity: Evaluate whether several real-world networks exhibit small world properties, simulate decentralized search on different topologies, evaluate effect of small-world topology on information diffusion. Week 6: Contagion, opinion formation, coordination and cooperation Concepts: simple contagion, threshold models, opinion formation Activity: Evaluate via simulation the impact of network structure on the above processes Week 7: Cool and unusual applications of SNA Hidalgo et al. : Predicting economic development using product space networks (which countries produce which products) Ahn et al., and Teng et al.: Learning about cooking from ingredient and flavor networks Lusseau et al.: Social networks of dolphins others TBD Activity: hands-on exploration of these networks using concepts learned earlier in the course Week 8: SNA and online social networks Concepts: how services such as Facebook, LinkedIn, Twitter, CouchSurfing, etc. are using SNA to understand their users and improve their functionality Activity: read recent research by and based on these services and learn how SNA concepts were applied

Recommended Background

There are no math or programming prerequisites for the class. There will be a few additional assignments for those with a programming background, which will use the R statistical programming language along with NetLogo.

Suggested Readings

If you’d like to get a head start, download Gephi and explore some of its tutorials. To explore networks interactively, you can visit the NetLogo demonstrations. If you’re itching to read, the Easley and Kleinberg free text on Networks, Crowds and Markets is excellent. The chapters pertinent to this class are 1-5, 13-14,19-21.

Course Format

The class will consist of lecture videos, which are between 8 and 12 minutes in length. These contain 1-2 integrated quiz questions per video. There will also be standalone homeworks that are not part of video lectures, optional programming assignments, and a (not optional) final exam.

FAQ

  • What tools will we be using in this class?

    We will be using Gephi for visualization and analysis. The interactive demonstrations will be primarily in NetLogo, which you will be able to access through your web browser. If you would like to complete the programming assignments, which will be done in NetLogo and R, NetLogo is freely available here and R is freely available here.

  • Will I get a certificate for completeing this class?
  • Yes. Students who successfully complete this class will get a certificate signed by the instructor.
