This course discusses advanced topics from the field of network science. It builds on the topics that have been discussed in Web Science and Web Technology (707.000) course. Among other we will discuss the topics of network evolution and the connection between network structure and its function.
In recent years a new multidisciplinary research field Network Science emerged from various traditional fields such as computer science, physics, social science, or information theory. The researches in many fields recognized the nessecity to investigate not only properties of individuals but also their connections with other individuals. For example, the famous "Six Degrees of Separation" phenomenon from social sciences can be only explained by the existence of specific structural properties of social networks. Yet another example involves e.g. the success and growth of technologies such as the Internet or the Web. This fastest growth of any technology in the human history can be explained by simple dynamic properties (e.g. preferential attachment) of the network representations of the Internet and the Web.
In this course we will investigate and discuss some of such advanced questions in modern networks. In particular, we will mostly deal with information networks.
Course topics include:
In this course the students will:
At the end of this course the students will know how to:
Projects and excercises will be discussed during lectures. We will try to find projects which are interesting and funny for both students and us ;-)
The total number of points that can be reached will be 80.
The grading scheme is as follows:
You should pose questions about a particular network, e.g. is it assortatively mixed, what is the correlation between in- and out-degree of nodes, etc. You should then select network measures, calculate them for a desired network and provide answers to the questions.
Then, prepare 3 slides for the discussion:
Send me the slides per e-mail as a PDF file until 17.11.2016 24:00. Subject of the e-mail must include [NetSci].
You should model a desired process taking place on a network, e.g. how information spreads over Twitter, the flow of passengers in a traffic system, etc. You decide on the methodology how to examine the process, e.g. by simulation, analytically, or a combined appraoch. For a desired network you perform experiments, obtain results and finally discuss the results. Alternatively, you may implement a community detection algorithm using e.g. an MCMC approach such as simulated annealing.
Then, prepare 5 slides for the discussion:
Send me the slides per e-mail as a PDF file until 02.02.2017 24:00. Subject of the e-mail must include [NetSci].
