The tutorials will be held in the Lower Level (B2) of the Trinity Biomedical Sciences Institute.
The ICWSM-12 Committee is pleased to present the Tutorials Day program for the Sixth International Conference on Weblogs and Social Media (ICWSM-12), to be held Monday, June 4, 2012 in Dublin, Ireland. The Tutorials Day provides an opportunity for junior and senior researchers to spend a day before ICWSM freely exploring exciting advances in disciplines outside their normal focus.

For all the wonderful things we hear about how compute clusters enable the analysis of massive datasets, the sad truth is that few researchers can use them. This is due to practical issues: clusters are expensive, their administration requires non-trivial time and technical knowledge, and the tools for using them aren't user friendly. Nonetheless, the average size of network-based datasets is growing. This means that more and more researchers need to do large network analysis but don't have a cluster at their disposal.
In this tutorial, we will teach attendees several easy-to-use strategies for analyzing large social network datasets (upwards of millions of nodes and edges with metadata) on a desktop or high-power laptop. These strategies involve using a combination of tools and techniques that capitalize on their individual strengths.
Over the course of the tutorial, attendees will first learn how to use several python-based libraries for large-scale data and network analysis as well as easy ways to store data to flat-files to minimize retrieval time. Then we will discuss how to combine these tools together. Finally, we will use the newly learned approaches to analyze two large network datasets.
Bio: Derek Ruths is a Computer Science professor at McGill University. Much of his current work involves analysis and modeling of large networked datasets from online social platforms and general ontologies. He likes clusters, but believes that laptops and desktops (but not iPads) can do large-scale network analysis too.

Networks are a data structure common found across all social media services that allow populations to author collections of connections. The Social Media Research Foundation's NodeXL project makes analysis of social media networks accessible to most users of the Excel spreadsheet application. With NodeXL, Networks become as easy to create as pie charts. Applying the tool to a range of social media networks has already revealed the variations present in online social spaces. A review of the tool and images of Twitter, flickr, YouTube, and email networks will be presented.
Bio: Marc Smith is a sociologist specializing in the social organization of online communities and computer mediated interaction. Smith leads the Connected Action consulting group and lives and works in Silicon Valley, California. Smith co-founded the Social Media Research Foundation, a non-profit devoted to open tools, data, and scholarship related to social media research.
Smith received a B.S. in International Area Studies from Drexel University in Philadelphia in 1988, an M.Phil. in social theory from Cambridge University in 1990, and a Ph.D. in Sociology from UCLA in 2001. He is an adjunct lecturer at the College of Information Studies at the University of Maryland. Smith is also a Distinguished Visiting Scholar at the Media-X Program at Stanford University.
To become or remain successful, online communities and networks must meet a number of challenges that are common to many groups and organizations, offline as well as online. For example, online communities must handle the start-up paradox, when early in their lifecycle they have few members to generate content and little content to attract members. Throughout their lifecycle, they must recruit and socialize newcomers, encourage commitment and contribution from members, solve problems of coordination and encourage appropriate behavior among members and interlopers alike.
The social sciences tell us a lot about how to make thriving online communities. Economics and various branches of psychology offer theories of individual motivation and of human behavior in social situations. The theories generalize from observations of naturally occurring behavior, from controlled experiments, and from abstract mathematical models. Properly interpreted, they can inform choices about how to meet the challenges described above. This tutorial will focus in particular on problems of encouraging contributions and getting new communities to critical mass.
It is based on selected sections of a book, co-authored with Robert Kraut, on using the social sciences as a guide to designing online communities. Building Successful Online Communities: Evidence-based Social Design. (MIT Press, 2012).

The proliferation of user generated content on the Web is driving a new wave work on the determination of user sentiment from web texts such as message boards, blogs, tweets, and Facebook status updates. Both researchers and practitioners are developing and applying new methods to determine how users feel about everything: products and politicians, friends and family, scientific articles and celebrities This tutorial will cover the state of the art in this rapidly growing area, including recent advances that combine information extraction with sentiment analysis to improve accuracy in assessing sentiment about specific entities. We will present several real world applications of sentiment analysis. Special emphasis will be given to lessons learned from years of experience in developing real world sentiment analysis systems.

More and more regular users use to blogosphere to express and discuss their opinions, the facts, events, and ideas pertaining to their own lives, their community, their profession, or society at large. It goes without saying that being able to extract reliable data from this medium opens the door to the most varied kinds of analysis and using datasets of massive proportions. As a result, a great deal of attention has been devoted lately to applying information extraction to the blogosphere. In this tutorial, I focus on a specific sub-problem: extracting information networks which act as summaries of the blogosphere as a whole. These networks consist of nodes representing entities and edges representing the relationship between such entities. I will cover fundamental tools from NLP and network science that allow the unsupervised extraction information networks from social media content.
