Tutorials at ICWSMWe currently have two tutorials scheduled for the afternoon of Saturday, March 25th. The exact time is TBD but it will be in the early afternoon. You must register for the conference and the tutorials to attend. The two tutorials will be one right after the other so you will be able to attend both.
Search and Discovery in the Blogspace
Gilad Mishne and Maarten de Rijke, University of Amsterdam
Pre-Conference Tutorial 1, March 25th
With the increasing number of blogs available, effective ways of searching and exploring blogs are becoming more and more important. The tutorial gives a survey of current activities in the area of blog search and discovery. It identifies important blog search and discovery tasks, describes blog-specific crawling, and then goes on to present effective ways of blog indexing and retrieval methods for addressing these tasks. We also cover several advanced topics in blog search, such as serving advertisements with retrieved results.
The tutorial is organized into three parts. The first part provides information retrieval background, defining concepts and methods used later in the tutorial, as well as surveying a number of publicly-available tools for the task. Additionally, it introduces search scenarios in blogs, deriving the user needs in this domain. The second part focuses on the areas where blog retrieval departs from other retrieval settings: the crawling process, and one search task characteristic of the blogspace identifying opinions and thoughts about a topic. This part also surveys the recent efforts on blog opinion retrieval at TREC 2006. The last part of the tutorial discusses two additional search tasks: blog (rather than blog post) search, and tasks related to the timelined nature of blogs. It also introduces some advanced topics in the area, such as contextual advertising for blogs, and search in social-networking sites.

Spam in Blogs and Other Social Media
Pranam Kolari, Akshay Java, Tim Finin and Anupam Joshi University of Maryland, Baltimore County
Pre-Conference Tutorial 2, March 25th
Spam on the Internet dates back over a decade, with its earliest known appearance as an email about the infamous MAKE.MONEY.FAST. campaign. Spam has co-evolved with Internet applications and is now quite common on the World-Wide Web.
As social media systems such as blogs, wikis and bookmark sharing sites have emerged, spammers have quickly developed techniques to infect them as well. The very characteristics underlying the Web, be it version 1.0, 2.0 or 3.0, also enable new varieties of spam.
This tutorial will detail the problem of spam in social media, with an emphasis on spam in blogs. We will discuss different types of spam, the motivation for spammers and the seriousness and nature of the problem. We will then share some of our discussions with groups facing and tackling this issue. The second half of the tutorial will present an overview of spam detection and elimination efforts with an extensive survey of detecting blog spam. The tutorial will help researchers understand the unique aspects of spam in social media, recognize how it affects analytics and information extraction, and identify current research challenges. For practitioners, it will provide strategies for controlling the problem, and identify areas of collaboration across communities. Background of presenters
