Colloquium: The Web: Wisdom of Crowds and a Long Tail, Prof. Ricardo Baeza-Yates (Yahoo! Research Labs, Spain), Wednesday, November 28, 2012, 15.00-16.00 EET.
The Department of Computer Science at the University of Cyprus cordially invites you to the Colloquium entitled:
The Web: Wisdom of Crowds and a Long Tail
 |
Speaker: Prof. Ricardo Baeza-Yates |
Abstract:
The Web continues to grow and evolve very fast, changing our daily
lives. This activity represents the collaborative work of the millions
of institutions and people that contribute content to the Web as well as
more than one billion people that use it. In this ocean of hyperlinked
data there is explicit and implicit information and knowledge. But how
is the Web? Web data mining is the main task to answer this question.
Web data comes in three main flavors: content (text, images, etc.),
structure (hyperlinks) and usage (navigation, queries, etc.), implying
different techniques such as text, graph or log mining. Each case
reflects the wisdom of some group of people that can be used to make the
Web better. For example, user generated tags in Web 2.0 sites. One important phenomenon of this wisdom is the long tail of the special interests of people. In this talk we cover all these concepts and give specific examples.
