Ομιλητής: Professor Ricardo Baeza Yates

Τίτλος ομιλίας: The Web: Wisdom of Crowds or Wisdom of a Few?

Περίληψη/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 two billion people that use it. In this ocean of hyperlinked
data there is explicit and implicit information and knowledge. But how
is the Web? What are the activities of people? How
content is generated? Web data mining is the main approach to answer
these questions. 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. In this presentation we explore the wisdom of crowds in relation
to several dimensions such as bias, privacy, scalability, and spam. We
also cover related concepts such as the long tail of the special
interests of people, or the digital desert, content that nobody sees.
