Abstract

A vast amount of content is produced by many users every day, but due to
the lack of structure, their contribution is often ignored by other
users. This talk presents approaches such as keyphrase extraction and
link discovery, enabling automatic structure generation for texts, thus
making them more readable.

However, the major challenge of disambiguating word senses is not
tackled. Solving this challenge could improve the proposed approaches
significantly. Especially for the task of link discovery, named entity
disambiguation is a fundamental issue.

The talk introduces Wikipedia as a valuable knowledge repository, for it
is full of named entities. Basically all famous – and not quite as
famous – people have their own Wikipedia article, which are heavily
interconnected (e.g. two actors participated in the same movie). These
interconnection is represented in Wikipedia articles as links and can be
used as input for graph-based named entity disambiguation systems.
