Introduction

Knowledge technologies aim to provide meaning to the petabytes of information content that our multilingual societies will generate in the near future. Specifically, a wide range of advanced techniques are required to progressively automate the knowledge lifecycle. These include analyzing, and then automatically representing and managing, high-level meanings from large collections of content data. However, to be able to build the next generation of intelligent open-domain knowledge application systems, we need to deal with concepts rather than words.
