<p>At the beginning and end of the lecture we asked you (the students) to characterize the Semantic Web with keywords.<br />
<strong><em>Before</em></strong> the introduction talk:<br />
<img width="450px" alt="" src="http://www.personal-reader.de/semweb08/images/sw-tag-cloud-studenten-vorher.png" title="Semantic Web Tag Cloud (Before)" /></p>
<p><strong><em>After</em></strong> the introduction talk:<br />
<img alt="" src="http://www.personal-reader.de/semweb08/images/sw-tag-cloud-studenten-nachher.png" title="Semantic Web Tag Cloud (After)" width="450px" /></p>
<p>Actually the first <i>tag cloud</i> lists some keywords that describe the idea of the Semantic Web very well (like &#8220;Inhalte-mit-Bedeutung-Verknüpfen&#8221; which means connecting content with meaning, etc.). The second tag cloud was produced after the introduction talk, in which we discussed some standards of the Semantic Web. It lists some of the important Standards that are needed to realize the Semantic Web (like RDF, XML, OWL).</p>
<p>In the Semantic Web lecture we will discuss all Standards in detail. However, we should not forget about the general ideas of the Semantic Web (as partially described in the first tag cloud). </p>
