The attendance to the European Semantic Web Conference 2009 was a great opportunity to see other applications in field of Semantic Web. At the demo sections, I could evidence that a lot of effort is being put on semantic web services, knowledge management using semantic web and different usages of SPARQL for querying expansion. In particular, the panel of tagging and annotation presented related works to what we are doing at AAU. Such works will help me to improve my work as well as to explore other techniques that I had not considered so far.
