KMi students joined more than 50 others from Europe and beyond in Spain last month for the third Summer School on Ontological Engineering and the Semantic Web (SSSW05). Co-directed by Enrico Motta (KMi) and Asun G�mez-P�rez (UPM) the school covered topics such as ontology mapping and alignment, semantic web services, and human language technologies. As well as invited talks from top speakers in the field, the school took an interactive approach to learning with students involved in hands-on sessions, mini-projects, and poster sessions. Needless to say, the intense intellectual work was complimented by a top-class social programme.
