Preface

This volume contains the post-proceedings of the ESWC 2013 conference, whichtook place in Montpellier, France, from during 26h–30th, 2013.

The conference was without doubt a great success and attracted a total num-ber of 300 participants. Besides the presentations given in the research tracks 1,the conference featured a rich and broad tutorial and workshop program con-sisting of 11 workshops and 7 tutorials.

A short paper by the tutorial and workshop chairs providing an overview ofthe tutorial workshop program is included in this volume.

Further, 20 posters and 24 demonstrations were presented at the poster anddemonstration sessions, respectively. This volume contains the 44 papers de-scribing the posters and demonstrations. While demonstration papers are up to5 pages long, poster papers are shorter with 2 pages maximum. A short overviewof the demonstration and poster session is also included in this volume.

Further, the volume also contains the 10 best workshop papers, which wereselected by the workshop chair and the general chair on the basis of their reviewsand nominations by the workshop chairs. The authors of these workshop papersalso received the opportunity to do a lightning presentation on their work at thelast day of the conference.

Finally, the volume contains four papers of the AI Mashup Challenge 2. Theywere peer-reviewed after the corresponding systems had been presented at theconference in the AI Mashup Challenge track.

We hope you enjoy the volume!
