The conference accepts not only full-papers, but also poster and demo short papers. Posters should present work in progress or leading-edge work. Demo papers should describe first-hand experiences with research prototype systems. ECIR has traditionally had a strong student focus, and posters and demos whose sole or main author is a postgraduate student or postdoctoral researcher are especially welcome.

All submissions must be written in English following the LNCS author guidelines and submitted electronically through the conference submission system. Poster and Demo short papers must not be longer than 4 pages. Posters and Demo short papers will be presented at a special posters and demonstrations session. All submissions will be refereed. Posters will undergo double-blind peer review, so authors should take reasonable care not identify themselves in their submissions. Demo submissions will undergo single-blind peer review, so they are not anonymous and should preferably contain a link to an online demo.

To submit a poster or demo short paper, please go to the ECIR 2013 submission site:
