Paper Format Please prepare your paper in English using the Lecture Notes in Computer Science (LNCS) template, which is available here . Papers must be submitted in PDF. Types of Submissions When submitting a paper to LION14, authors are required to select one of the following three types of papers:

  • Long paper: original novel and unpublished work (max. 15 pages in LNCS format);
  • Short paper: an extended abstract of novel work (max. 6 pages in LNCS format);
  • Work for oral presentation only (no page restriction; any format). For example, work already published elsewhere, which is relevant and which may solicit fruitful discussion at the conference.

If you are submitting for a special session, please remember to specify the Special Session number in the title of your submission, like: SUBMITTED TO SPECIAL SESSION NN Submission System: All papers must be submitted using EasyChair (
