The International RuleML Symposium on Rule Interchange and Applications

Orlando, Florida: October 30-31, 2008

Additional Calls for Contributions

RuleML-2008 Challenge/Showcase Demos

The RuleML-2008 Challenge addresses system demonstrations showcasing the practical use of rule technologies in distributed and/or Web-based environments. The focus of the challenge is on rule technologies (including rule languages and engines), interoperation, and interchange. The challenge offers participants the chance to demonstrate their commercial and open source tools, use cases, and applications. Prizes will be awarded to the two best applications. All accepted demos will be presented in a special Challenge Session.

A submission to the RuleML-2008 Challenge has to meet the requirement that explicit (declarative) rules play a central role in the application. For the 2008 Challenge this means that:

  • Rules are available in the explicit representation of a declarative format and are decoupled from the application (rather than only existing in a form that is compiled or hard-coded into the application logic).
  • Rules are used in interesting and practically relevant ways, e.g. to derive new information, transform knowledge, provide decision support; or, to enable automated monitoring, enforcement, validation, or management of the logic of an application.

The demo should preferably (but not necessarily) be embedded into a web-based or distributed environment so that there will be a need for features related to the RuleML symposium topics.

Submissions to the RuleML Challenge 2008 consist of (1) a link to information about the demo/showcase, e.g. a project site, an (embedded link to an) online demonstration, a presentation, or a download site and (2) demo description material (up to 3 pages), which can be either in the form of a paper (e.g., in LNCS format) and/or contain other descriptive material. The demo description material will be distributed at the Symposium as part of the official Symposium handouts and it will be published at the Symposium's Web site. The demo description material will be subject to evaluation, so the material should contain a substantial presentation of the system to enable a proper evaluation of the techniques used.

The demo link should be submitted through the Challenge Website, while the demo paper should be submitted as a pdf file by email to: with the text 'Submission to RuleML-2008 Challenge' in the subject by October 1, 2008. After the submission of the demo link, it will be immediately available on the Web, which can provide instant visibility to information about demos/showcases. If the (embedded) link to your demo/showcase is password-protected, then please submit a password for anonymous login from any Web browser, giving us the permission to pass the password on to 3 PC members.

Decisions will be notified by October 6th. The demos/showcases themselves will be evaluated during RuleML-2008, and prizes will be awarded to the first two best applications.

Lightning Talks

A lightning talk is a five-minute presentation on any topic of interest to the RuleML community; it can be a new idea, a technology, an evaluation, an observation, a complaint, an explanation, a suggestion, a report of success or failure, a call to action, a description of a technique, or a lament. In general, it is supposed to be a short visionary talk which should initiate discussion. If you are a rule developer working on an exciting project and you do not have the time to submit a full paper, Lightning talks are a great way to interact with the RuleML community and receive feedback on your ideas. Lightning talks are presented back-to-back with a strictly enforced five minute limit, so make sure that you can fit your presentation within this time span.

People interested at giving a lightning talk during RuleML-2008 should show their their interest by sending an email to by October 1, 2008, including a title and a 250-word abstract of their intended talk.

Decisions will be notified by October 6th.

Highlight Talks

We invite the submission of outstanding full papers that have been published between 2007 and the submission deadline (October 1, 2008). Publications that are "in press" and already linked on the journal web site are also welcome. A group of experts will select the papers to be presented at the meeting considering the impact of the work on the field, the likelihood that the work makes a good presentation, and the relevance for the topics of RuleML-2008, in general.

Submissions should be sent directly to the RuleML-2008 chairs at by October 1, 2008, and must include the following:

  • Name/affiliation/email of submitter (assumed to be the presenter; note that the presenter cannot change because the identity and ability to present of that person will be an essential selection criterion).
  • Names/affiliations/email of ALL coauthors (note: any name appearing on a published paper has to be added here). Note that all co-authors have to agree to the submission and that it is the responsibility of the submitter to guarantee that all co- author email addresses are correct (email notifications of the submission will be sent to all co-authors).
  • Additional contact information (for presenter).
  • A 250-word abstract-like argument that explains how the submitted paper(s) suit the goal of presenting highlights that impacted the field.
  • Sources of original publication(s) (Year, Journal, Vol., pages).
  • PDF with paper(s) (note: in case of the submission of 2 papers, both have to be merged into one single PDF; all reviews will be based on the content of this PDF).
  • Optional: link to Google Video demonstrating presentation skills of presenter.
  • Note that we will need PDF submissions; the system will neither be able to handle ASCII, nor Word, nor LaTeX, nor anything other than standard PDF. It is the responsibility of the submitter to verify that the PDF is completely viewable/printable by all major operating systems (LINUX, MacOS, Windows).
  • Each presenter can submit a maximum of one application to present a highlight. The maximal number of submissions per author/co-author is 5.

All submissions will be evaluated by a group of reviewers. Reviewers will consider the following criteria:

  • Relevance, interest, and value of the topic to RuleML-2008 attendees,
  • Impact of the paper(s) on rules (while the impact of papers on science is not fully reflected by ISI/Google-like impact factors or high number of downloads, high values in such factors will clearly stand as a strong argument for acceptance),
  • "Presentability" of the work to a large, diverse audience,
  • Quality of oral presentations by the submitter (if none).

These "soft" criteria attempt to capture the underlying concept, namely the presentation of exciting and thought-provoking seminars that will both contribute to the success and attraction-value of RuleML-2008 and to the impact the meeting has on advancing rule interchange and applications. The criterion of "presentability" accounts for the fact that some papers that will completely change the field, or will become citation records may not translate to exciting seminars.

The selected Highlights will be presented in a special track during the RuleML-2008 Symposium. All presentations will have to be completed within 20 minutes and will be followed by 5-minute discussions. While presenters are expected to focus mostly on the chosen paper(s), short infusions of more recent data are welcome.

Decisions will be notified by October 6th.

Fast Abstracts

Fast Abstracts at RuleML-2008 are short presentations, either on new ideas or work in progress, or radical opinions that can address any issue relevant to RuleML-2008. Fast Abstracts provide an opportunity to receive early feedback from the community. Contributions are particularly solicited from industrial practitioners and academics that may not have been able to prepare full papers, but seek an opportunity to engage with the RuleML community.

Fast Abstracts should be 4-pages long, and must be formatted in LNCS format. The submission deadline is October 1, 2008. Submissions should be sent directly by email to, and they will be refereed on the relevance to RuleML 2008, but also on their novelty of idea and/or on their capacity to stimulate and intrigue the reader. Accepted contributions will be published in electronic form (at the Symposium's Web site and on CD), and an author will deliver a short talk in the Fast Abstracts track at the conference. Decisions will be notified by October 6th. Authors of accepted fast abstracts must provide the camera ready version by October 10th. At least one author of each accepted Fast Abstract is expected to register to the conference.
