12th of September 2011: Contest.


The main rule, common for all challenges, is: “you have to use the initial recipe book as a starting point to provide adapted recipes”. You are allowed to use any other knowledge source to bootstrap your system, gather adaptation knowledge, compute similarities measures, build ontologies, etc.

1. Main Challenge

As in the previous editions of the competition, the main challenge involves answering queries that require the selection and possible modification of a recipe for a single dish. For example “I would like a fish filet, but please avoid lemon and other citrus fruits.”

Systems must be able to deal with:

2. Adaptation Challenge

The aim of the adaptation challenge is to focus the adaptation task.

Given a recipe from the recipe base, and a set of constraint, teams will have to build an adapted recipe.


3. Open Challenge

The rule of the open challenge is quite simple: do what you want (still with the initial case base) and impress us! The only evaluation criterion for this challenge is the scientific originality of the proposed contribution. The evaluation will rely on the peer review of the paper, your presentation, and your demo during the contest. You can present one specific aspect of a system as a candidate for the open challenge.

Here are some example of topics that you can address in the open challenge (non-exhaustive list):

Look at it carefully : an open challenge this year may become an official challenge for next year…

4. Student Challenge

Students teams (or student-led teams) are welcome. Students teams can focus on a specific task (e.g., natural language processing of a query, quantity adaptation, adaptation knowledge acquisition, etc.) and present their results during the contest.

Students' contributions will be evaluated separately by the Program Committee and the best student team will receive a special award.
