NTCIR-11 Cooking Recipe Search Task
1. Task name and short name
The task name is Cooking Recipe Search. The short name is RecipeSearch.
2. Task type (core challenge or pilot)
NTCIR-11 RecipeSearch is an additional pilot task.
3. Task description
Information access tasks involving food have traditionally focused on locating
or ranking relevant restaurants given a user’s information need. However, home
cooking remains a fundamental method for acquiring a meal. In this pilot task, we
propose exploring the information access tasks associated with cooking recipes.
Japanese/English recipe search collections will be constructed in this task.
In RecipeSearch, we selected the following two sub-tasks to study.
[1] The first subtask, ad-hoc search, considers the scenario where a user searches
for a recipe using a natural language question.
This includes straightforward queries such as 'curry rice' as well as more
complicated queries such as 'curry rice without gluten'.
We expect these constraints to be common in real world queries due to dietary
restrictions and limited availability of some ingredients.
[2] The second subtask, recipe pairing, considers the scenario where a user
searches for a complementary recipe (side dish) to a query recipe (main dish).
For example, a user may be interested in 'recipes complementing curry rice',
such as a soup, salad, or dessert. This sub-task, although similar to IR tasks
such as diversification and contextual suggestion, focuses on the unique properties
of cooking and eating.
Dataset (corpus & queries)
Rakuten Recipe contains 440,000 Japanese recipes. Yummly Recipe Data contains
100,000 English recipes. For subtask1 (ad-hoc search), 500 Japanese queries and
500 English queries are used for the evaluation. Each of the queries is associated
with a sample relevant recipe. Each of the queries contain simple keywords.
For subtask2 (recipe pairing), 100 Japanese queries and 100 English queries are used
for the evaluation. Each of the query contains a recipe of main-dish (meat, pasta, etc.)
as context information. A recipe of side-dish (a soup, salad, or dessert) is information
need that users want to search for. For more details, see corpus & queries.
Judgements (relevance assessment)
Participants are expected to generate ranked recipe lists (called as "runs"), and
submit them to TOs. Please note that participants in this task is requested to give
manual judgments to develop official judgements data in the RecipeSearch task.
Participants may employ students to do this process.
