Pool parameters

Parameter

Description

Name

The pool name shown only to you (as a requester) on the project page.

Public description

Will be displayed instead of the project description in the task list for performers and linked training.

Private description

If necessary, you can add a private project description that will only be available to you.

Training

This field is only available if you have training pools in the project.

Training pool that will be linked to the main one.

Pool type

This field should be filled in when you set tasks for 0 cents. Choose an option from the list:

  • Examination — control tasks — to assess how well performers completed their training.
  • Training — tasks with hints — for performers to practice before starting real tasks.
  • Retry — control tasks — to give a second chance to performers who passed the training and exam but made a lot of mistakes while completing main tasks.
  • Other — if none of the above apply.
Level required

This field is only available if you have filled in the Training field.

Percentage of correct responses in training tasks (from 0 to 100) required to be admitted to the pool tasks. The calculation is based on the first responses the performer gave in each task.

Price per task page

Payment per task page in U.S. dollars. For cents, use the dot (".") as a separator. The minimum price is $0.01. For more information, see the Setting up pricing section.

See examples of prices for different types of tasks here.

dynamic pricing

This parameter allows you to vary the task price depending on the performer's skill level. Learn more

See examples of prices for different types of tasks here.

Adult content

Whether the tasks have porn content. Tasks with porn content are only issued to performers who are ready to complete these tasks.

If you didn't check whether the tasks have porn content, select "Yes".

Users filter

By setting the filters, you choose performers that meet your requirements to complete your task. There are filter sets, filters by various criteria, and filters by skills that you can create yourself.

If you are working with Russian-language texts in the task, you don't need to display the project for non-Russian speakers. You can set a filter for the Russian language. Similarly, you can filter performers by place of residence in a particular country or city, and so on. Learn more

If you give training tasks to performers, you can add a skill to the pool to choose performers who already completed training. Learn more about skills.

Non-automatic acceptance

Turn on this option to review the completed tasks manually.

Set the time period when you can check the tasks and reject them if the results are poor.

Learn more about task review here and here.

Captcha frequency

The frequency of captcha display:

  • “No” — Don't show captchas.

  • “Low” — Show a captcha after every 20 task pages.

  • “Medium”/ “High” — Show a captcha after every 10 task pages.

To show the captcha to performers, set the quality control rule.

Review period

The number of days for accepting the tasks (max — 21). The performer will see the deadline for checking the tasks:

  • In the task information on the Yandex.Toloka main page.

  • In the history of completed tasks.

Overlap

The number of performers who should complete each task in the pool.

Configure this parameter if you need several people to complete your task. It is necessary in the tasks that collect photo datasets, require audio recordings, or conduct surveys. Sometimes this improves the quality of results.

To save money, you can set up incremental relabeling.

Incremental relabeling (dynamic overlap) will help you save money. Learn more.

dynamic-overlap

You can use this parameter if you specify fixed values the input data fields. It lets you save your budget and avoid setting fixed overlap for all pool tasks.

You set the range, the service analyzes the responses, their consistency, the level of performers' skills and, if necessary, increases the overlap within the range you specified.

Speed / Quality

Use this setting to select the most active performers by rating or to set the time limit for pool completion.

This way you can choose performers for your tasks. If you want to get responses very quickly, the quality may be doubtful. If you want very high quality, be prepared to wait longer. It is important to find a balance that suits you. Learn more.

Time on task

The time allowed for completing a task page, in seconds. Uncompleted tasks are redistributed to other performers.

We recommend spending no more than 60 seconds per task (including the time for page loading and sending responses).

If you set the interval too long, the tasks will stay open for a long time. If it is too short, the tasks won't be completed and paid for.

Keep task order

The option is disabled (default value)

The uploaded tasks are grouped in pages and given to performers in random order. Within the page, the task order is always random.

Example

If you specified 2 tasks per page when uploading the TSV file with image links to the pool, the system can generate them as follows:

Tasks in the file Page 1 Page 2 Page 3
Image 1 Image 2 Image 6 Image 4
Image 2 Image 5 Image 1 Image 3
Image 3
Image 4
Image 5
Image 6

The option is turned on

Tasks will be grouped in pages in the order they are in the TSV file.
Example

If you specified 2 tasks per page when uploading the TSV file with image links to the pool, you are equally likely to get pages where the first link goes first and the second goes second, and the other way round:

Tasks in the file Page 1 Page 2 Page 3
Image 1 Image 1 Image 3 Image 4
Image 2 Image 2 Image 4 Image 3
Image 3 or or or
Image 4 Image 2 Image 4 Image 5
Image 5 Image 1 Image 3 Image 6
Image 6

If the pool has an overlap, the next task is distributed only when the previous task is completed by the necessary number of performers.

Use this parameter to:

  • Speed up collection of responses for majority vote check.

  • Issue tasks by priority.

    Put important tasks in the beginning of the file. They will be completed faster and with the necessary overlap.

Expires

The date the pool closes. The pool closes automatically on this date, even if the tasks aren't marked up.

Waiting time for the pool to close in seconds

The interval during which the pool will remain open from the moment all tasks are completed. Minimum — 0, maximum — 259200 seconds (three days).

For example, you can use this parameter if you need an open pool where you regularly upload new tasks.

Priority Number from 0 to 100. Allows you to rank a pool within a project. First, a performer is assigned tasks from a pool with higher priority.
