Pool parameters

Parameter

Description

Name

Pool name to be displayed to the requester on the project page.

Public description

If it is filled in, the text will be displayed instead of the project description in the task list for performers.

It will also be displayed for the associated training.

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

Training

The name of the linked training.

Level required

Percentage of correct responses in training tasks (from 0 to 100) required to be admitted to the main 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.

You can define a fixed amount or set dynamic pricing.

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).

Overlap

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

To save money, you can set up dynamic overlap.

Captcha frequency

The frequency of showing captchas:

  • “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. Example:

Closing interval

Waiting time (in seconds) before automatic closure of the pool after all tasks are completed. Minimum — 0, maximum — 259200 seconds (three days).

Use it if:
  • Your data processing is close to real time.
  • You need an open pool where you upload tasks.

Expires

The date the pool closes. The pool closes on this date, even if the tasks aren't completed.

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.

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.
Tasks per page After uploading tasks to the pool using “smart mixing” you can change the number of tasks on the page.

Click the button to configure random check by majority vote.

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".

Offline accept

Turn on the option to check the completed tasks manually.

Deadline

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 Toloka main page.

  • In the history of completed tasks.

Users filter

Filters and skills.

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