Number of tasks completed

Overview

You can limit the number of tasks in the pool per Toloker, in order to:

  • Get responses from as many Tolokers as possible (for this purpose, set a low threshold, such as one task suite).
  • Protect yourself from robots (for this purpose, the threshold should be higher, such as 10% of the pool's tasks).

Set key values in the quality_control.configs array in the pool settings.

Request body

If a Toloker completes 12 task suites, you can ban them from your project for a given number of days, hours, minutes (at a time or in total) or permanently.

Ban for 10 days

ParameterOverview
configs[]array of objects | required

Array of quality control settings.
configs.collector_configobject | required

Parameters for collecting statistics (for example, the number of tasks skipped in the pool).
configs.collector_config.type

string | required

Criteria for the quality control rule:

  • GOLDEN_SET — The number of correct and incorrect responses in the control tasks.
  • MAJORITY_VOTE — The percentage of responses that matched the majority vote.
  • CAPTCHA — The number of captchas entered successfully and unsuccessfully.
  • INCOME — Payment for tasks completed by the Toloker over the past 24 hours.
  • SKIPPED_IN_ROW_ASSIGNMENTS — The number of task suites skipped in a row.
  • ANSWER_COUNT — The number of task suites completed by the Toloker in the pool.
  • ASSIGNMENT_SUBMIT_TIME — The number of "fast" responses (the minimum response speed is set in the parameters).
  • ACCEPTANCE_RATE — The percentage of Toloker responses that were rejected during manual review.
  • ASSIGNMENTS_ASSESSMENT — The number of assignments accepted or rejected with manual review enabled.
  • USERS_ASSESSMENT — The Toloker's skill value and their bans.
configs.rules.conditionsobject | required

Conditions (for example, 10 task suites skipped in a row). Multiple conditions are combined with the "OR" operator.
configs.rules.conditions.key

string | required

Values that are checked in the condition:

  • assignments_accepted_count — The number of task suites completed by the Toloker.
configs.rules.conditions. operator

string | required

Comparison operator (the key data is compared with the threshold value from value):

  • EQ ("Equal") — Equal to.
  • NE ("Not equal to") — Not equal to.
  • GT ("Greater than") — Greater than.
  • LT ("Less than") — Less than.
  • GTE ("Greater than equal to") — Greater than or equal to.
  • LTE ("Less than equal to") — Less than or equal to.
configs.rules.conditions. valueinteger | required

The threshold value of the variable specified in key.
configs.rules.actionobject | required

The action to perform if conditions are met (for example, block access to the project).
configs.rules.action.type

string | required

Type of action:

  • RESTRICTION — Ban access to projects or pools.

  • SET_SKILL_FROM_OUTPUT_FIELD — Set the "percentage of correct responses" as the skill value (used in control tasks and majority vote rules).

    You can use the skill value for filtering Tolokers.

  • CHANGE_OVERLAP — Change the overlap. For example, to re-assign a task suite to other Tolokers or cancel the recompletion of already accepted assignments.

  • REJECT_ALL_ASSIGNMENTS — Reject all Toloker responses. For example, after a certain number of Toloker responses, it became clear that the Toloker completed tasks poorly.

  • APPROVE_ALL_ASSIGNMENTS — Accept all Toloker responses. For example, if the Toloker completes most tasks well and you are satisfied with this result.

  • SET_SKILL — Assign the specified constant value to the skill.

configs.rules.action. parametersobject | required

Action parameters.
configs.rules.action. parameters.scope

string | required

Scope:

  • POOL — pool. Affects the Toloker's rating.
  • PROJECT — The project. Affects the Toloker's rating.
  • ALL_PROJECTS — All the requester's projects.
configs.collector_config. parametersobject | required if

Required if configs.collector_config.type=``GOLDEN_SET, MAJORITY_VOTE, CAPTCHA, ASSIGNMENT_SUBMIT_TIME.

Parameters for collecting data (depends on the quality control rule specified in the type key).
configs.rules.action. parameters.skill_idstring | required if

Required if type=SET_SKILL_FROM_OUTPUT_FIELD.

ID of the skill to update as tasks are completed.
configs.rules.action. parameters.from_field

string | required if

Required if type=SET_SKILL_FROM_OUTPUT_FIELD.

The value to assign to the skill:

  • correct_answers_rate — The percentage of correct responses.
  • wrong_answers_rate — The percentage of incorrect responses.
configs.rules.action. parameters.skill_valueinteger | required if

Required if type=SET_SKILL_FROM_OUTPUT_FIELD.

A fixed value to assign to the skill (a number from 0 to 100).
configs.rules.action. parameters.deltainteger | required if

Required if type=CHANGE_OVERLAP.

The value determines the amount to change the overlap by.
configs.rules.action. parameters.public_commentstring | required if

Required if type=REJECT_ALL_ASSIGNMENTS.

Comments (the reason for rejecting responses). Available to the requester and the Toloker.
configs.rules.action. parameters.duration_unit

string

Ban duration unit:

  • MINUTES — Minutes
  • HOURS — Hours
  • DAYS — Days
  • PERMANENT — Permanent ban
configs.rules.action. parameters.durationinteger

Ban duration.
configs.rules. action.parameters. private_commentstring

Comments (the reason for blocking access). Visible only to the requester.
configs.rules.action. parameters.open_pool

boolean

Determines whether to re-open a closed pool:

  • true — Open the pool after making changes if it is closed.
  • false — Don't open the pool after making changes, if it is closed.
