AWS CLI Command Reference

[ aws . mturk ]

create-hit

Description

The CreateHIT operation creates a new Human Intelligence Task (HIT). The new HIT is made available for Workers to find and accept on the Amazon Mechanical Turk website.

This operation allows you to specify a new HIT by passing in values for the properties of the HIT, such as its title, reward amount and number of assignments. When you pass these values to CreateHIT , a new HIT is created for you, with a new HITTypeID . The HITTypeID can be used to create additional HITs in the future without needing to specify common parameters such as the title, description and reward amount each time.

An alternative way to create HITs is to first generate a HITTypeID using the CreateHITType operation and then call the CreateHITWithHITType operation. This is the recommended best practice for Requesters who are creating large numbers of HITs.

CreateHIT also supports several ways to provide question data: by providing a value for the Question parameter that fully specifies the contents of the HIT, or by providing a HitLayoutId and associated HitLayoutParameters .

Note

If a HIT is created with 10 or more maximum assignments, there is an additional fee. For more information, see Amazon Mechanical Turk Pricing .

Options

--max-assignments (integer)

The number of times the HIT can be accepted and completed before the HIT becomes unavailable.

--auto-approval-delay-in-seconds (long)

The number of seconds after an assignment for the HIT has been submitted, after which the assignment is considered Approved automatically unless the Requester explicitly rejects it.

--lifetime-in-seconds (long)

An amount of time, in seconds, after which the HIT is no longer available for users to accept. After the lifetime of the HIT elapses, the HIT no longer appears in HIT searches, even if not all of the assignments for the HIT have been accepted.

--assignment-duration-in-seconds (long)

The amount of time, in seconds, that a Worker has to complete the HIT after accepting it. If a Worker does not complete the assignment within the specified duration, the assignment is considered abandoned. If the HIT is still active (that is, its lifetime has not elapsed), the assignment becomes available for other users to find and accept.

--reward (string)

The amount of money the Requester will pay a Worker for successfully completing the HIT.

--title (string)

The title of the HIT. A title should be short and descriptive about the kind of task the HIT contains. On the Amazon Mechanical Turk web site, the HIT title appears in search results, and everywhere the HIT is mentioned.

--keywords (string)

One or more words or phrases that describe the HIT, separated by commas. These words are used in searches to find HITs.

--description (string)

A general description of the HIT. A description includes detailed information about the kind of task the HIT contains. On the Amazon Mechanical Turk web site, the HIT description appears in the expanded view of search results, and in the HIT and assignment screens. A good description gives the user enough information to evaluate the HIT before accepting it.

--question (string)

The data the person completing the HIT uses to produce the results.

Constraints: Must be a QuestionForm data structure, an ExternalQuestion data structure, or an HTMLQuestion data structure. The XML question data must not be larger than 64 kilobytes (65,535 bytes) in size, including whitespace.

Either a Question parameter or a HITLayoutId parameter must be provided.

--requester-annotation (string)

An arbitrary data field. The RequesterAnnotation parameter lets your application attach arbitrary data to the HIT for tracking purposes. For example, this parameter could be an identifier internal to the Requester’s application that corresponds with the HIT.

The RequesterAnnotation parameter for a HIT is only visible to the Requester who created the HIT. It is not shown to the Worker, or any other Requester.

The RequesterAnnotation parameter may be different for each HIT you submit. It does not affect how your HITs are grouped.

--qualification-requirements (list)

Conditions that a Worker’s Qualifications must meet in order to accept the HIT. A HIT can have between zero and ten Qualification requirements. All requirements must be met in order for a Worker to accept the HIT. Additionally, other actions can be restricted using the ActionsGuarded field on each QualificationRequirement structure.

(structure)

The QualificationRequirement data structure describes a Qualification that a Worker must have before the Worker is allowed to accept a HIT. A requirement may optionally state that a Worker must have the Qualification in order to preview the HIT, or see the HIT in search results.

QualificationTypeId -> (string)

The ID of the Qualification type for the requirement.

Comparator -> (string)

The kind of comparison to make against a Qualification’s value. You can compare a Qualification’s value to an IntegerValue to see if it is LessThan, LessThanOrEqualTo, GreaterThan, GreaterThanOrEqualTo, EqualTo, or NotEqualTo the IntegerValue. You can compare it to a LocaleValue to see if it is EqualTo, or NotEqualTo the LocaleValue. You can check to see if the value is In or NotIn a set of IntegerValue or LocaleValue values. Lastly, a Qualification requirement can also test if a Qualification Exists or DoesNotExist in the user’s profile, regardless of its value.

IntegerValues -> (list)

The integer value to compare against the Qualification’s value. IntegerValue must not be present if Comparator is Exists or DoesNotExist. IntegerValue can only be used if the Qualification type has an integer value; it cannot be used with the Worker_Locale QualificationType ID. When performing a set comparison by using the In or the NotIn comparator, you can use up to 15 IntegerValue elements in a QualificationRequirement data structure.

(integer)

LocaleValues -> (list)

The locale value to compare against the Qualification’s value. The local value must be a valid ISO 3166 country code or supports ISO 3166-2 subdivisions. LocaleValue can only be used with a Worker_Locale QualificationType ID. LocaleValue can only be used with the EqualTo, NotEqualTo, In, and NotIn comparators. You must only use a single LocaleValue element when using the EqualTo or NotEqualTo comparators. When performing a set comparison by using the In or the NotIn comparator, you can use up to 30 LocaleValue elements in a QualificationRequirement data structure.

(structure)

The Locale data structure represents a geographical region or location.

Country -> (string)

The country of the locale. Must be a valid ISO 3166 country code. For example, the code US refers to the United States of America.

Subdivision -> (string)

The state or subdivision of the locale. A valid ISO 3166-2 subdivision code. For example, the code WA refers to the state of Washington.

RequiredToPreview -> (boolean)

DEPRECATED: Use the ActionsGuarded field instead. If RequiredToPreview is true, the question data for the HIT will not be shown when a Worker whose Qualifications do not meet this requirement tries to preview the HIT. That is, a Worker’s Qualifications must meet all of the requirements for which RequiredToPreview is true in order to preview the HIT. If a Worker meets all of the requirements where RequiredToPreview is true (or if there are no such requirements), but does not meet all of the requirements for the HIT, the Worker will be allowed to preview the HIT’s question data, but will not be allowed to accept and complete the HIT. The default is false. This should not be used in combination with the ActionsGuarded field.

ActionsGuarded -> (string)

Setting this attribute prevents Workers whose Qualifications do not meet this QualificationRequirement from taking the specified action. Valid arguments include “Accept” (Worker cannot accept the HIT, but can preview the HIT and see it in their search results), “PreviewAndAccept” (Worker cannot accept or preview the HIT, but can see the HIT in their search results), and “DiscoverPreviewAndAccept” (Worker cannot accept, preview, or see the HIT in their search results). It’s possible for you to create a HIT with multiple QualificationRequirements (which can have different values for the ActionGuarded attribute). In this case, the Worker is only permitted to perform an action when they have met all QualificationRequirements guarding the action. The actions in the order of least restrictive to most restrictive are Discover, Preview and Accept. For example, if a Worker meets all QualificationRequirements that are set to DiscoverPreviewAndAccept, but do not meet all requirements that are set with PreviewAndAccept, then the Worker will be able to Discover, i.e. see the HIT in their search result, but will not be able to Preview or Accept the HIT. ActionsGuarded should not be used in combination with the RequiredToPreview field.

  }
  ...
]

--unique-request-token (string)

A unique identifier for this request which allows you to retry the call on error without creating duplicate HITs. This is useful in cases such as network timeouts where it is unclear whether or not the call succeeded on the server. If the HIT already exists in the system from a previous call using the same UniqueRequestToken, subsequent calls will return a AWS.MechanicalTurk.HitAlreadyExists error with a message containing the HITId.

Note

Note: It is your responsibility to ensure uniqueness of the token. The unique token expires after 24 hours. Subsequent calls using the same UniqueRequestToken made after the 24 hour limit could create duplicate HITs.

--assignment-review-policy (structure)

The Assignment-level Review Policy applies to the assignments under the HIT. You can specify for Mechanical Turk to take various actions based on the policy.

      ]
    }
    ...
  ]
}

--hit-layout-id (string)

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

See ‘aws help’ for descriptions of global parameters.

It’s possible for you to create a HIT with multiple QualificationRequirements (which can have different values for the ActionGuarded attribute). In this case, the Worker is only permitted to perform an action when they have met all QualificationRequirements guarding the action. The actions in the order of least restrictive to most restrictive are Discover, Preview and Accept. For example, if a Worker meets all QualificationRequirements that are set to DiscoverPreviewAndAccept, but do not meet all requirements that are set with PreviewAndAccept, then the Worker will be able to Discover, i.e. see the HIT in their search result, but will not be able to Preview or Accept the HIT.
