每次 HIT 不能创建超过 10 个作业

Question

我正在使用下面的代码在 Mechanical Turk 上使用 Boto 3 创建 HIT：

new_hit = mturk.create_hit(
    Title='my title',
    Description='my description',
    Keywords='my, keywords',
    Reward='0.02',
    MaxAssignments=25,
    LifetimeInSeconds=9999,
    AssignmentDurationInSeconds=9999,
    AutoApprovalDelayInSeconds=9999,
    Question='''<?xml version="1.0" encoding="UTF-8"?>
<ExternalQuestion xmlns="http://mechanicalturk.amazonaws.com/AWSMechanicalTurkDataSchemas/2006-07-14/ExternalQuestion.xsd">
<ExternalURL>https://myexternalurl/</ExternalURL>
<FrameHeight>540</FrameHeight>
</ExternalQuestion>'''
)

这应该创建一个具有 25 个分配的 HIT。

但是，当我尝试检索结果时，只有 10 个作业：

results = mturk.list_assignments_for_hit(
    HITId='my HIT ID',
    AssignmentStatuses=['Submitted', 'Approved']
)

# This always maxes out at 10
print 'Number of assignments: ' + str(len(results['Assignments']))

我已经用几个不同的 HIT 和几个不同的 MaxAssignments 值试过了。它总是最多进行 10 次分配。似乎 Mechanical Turk 正在默默地将 MaxAssignments 限制在 10。

我在 Mechanical Turk 文档中找到了两条线索。第一：

HITs created with fewer than 10 assignments cannot be extended to have 10 or more assignments. Attempting to add assignments in a way that brings the total number of assignments for a HIT from fewer than 10 assignments to 10 or more assignments will result in an AWS.MechanicalTurk.InvalidMaximumAssignmentsIncrease exception.

https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/mturk.html#MTurk.Client.create_additional_assignments_for_hit.

第二个：

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

https://docs.aws.amazon.com/AWSMechTurk/latest/AWSMturkAPI/ApiReference_CreateHITOperation.html

但这并不能解释为什么我不能在第一个实例中为 MaxAssignments 使用大于 10 的值。我没有收到任何错误。

如何为每个 HIT 创建和检索十个以上的作业？

Answer 1

您是否尝试过指定 MaxResults 参数，如下所示：

response = client.list_assignments_for_hit(
    HITId='string',
    NextToken='string',
    MaxResults=123,
    AssignmentStatuses=[
        'Submitted'|'Approved'|'Rejected',
    ]
)
