如何调度Amazon Mechanical Turk HIT?求每周五定时执行的可行方案
Scheduling Amazon Mechanical Turk HITs (and Alternatives) Without IFTTT/Zapier
Great question—scheduling MTurk HITs on a recurring basis (like every Friday morning) is totally doable, even without IFTTT or Zapier. Below are the most reliable, core-function-focused solutions:
1. Official MTurk API + AWS EventBridge (Most Reliable)
This is the gold standard since it’s directly integrated with AWS, no third-party middlemen. Here’s how to set it up:
- Use the AWS SDK (e.g., Python’s
boto3) to write a script that creates your HIT programmatically. A basic snippet might look like this:import boto3 mturk = boto3.client('mturk', region_name='us-east-1') # MTurk's primary region # Define your HIT parameters hit_response = mturk.create_hit( Title='Your HIT Title', Description='Your HIT Description', Keywords='keyword1, keyword2', Reward='0.50', # In USD MaxAssignments=10, LifetimeInSeconds=86400, # 1 day AssignmentDurationInSeconds=300, # 5 minutes Question='<XML or HTML for your HIT task>' # Follow MTurk's question format ) - Schedule the script with AWS EventBridge: Create a rule that triggers a Lambda function (which runs your
boto3script) every Friday at your desired time. Set the cron expression to something like0 9 * * 5(adjust for your timezone—EventBridge uses UTC by default, so convert your local time accordingly). - Permissions note: Make sure your Lambda execution role has the
mturk:CreateHITpermission, and your MTurk account is linked to AWS correctly.
2. Third-Party MTurk Management Tools
If you prefer a no-code approach, several paid tools built for MTurk offer built-in scheduling:
- CloudResearch: Formerly TurkPrime, this platform lets you schedule HITs to go live at specific times (including recurring weekly schedules) through its web interface. It handles all the API heavy lifting for you.
- MTurk Suite: A browser extension with advanced features—while it’s primarily for managing active HITs, it has scheduling capabilities for queuing and releasing HITs at set times.
3. Custom Script + Server-Side Scheduling
If you want full control without AWS services, you can host your own script on a low-cost cloud server:
- Write your HIT creation script (using
boto3or another SDK) and upload it to a server (e.g., AWS EC2, DigitalOcean Droplet). - Use cron (Linux/macOS) or Task Scheduler (Windows) to run the script on your desired schedule. For cron, the expression
0 9 * * 5will run it every Friday at 9 AM server time—just ensure the server’s timezone matches your needs. - Pro tip: Use a small, always-on server (like a t2.micro on AWS, which is eligible for the free tier) to avoid having to keep your local machine running.
4. Alternative Crowdsourcing Platforms with Built-In Scheduling
If you’re open to moving beyond MTurk, these platforms have native scheduling features as core functionality:
- Clickworker: Lets you schedule tasks to go live at specific dates/times, including recurring weekly schedules. It has a global workforce and supports a variety of task types.
- Appen (formerly Figure Eight): Offers managed task scheduling for both small and large-scale projects, with options to set recurring launch times.
Key Notes
- Always test your schedule with a small test HIT first to verify timing and task setup.
- Double-check timezones—most scheduling tools use UTC by default, so adjust accordingly to hit your Friday morning window.
- For MTurk, ensure you’re using the correct region (us-east-1 is the main one for most users) and have sufficient funds in your account to cover rewards.
