require 'rturk'
module Agents
class HumanTaskAgent < Agent
default_schedule "every_10m"
description <<-MD
You can use a HumanTaskAgent to create Human Intelligence Tasks (HITs) on Mechanical Turk.
HITs can be created in response to events, or on a schedule. Set `trigger_on` to either `schedule` or `event`.
The schedule of this Agent is how often it should check for completed HITs, __NOT__ how often to submit one. To configure how often a new HIT
should be submitted when in `schedule` mode, set `submission_period` to a number of hours.
If created with an event, all HIT fields can contain interpolated values via [JSONPaths](http://goessner.net/articles/JsonPath/) placed between < and > characters.
For example, if the incoming event was a Twitter event, you could make a HITT to rate its sentiment like this:
{
"expected_receive_period_in_days": 2,
"trigger_on": "event",
"hit": {
"max_assignments": 1,
"title": "Sentiment evaluation",
"description": "Please rate the sentiment of this message: '<$.message>'",
"reward": 0.05,
"questions": [
{
"type": "selection",
"key": "sentiment",
"name": "Sentiment",
"required": "true",
"question": "Please select the best sentiment value:",
"selections": [
{ "key": "happy", "text": "Happy" },
{ "key": "sad", "text": "Sad" },
{ "key": "neutral", "text": "Neutral" }
]
},
{
"type": "free_text",
"key": "feedback",
"name": "Have any feedback for us?",
"required": "false",
"question": "Feedback",
"default": "Type here...",
"min_length": "2",
"max_length": "2000"
}
]
}
}
As you can see, you configure the created HIT with the `hit` option. Required fields are `title`, which is the
title of the created HIT, `description`, which is the description of the HIT, and `questions` which is an array of
questions. Questions can be of `type` _selection_ or _free\\_text_. Both types require the `key`, `name`, `required`,
`type`, and `question` configuration options. Additionally, _selection_ requires a `selections` array of options, each of
which contain `key` and `text`. For _free\\_text_, the special configuration options are all optional, and are
`default`, `min_length`, and `max_length`.
If all of the `questions` are of `type` _selection_, you can set `take_majority` to _true_ at the top level to
automatically select the majority vote for each question across all `max_assignments`.
As with most Agents, `expected_receive_period_in_days` is required if `trigger_on` is set to `event`.
