Lab Meeting, Spring 2017, Week 10

Awe- and Aw-inspiring readings (or just stuff you think deserves a mention)

• You guys, Amazon finally added MTurk support to Boto3 (blog post). If you want current MTurk API, you have to switch to boto3, but it's going to require some code rewriting due to significant changes between boto and boto3. --alw

• Science news post about MTurk pool and psych researchers' dependency on MTurk --alw

What we did over last week

1. Read the documentation for and played around with boto3, including trying to rewrite my getResults.py script. On the plus side, boto3 finally integrates MTurk with the rest of AWS, On the minus side, what you get back is no longer Python types wrapping MTurk XML data structures, but rather Python dictionaries of the keys and values parsed from the XML data. The Answer part of an Assignment actually still comes back as a string of QuestionFormAnswers XML you have to parse yourself. (Hopefully that changes down the road; MTurk support is only 2 weeks old in boto3.)

2. Started writing a proper README for CrowdExp

3. Did a code cleanup of MTurk Utils code

4. Started to really dig into the results conversion code in CrowdExp so it can dump R analyzable results files soon
