Reply & Supply: Experiment 2 (Synonym Proposal Task) Crowdsourcing Data

These data support the <b>synonymy proposal task</b> (<b>SPT</b>) experiment described in the paper "<i>Reply &amp; Supply: Efficient crowdsourcing when workers do more than answer questions</i>", https://arxiv.org/abs/1611.00954.<br><br>The data consist of two CSV files, one describing the questions built by the crowd as they work, the other recording the responses of workers when presented with questions. A "question id" (`qid`) field links these data. The IDs of Mechanical Turk workers were deidentified. The task interface is described in Fig. 2 of the paper.<br>Three question sampling algorithms were tested in the experiment. These are recorded in the `algorithm`. Note that workers may participate in multiple algorithms, and that `qid` is only unique for a given algorithm (`qid` 1 under the `random` algorithm and `qid` 1 under the `binomial` algorithm are not the same question).
