TASK DEFINITION: In this task, you will be presented with a context from an academic paper and you have to write an answerable question based on the context. Your questions can be extractive, abstractive, or yes-no questions.
PROBLEM: To help the human representative quickly determine the cause of the escalation, we generate a visualization of the user's turns using the attention weights to highlight the turns influential in the escalation decision.

SOLUTION: Do they explain model predictions solely on attention weights?

PROBLEM: Validated transcripts were sent to professional translators. In order to control the quality of the professional translations, we applied various sanity checks to the translations BIBREF11. We also sanity check the overlaps of train, development and test sets in terms of transcripts and voice clips (via MD5 file hashing), and confirm they are totally disjoint.

SOLUTION: How is the quality of the data empirically evaluated? 

PROBLEM: We started from an initial corpus that did not have revisions, and kept adding new documents and revising existing documents. The revision operations we used were deletion, addition and replacement of words, sentences, paragraphs, section names and document titles. The addition of words, ..., section names, and new documents were pulled from the Wikipedia abstracts. We generated six data sets using different random seeds, and each data set contained six corpora (Corpus 0 - 5).

SOLUTION:
What are simulated datasets collected?
