In this task, you will be presented with a context from an academic paper and a question separated with a 
. You have to answer the question based on the context.

[EX Q]: We recruited 100 crowdworkers on Amazon Mechanical Turk (AMT) and measured completion times and accuracies for typing randomly sampled sentences from the Yelp corpus.  
 Question: What user variations have been tested?
[EX A]: completion times and accuracies 

[EX Q]: The ratio of correct `translations' (matches) was used as an evaluation measure. 
 Question: What evaluation metric do they use?
[EX A]: Accuracy

[EX Q]: We can identify three main cases for which the model produces an error:

the correct class can be directly inferred from the text content easily, even without background knowledge

the correct class can be inferred from the text content, given that event-specific knowledge is provided

the correct class can be inferred from the text content if the text is interpreted correctly 
 Question: What type of errors do the classifiers use?
[EX A]:
correct class can be directly inferred from the text content easily, even without background knowledge correct class can be inferred from the text content, given that event-specific knowledge is provided orrect class can be inferred from the text content if the text is interpreted correctly
