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: Following recent works, we compare on two widely used datasets, the Penn Treebank (PTB) BIBREF28 as prepared by BIBREF29 and WikiText2 (WT-2) BIBREF20 .

SOLUTION: what data did they use?

PROBLEM: In this approach the similarity between two words is not strictly based on their co–occurrence frequencies, but rather on the frequencies of the other words which occur with both of them (i.e., second order co–occurrences). This approach has been shown to be successful in quantifying semantic relatedness BIBREF12 , BIBREF13 .

SOLUTION: What is a second order co-ocurrence matrix?

PROBLEM: MIMIC-III is a freely available, deidentified database containing electronic health records of patients admitted to an Intensive Care Unit (ICU) at Beth Israel Deaconess Medical Center between 2001 and 2012
