So here is the multiple choice question (MCQ) datasets that I crawled for my course project: Answering Multiple-choice Questions Using Machine Learning Techniques. Download
Dataset Descriptions: These data are mainly harvest by some exam MCQ websites and the available testbank for textbooks. Notice that the MCQs with not enough data quality is removed. We delete the questions with less than three words. Also, the question that is based on a graph, a table, or other references rather than the question itself is deleted.
Here is my memo for some network dataset resources that are available online.
SNAP dataset, Stanford Large Network Dataset Collection A huge dataset collection on all kind of graph such Facebook Relationship connection graph, AS topology graph, citation graph, twitter graph and so on, their SNAP-python graph lib is also powerful and fast. KONECT, The Koblenz Network Collection The other big collection site for graph and network dataset.
