TASK DEFINITION: In this task, you will be presented with a context from an academic paper and a question based on the context. You have to classify the questions into "Extractive", "Abstractive", or "Yes-no" questions. Extractive questions can be answered by concatenating extracts taken from a context into a summary while answering abstractive questions involves paraphrasing the context using novel sentences. Yes-no question is a question whose expected answer is one of two choices, one that affirms the question and one that denies the question. Typically, the choices are either yes or no.
PROBLEM: In this section, we first describe a baseline method inspired by the "align to segment" of BIBREF12, BIBREF13. We then propose two extensions providing the model with a signal relevant to the segmentation process, so as to move towards a joint learning of segmentation and alignment.
Question: Does the paper report any alignment-only baseline?

SOLUTION: Yes-no

PROBLEM: As a baseline for the RNN models, we apply a uni-directional RNN which predicts the relation after processing the whole sentence.
Question: Which variant of the recurrent neural network do they use?

SOLUTION: Extractive

PROBLEM: Table TABREF20 shows that, on WoZ and DSTC2 datasets, SIM model has the same number of parameters, which is only 23% and 19% of that in GLAD model.
Question: How do they measure model size?

SOLUTION:
Abstractive
