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.

Input: Consider Input: We extract 5 Surface and Lexical features, namely sequence length in number of tokens, average word length, type-token ratio, and lexical to tokens ratio (ratio of adjectives, verbs, nouns, and adverbs to tokens). We extracted two features that use a learned representation: Firstly, we get a sentence embedding feature that is built by averaging the word embeddings of an input sentence. Secondly, we extract a fastText representation using the fastText library with the same parameters as reported in Joulin et al. joulin2016bag. 
 Question: Do they differentiate insights where they are dealing with learned or engineered representations?

Output: Yes-no


Input: Consider Input: For comparison, we also report the performance of the error detection system by Rei2016, trained using the same FCE dataset. 
 Question: What was the baseline used?

Output: Extractive


Input: Consider Input: The result on original WikiQA indicates that all three transfer learning methods not only do not improve the results but also hurt the F1-score. These are because other datasets could not add new information to the original dataset or they apparently add some redundant information which are dissimilar to the target dataset. 
 Question: Do transferring hurt the performance is the corpora are not related?


Output: Yes-no
