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: Secondly, texts go through a cascade of annotation tools, enriching it with the following information:

Morphosyntactic interpretations (sets of tags), using Morfeusz 0.82 BIBREF25 ,

Tagging (selection of the most probable interpretation), using a transformation-based learning tagger, PANTERA 0.9.1 BIBREF26 ,

Syntactic groups (possibly nested) with syntactic and semantic heads, using a rule-based shallow parser Spejd 1.3.7 BIBREF27 with a Polish grammar, including improved version of modifications by BIBREF28 , enabling lemmatisation of nominal syntactic groups,

Named entities, using two available tools: NERF 0.1 BIBREF29 and Liner2 2.3 BIBREF30 .

 
 Question: How is the data in RAFAEL labelled?

Output: Abstractive


Input: Consider Input: The data stems from a joint ADAPT-Microsoft project.  
 Question: what dataset was used?

Output: Abstractive


Input: Consider Input: The seed lexicon consists of positive and negative predicates. If the predicate of an extracted event is in the seed lexicon and does not involve complex phenomena like negation, we assign the corresponding polarity score ($+1$ for positive events and $-1$ for negative events) to the event. It is a  
 Question: What is the seed lexicon?


Output: Abstractive
