In this task, you will be presented with a context from an academic paper and a question separated with a 
. You have to answer the question based on the context.

Example Input: Results on all sets show an important difference between precision and recall, precision being significantly higher than recall. There is also a significant difference between the results obtained on development and test set (F1 = 89.60, F1 = 87.82) and the results on the supplemental test set (F1 = 71.49). The time difference between the supplemental test set and the development and test set (the headlines from the the supplemental test set being from a different time period to the training set) can probably explain these differences. 
 Question: What is the performance of the CRF model on the task described?
Example Output: the results obtained on development and test set (F1 = 89.60, F1 = 87.82) and the results on the supplemental test set (F1 = 71.49)

Example Input: They can answer each question with either `yes', `rather yes', `rather no', or `no'. They can supplement each answer with a comment of at most 500 characters. 
 Question: What annotations are present in dataset?
Example Output: answer each question with either `yes', `rather yes', `rather no', or `no'. can supplement each answer with a comment of at most 500 characters

Example Input: In order to compare with the previous methods, we evaluate our model on AIDA-B and other datasets.  AIDA-CoNLL BIBREF14 is annotated on Reuters news articles. It contains training (AIDA-Train), validation (AIDA-A) and test (AIDA-B) sets.

ACE2004 BIBREF15 is a subset of the ACE2004 Coreference documents.

MSNBC BIBREF16 contains top two stories in the ten news categories(Politics, Business, Sports etc.)

AQUAINT BIBREF17 is a news corpus from the Xinhua News Service, the New York Times, and the Associated Press.

WNED-CWEB BIBREF18 is randomly picked from the FACC1 annotated ClueWeb 2012 dataset.

WNED-WIKI BIBREF18 is crawled from Wikipedia pages with its original hyperlink annotation. 
 Question: What datasets used for evaluation?
Example Output:
