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.

Compared to the in-context-parsing-based system, the combination with exact string matching yields a gain in recall of over 6%, and the combination with inflectional string matching yields an even bigger gain of almost 8%, at precision losses of 0.6% and 0.8%, respectively. 
 Question: What compleentary PIE extraction methods are used to increase reliability further?
exact string matching inflectional string matching
