  In this paper, we present our work on the BioASQ pipeline. The goal is to
answer four types of questions: summary, yes/no, factoids, and list. Our goal
is to empirically evaluate different modules involved: the feature extractor
and the sentence selection block. We used our pipeline to test the
effectiveness of each module for all kinds of question types and perform error
analysis. We defined metrics that are useful for future research related to the
BioASQ pipeline critical to improve the performance of the training pipeline.
