Zusammenfassung:
Recent neural IR models have demonstrated deep learning's utility in ad-hoc
information retrieval. However, deep models have a reputation for being black
boxes, and the roles of a neural IR model's components may not be obvious at
first glance. In this work, we attempt to shed light on the inner workings of a
recently proposed neural IR model, namely the PACRR model, by visualizing the
output of intermediate layers and by investigating the relationship between
intermediate weights and the ultimate relevance score produced. We highlight
several insights, hoping that such insights will be generally applicable.
