The Figure 4 in paper described question process.I regard the entity retrieval as obtaining the entity by ner tools from question text.But there is no entity named "Ethiopia" in the question text.It seems like an answer, and I check the code in the coressponding part of question process, It may valid my thought.So, how do i understand this part of question process in paper?
