 omparative questions and identifying important constituents of comparative

 er stance detection of answers towards these comparison options. Following
  that\, he will discuss argument retrieval\, which represents a specific c
 ase within the broader domain of information retrieval.\nIn the final part

 oncerning answering comparative questions with arguments. In particular\, 
 he focused on question understanding\, argument retrieval\, argument quali
 ty prediction\, and stance detection. His current research focuses on a ge
