Introduction
WelcometotheACL2018StudentResearchWorkshop!
The ACL 2018 Student Research Workshop (SRW) is a forum for student researchers in computational
linguistics and natural language processing. The workshop provides a unique opportunity for student
participants to present their work and receive valuable feedback from the international research
communityaswellasfromselectedmentors.
Followingthetraditionofthepreviousyears’studentresearchworkshops,wehavetwotracks: research
papersandresearchproposals. TheresearchpapertrackisavenueforPh.D.students,Mastersstudents,
and advanced undergraduates to describe completed work or work-in-progress along with preliminary
results. TheresearchproposaltrackisofferedforadvancedMastersandPh.D.studentswhohavedecided
on a thesis topic and are interested in feedback on their proposal and ideas about future directions for
theirwork.
We received 66 submissions in total: 12 research proposals and 54 research papers. We accepted 26
papers,foranacceptancerateof39%. Afterwithdrawals,22papersareappearingintheseproceedings,
including 6 research proposals and 16 research papers. All of the accepted papers will be presented as
postersinlunchtimesessionsasapartofthemainconference,splitacrosstwodays(July17thand18th).
Mentoring is at the heart of the SRW. In keeping with previous years, students had the opportunity
to participate in a pre-submission mentoring program prior to the submission deadline. This program
offered students a chance to receive comments from an experienced researcher, in order to improve the
qualityofthewritingandpresentationbeforemakingtheirsubmission. Elevenauthorsparticipatedinthe

We are deeply grateful to our sponsors whose support will enable a number of students to attend the
conference, including the Don and Betty Walker Scholarship Fund, Roam Analytics, Google, and the
National Science Foundation under award No. 1827830. We would also like to thank our program
committee members for their careful reviews of each paper, and all of our mentors for donating their
timetoprovidefeedbacktoourstudentauthors.
Thank you to our faculty advisors Marie-Catherine de Marneffe, Wanxiang Che, and Malvina Nissim
for their essential advice and guidance, and to the members of the ACL 2018 organizing committee, in
particularClaireCardie,YusukeMiyao,andPriscillaRasmussenfortheirhelpfulsupport. Finally,thank
youtoourstudentparticipants!
