Introduction
WelcometotheACL2014StudentResearchWorkshop.
Followingthepreviousyears’ACLStudentResearchWorkshops,thisyearwehavetwodifferentkinds
of papers: research papers and thesis proposals. Thesis proposals are intended for advanced students
who have decided on a thesis topic and wish to get feedback on their proposal and broader ideas for
their continuing work, while research papers can describe completed work or work in progress with
preliminaryresults.
We received 7 thesis proposals and 19 research papers this year. Out of these, we accepted 5 thesis
proposals and 8 research papers leading to an acceptance rate of 71% for thesis proposals and 42%
for research papers. This year’s workshop also offered pre-submission mentoring for student authors
wishing to improve the presentation of their papers prior to submission of the paper for the reviewing
process. 6studentsparticipatedinthispre-submissionmentoringprogramthisyear.

This year’s workshop features three sessions of student paper presentations. All the papers will be
presented at the main conference poster session, giving the opportunity for students to interact and
present their work to a large and diverse audience. We also have a separate oral presentation session
for thesis proposal papers on the first day of the main conference. The third session is another oral
presentationvenuewherestudentauthorsoftheresearchpapersbrieflyadvertisetheirposters. Thisyear,
15 students whose papers were accepted to the ACL main conference were chosen to also present their
work at and be partially funded by SRW. These students’ posters are also advertised during the poster
highlightsession.
