Preface
We are living in a fascinating period, when the applications of natural language pro-
cessing (NLP) are going mainstream. The maturity of the field has reached a stage in
which its solidity can be witnessed in the adoption and uptake of its technologies
outside the core NLP academic community. The success and visibility of software
systemssuchasIBMWatson,Siri,andGoogleKnowledgegraphareincentivizingthe
increase of interest in the field and the adoption of NLP in diverse areas.
The past two decades in which NLDB has been active were fundamental for the
establishmentofthefoundationsandthefurthermaturationofthisfieldandNLDBcan
claimtheshareofitscontributions.Duringthistime,NLDBhasbeenoneofthemain
conferences for applications in NLP, in which researchers could find a sweet spot
between rigorous scientific contributions and openness to new ideas and perspectives.
Another notable characteristic that has been consistently present at NLDB is multidis-
ciplinarity:NLDBhaswelcomedcontributionsfromapplicationsofNLPintodifferent
areas,andhashelpedinbridging NLPtodifferent communitiesandapplication fields.
Thisyear’sNLDBfeaturedaspecialtrackonnaturallanguageanditsconnectionto
semantic and cognitive computing. Semantic computing aims at connecting the user’s
informationneedwiththemeaningofcontentinamultidisciplinaryfashion.Cognitive
computing systems naturally interact with people and learn over time.
TheNLDB2015programspannedawiderangeoftopicsthatallrevolvearoundthe
useofnaturallanguagetoaccessinformation.Threeinvitedspeakerscoveredtopicsas
diverse as distributional semantics, computational humanities, and linked open data.
Sessions comprised the following topics: unsupervised and semi-supervised machine
learning,information extraction, event extraction and named entityrecognition,multi-
lingual alignment and translation, sentiment detection and user-generated content pro-
cessing, indexing and the lexicon, query processing, question answering, speech
processing,anddialogsystems.Last,butnotleast,thespecialsessiononsemanticand
cognitivecomputing attracted position papers and featureda sponsoredtalk byIBM.

thank the Program Committee and reviewers for their hard work and dedication. We
would also like to thank the invited speakers for their inspiring contributions to the
program.
NLDB 2015 was held in the picturesque town of Passau. Dating back to Roman
times,PassauislocatedattheGerman-Austrianborderanditisnotableforbeingatthe
convergenceofthreerivers(theDanube,theInn,andtheIlz).Itslocationattheheartof
Europe and its proximity to different borders made Passau a natural confluence for
different cultures and influences, a fact that is embodied in its architecture that har-
moniouslyblendsGerman,Austrian,andItalianstyles.Despiteitsopenness,Passauis

TheconferencewasgenerouslysupportedfinanciallybytheInsightCentreforData
Analytics, the SSIX EU Project, IBM (Platinum Sponsors), by the University of
Passau, which hosted the conference, and by 3rdParty (Silver Sponsor). Adamantios

for the organization of the conference, supporting the sponsorship, and in the local
coordination of the event.

members, and organizers for the past editions of NLDB.
