To assess the current state of the art and foster the systematic comparison of contri- butions to the Semantic Web community, open challenges are now a key scientific event of the Semantic Web conferences. After last year’s success, we organized the second edition of the“SemanticWebEvaluation Challenge” asan official track ofthe ESWC2015conference(heldinPortorož,Slovenia,fromMay31toJune42015),one of the most important international scientific events for the Semantic Web research community.Thepurposeofchallengesistoshowcasethematurityofthestateoftheart in tasks common to the Semantic Web community and adjacent academic communi- ties, in a controlled setting of rigorous evaluation. In particular, this second edition focusedonfourareas:OpenKnowledgeExtraction(OKE-2015),SemanticPublishing (SemPub2015), Concept-Level Sentiment Analysis (CLSA-2015), and Schema- AgnosticQueriesoverLinkedData(SAQ-2015).Atotalof19teamswereacceptedto compete in different challenges (four participants for OKE-2015, nine for Sem- Pub2015, four for CLSA-2015, and two for SAQ-2015). The event attracted several attendees, many of whom came to the conference specifically to attend the challenge, indicating that Semantic Web Evaluation Challenges were much welcomed by the community and brought added value to the conference. This book includes the descriptions of all methods and tools that competed at “SemanticWebEvaluationChallenge2015,”togetherwithadetaileddescriptionofthe tasks, and evaluation procedures and datasets, offering to the community a snapshot oftheadvancementinthoseareasatthatmomentintime,andmaterialforreplications ofresults.Theeditorshavedividedthebookcontentintofourchapters,eachdedicated to one area (and challenge). The first chapter refers to “Open Knowledge Extraction,” the second chapter to “Semantic Publishing,” the third to “Concept-Level Sentiment Analysis,”andthefourthto“Schema-AnosticQueriesoverLinkedData.”Eachchapter includes an introductory section by the Challenge Chairs providing a detailed description of the challenge tasks, the evaluation procedure, and associated datasets. We would like to thank the challenges chairs, who worked hard during the orga- nizationofthe2015editionoftheSemanticWebChallenges.Thankstotheirwork,we experiencedasuccessfulandinspiringscientificevent,andwearenowabletodeliver this book to the community.
