Proceedings of the 4th Workshop on the Multilingual Semantic Web 12th Extended Semantic Web Conference (ESWC 2015) Portoroz, Slovenia, 1st June 2015 Introduction The Multilingual Semantic Web workshop series is concerned with research questions on how current Semantic Web infrastructure can be extended to advance the Semantic Web and linked data use and development across language communities around the world. To achieve this goal many important challenges including ontology localisation, cross­lingual question answering, cross­lingual ontology and data matching, representation of lexical information on the Web of Data must be met. Further, a critical mass of language resources as linked data on the Web will enable a new generation of linked data­aware NLP techniques and tools which, in turn, will serve as basis for richer multilingual multimedia Web content analysis. In addressing such research topics, the workshop aims at providing a forum for researchers at the intersection of NLP, multilingual information access, Linked Data and the Semantic Web to exchange ideas on realising the Multilingual Semantic Web. The 4th Workshop on the Multilingual Semantic Web (MSW4) was collocated with the 12th Extended Semantic Web Conference (ESWC 2015) and took place in Portoroz, Slovenia, on 1st June 2015. MSW4 was supported by the EU Project LIDER: “Linked Data as an Enabler of CrossMedia and Multilingual Content Analytics for Enterprises Across Europe”. LIDER aims to provide an ecosystem for the establishment of linguistic linked open data, as well as media resources metadata, for a free and open exploitation of such resources in multilingual, cross­media content analytics across Europe. There were two separate call for papers, one for regular (peer reviewed) papers and another call for position statements. The program committee accepted three submitted manuscripts as long papers and one as short paper, along with one position statement. In addition, an invited paper from the keynote speaker (Armando Stellato, from Tor Vergata University of Rome, Italy) is also included in the proceedings. In addition, the ESWC’15 organisers invited the authors of the two best workshop papers (the most highly rated during the review process) to include their work in a post­proceedings volume “ESWC 2015 Satellite Events” published by Springer.
