Since its establishment in 2012, the Linked Data in Linguistics (LDL) workshop series has become the major forum for presenting, discussing and disseminating technologies, vocabularies, resources and experiences regarding the application of Semantic Web standards and the Linked Open Data paradigm to language resources in order to facilitate their visibility, accessibility, interoperability, reusability, enrichment, combined evaluation and integration. The LDL workshop series is organized by the Open Linguistics Working Group of the Open Knowledge Foundation, and has contributed greatly to the emergence and growth of the Linguistic Linked Open Data (LLOD) cloud. LDL workshops contribute to the discussion, dissemination and establishment of community standards that drive this development, most notably the Lemon/OntoLex model for lexical resources, as well as standards for other types of language resources still under development. Building on our earlier success in creating and linking language resources, LDL-2018 will focus on Linguistic Data Science, i.e., research methodologies and applications building on Linguistic Linked Open Data and the existing technology and resource stack for linguistics, natural language processing and digital humanities. LDL-2018 builds on the success of the workshop series, incl. two appearances at LREC (2014, 2016), where we attracted a large number of interested participants. As of 2016, LDL workshops alternate with our stand-alone conference on Language, Data and Knowledge (LDK). LDK-2017 was held in Galway, Ireland, as a 3-day event with 150 registrants and several satellite workshops. Continuing the LDL workshop series together with LDK is important in order to facilitate dissemination within and to receive input from the language resource community, and LREC is the obvious host conference for this purpose. LDL-2018 will be supported by the ELEXIS project on an European Lexicographic Infrastructure.
