This preface describes the workshop outline and overview of presented papers at the 18th European Networked Knowledge Organization Systems Workshop (NKOS 2018)7 which was held during the joint DCMI 2018 and TPDL 2018 Conference in Porto, Portugal. This workshop builds on the well-attended NKOS workshops at previous ECDL, TPDL, JCDL conferences (see NKOS website8 for details).
Knowledge Organization Systems (KOS), in the form of classi cation systems, thesauri, lexical databases, ontologies, and taxonomies, play a crucial role in digital information management and applications generally. Carrying semantics in a well-controlled and documented way, Knowledge Organization Systems serve a variety of important functions: tools for representation and indexing of information and documents, knowledge-based support for information searchers, semantic road maps to domains and disciplines, communication tools by providing a conceptual framework, and the conceptual basis for knowledge based systems, e.g. automated classi cation systems. New networked KOS (NKOS) services and applications are emerging, and we have reached a stage where many

KOS standards exist and the integration of linked services is no longer just a
future scenario [
As with the previous workshops, the workshop at TPDL 2018 has three themes as the main focus, together with topical presentations arising from the workshop call for papers9. 1. Alignment/enrichment of metadata to existing KOS Linked Open Data. Recent years have seen an increasing trend to publication of KOS as Linked Data vocabularies. We need discussion of relevant issues and examples of KOS-driven metadata enrichment for a variety of data collection providers, including libraries, archives, museums, publishers, government agencies, international organizations, and also commercial organizations. 2. KOS alignment/interoperability. KOS alignment or terminology mapping has been playing a vital role in NKOS for many years. We continue this theme with discussion of speci c case studies. 3. Automatic KOS-based subject indexing / classi cation /entity-extracting is a classic KOS topic which has seen renewed interest regarding evaluation methodologies. 3
The workshop featured an introduction and three paper sessions. The NKOS organizers have accepted seven regular papers and two invited reports for presentation. All regular papers are included in the CEUR workshop proceedings. In the following we shortly list each workshop paper.

give insights on two recently published papers by the authors in the International
Journal on Digital Libraries [
