EKT Information System for Semantic Vocabularies is a system where EKT and other authorized institutions create their own semantic vocabularies. The vocabularies are freely available as Open Linked Data. The portal allows the visitor to access vocabularies and terms both by hierarchical navigation and by using the search engine. The search engine covers not only terms registered in the system but also a series of public external standard vocabularies. Semantics.gr also provides a tool for mapping metadata field values to vocabulary terms which can be used by repositories and aggregators to enrich and homogenize their content.
EKT enriches the metadata aggregated in SearchCulture.gr with links to established vocabularies and homogenises them through the enrichment tool of semantics.gr. The aggregated content is enriched and homogenized with respect to types and chronological information which subsequently allowed the development of advanced multilingual search and browsing features, including hierarchical navigation on types and historical periods, searching and faceting on type, time span and historical period, a tag cloud of types and an interactive timeline.
