Semantic technologies, ontology engineering, GraphDB and research are provided by Ontotext.

Cloud-based solutions are based on the Sirma Enterprise Platform with its knowledge models, functional modules and cognitive core services.


Current European Research Projects in the cultural heritage domain that we participate in:

  • MOLTO – Multilingual Online Translation – developing tools for translating texts between multiple languages in real time with high quality.
  • RENDER – Reflecting Knowledge Diversity – developing methods, techniques, software and data sets that will leverage diversity as a crucial source of innovation and creativity. Techniques developed together with Google for relating news articles to Linked Open Data, and for clustering entities, can be used profitably on CH data.
  • EUCLID – Educational Curriculum for the usage of Linked Data – professional training curriculum for data practitioners aiming to use Linked Data in their daily work. Strongly relevant to cultural heritage metadata specialists and other experts focusing on Linked Open Data.
  • AnnoMarket – Cloud-Based Text Annotation Marketplace – aims to revolutionize the text annotation market, by delivering an affordable, open marketplace for pay-as-you-go, cloud-based extraction resources and services, in multiple languages. Multilingual semantic entity extraction from cultural heritage text (e.g. museum object descriptions) is an important and largely unsolved problem.
  • LDBC – Linked Data Benchmark Council – aims to establish a global, vendor-neutral, non-profit organization for publishing and auditing benchmark results for graph and RDF databases. Cultural heritage institutions that want to use semantic repositories require benchmark information, and can provide important cultural heritage data sets, use cases and feedback.
  • Europeana Creative – re-use of cultural heritage metadata and content by the
    creative industries. This project provides a crucial contribution to improving the usefulness and kick-starting the professional use of Europeana data.
