In an unprecedented move among competitors, all daily newspaper publishers from the Netherlands joined together with the goal of creating a next generation semantic tagging platform.  Ontotext and our partners Dayon were tasked with developing this system, which included the sourcing of third-party data sets and the engineering of text analytics systems to improve the efficiency of content generation.


Siemens and their partner Publicis set out to build a semantic tagging framework, and sought Ontotext’s vast media industry experience in this area.  The daunting goal for these two organizations was to change the way journalists and copywriters create broader content.

Utilizing Ontotext’s technologies and experience, the project was big success, resulting in better content.  Now, every paragraph submitted to the system through the WYSIWYG editor generates a query which returns relevant content from the Siemens’ content silos. The result is stories that provide more insight and a deeper, more analytical viewpoint.


A leading international business-to-business publisher, focused primarily on international finance, Euromoney chose Ontotext to develop a unified semantic publishing platform to bridge the information gaps between over 100 business units.  As a result, the business units will not only be able to more quickly create content, but, having access to all historical content within all groups, will make for better, more enriched content.

UK legislation carries most types of legislation and their accompanying explanatory documents. It has about 2 million visitors monthly. The Stationery Office (TSO) developed, and now hosts and manages, the site for The National Archives (TNA). The programme to implement the site required content migration from various sources and resulted into a massive 6.5 million documents that are available on the website and this is growing daily. For the first time the government can demonstrate precisely how an Act would look if an Amending Bill is passed. GraphDB™ (formerly OWLIM) is being used to support a new, sophisticated, editorial and workflow management system that underpins GraphDB™ was chosen because of its scalability, support for transactional processes and SPARQL 1.1 support.


The Food and Agriculture Organization of the United Nations (FAO) chose GraphDB™ as an RDF Database for their information portal. The portal is an innovative, web-based platform that brings together statistics, maps and pictures (and soon documents) on nutrition, food and agriculture from throughout FAO, providing easy access, a powerful search engine and data visualizations all in one convenient location.

Natural Resources Canada

Natural Resources Canada (NRCan) seeks to enhance the responsible development and use of Canada’s natural resources. Through the use of GraphDB™ NRCan plans to move their RDBMS static file based mediation database, which allows querying heterogeneous databases (schematic and semantic), to a RDF store that provides reasoning. Speed is the primary consideration in the project, due to the fact that the translation involves a significant amount of vocabulary conversion.


LODAC (Linked Open Data in Academia) was created by Japan’s National Institute of Informatics to aggregate information across multiple Japanese resources as Linked Open Data. Many Japanese museums have digitized their museum collections and this data is scraped by LODAC and mapped to a RDF in CIDOC CRM. Related artists and artworks from different museum collections are associated then accessed through an integrated data views. The result is LODAC-Museum, which includes web presentation, natural language search and a SPARQL endpoint.  See more about this solution in LODAC Museum: Linked Open Data for Academic Resources.

British Museum

An Ontotext-led consortium won The British Museum tender for development of the ResearchSpace project funded by the Andrew W. Mellon Foundation. This project aims to support collaborative web-based research, information sharing and web publishing for the cultural heritage scholarly community.

The system will be based on the CIDOC CRM ontology, which supports very generic description of cultural artefacts, related events (e.g. creation, acquisition, curation, conservation), annotations, research discourse.

Conservation Space

ConservationSpace is another project funded by the Andrew W. Mellon Foundation that is run by the National Gallery of Art, Washington D.C. and seven other institutional partners. The project will develop an open-source system to address a core need of the conservation community for a shared solution for documentation management.

Sirma ITT and Ontotext won the international tender for the Build phase of the project, making this the second Mellon project being developed by Ontotext.


The British Museum (BM) and Yale Center for British Art (YCBA) have selected GraphDB™ (formerly OWLIM) for their semantic repository.  GraphDB™ was chosen due to its high performance in both data loading and querying, strict standards compliance, OWL reasoning, and rule inferencing that are useful for CRM and complex search. An added benefit is that GraphDB™ supports the new W3C standard SPARQL 1.1 Federated Query that allows a user to interrogate several semantic repositories at once. Federation can help research communities and projects to collaborate on a certain topic, even when the relevant works and data are spread out through different collections.


In September 2012, Europeana published its API allowing free access to all Europeana data – more than 20 million cultural heritage objects from all of Europe.  A month later, the RDF dataset in EDM (Europeana Data Model) format was made available to the public. Ontotext was invited to host the Europeana SPARQL endpoint. Europeana SPARQL endpoint is a reason-able view of the web of data, loaded in GraphDB™ semantic repository with OWL-Horst inference, using Forest framework as a front end. It comprises 993 million explicit statements, and close to 4 billion retrievable statements.  It is accessible at, and


Europeana Creative is an European CIP PSP project that started in Feb 2013. It will allow Europeana to facilitate the creative re-use of cultural heritage metadata and content. It will create five pilot applications in the thematic areas of History Education, Natural History Education, Tourism, Social Networks, and Design.

The Polish Digital National Museum aggregates artifacts from cultural institutions in the Digital Libraries Federation PIONIER Network: over 70 contributing institutions including universities, libraries, museums, archives, research. The Poznan Supercomputing and Networking Center transforms all provided data to RDF using common ontologies such as CIDOC CRM, and relevant vocabularies related to Europeana. The aggregated collection contains 681 thousand objects and is published with specially developed software (dMuseion). GraphDB™ is used as the RDF repository for this project.


The Gothenburg City Museum provided close to 9K museum objects from two collections to build a use case within the MOLTO FP7 project.  The goal is a knowledge representation infrastructure that allows for RDF querying and the presentation of RDF results in natural language. The knowledge representation infrastructure is based on Ontotext’s approach, known as “reason-able views of the web of data.” Museum data is modeled according to CIDOC CRM, integrated with the DBpedia and GeoNames datasets, and upper-level ontologies such as PROTON that facilitate the integration. The museum reason-able view contains 305M triples, and is accessible via a SPARQL endpoint.
