Allows citizens and business to interact in their own language with public services at local and EU level


The main objective of the CEFAT4Cities Action is to develop a “Smart cities natural language context”, providing multilingual interoperability of the Context Broker DSI and making public “smart city” services multilingual, with pilots in Vienna and Brussels. The language resources that will be created will be committed to the ELRC repository and the following languages will be developed: Dutch, English, French, German, Italian, Slovenian, Croatian and Norwegian.

The main results from the Action will be:

  • A quality-assured workflow for the multilingual extraction and aggregation of ontologies, vocabularies and question-answer pairs, to transform public services websites into semantically enriched ISA2 and OSLO2 compliant services;
  • A curated repository of aggregated and mapped/translated ontologies that allow algorithms to reason on smart city natural language data;
  • A dynamic multilingual repository of questions and answers that can be used to develop multilingual applications such as chatbots and wizards;
  • A semantic interoperability layer for Smart Cities, allowing the Context Broker DSI to integrate with natural language data services, and enabling the development of intelligent eGovernment applications on top of existing public services catalogues.

CEFAT4Cities s co-financed by the Connecting Europe Facility of the European Union under the Grant Agreement no INEA/CEF/ICT/A2019/1926970.
