Home UNL Society What it is?

A new UNL Explorer has been developed and is provided at www.undl.org/unlexp/ and www.unl.undl.org/unlexp/ by the UNL Center.



The UNL Explorer is a UNL-based Multilingual Intelligent Information and Knowledge Management System.



The UNL Explorer provides users with an integrated environment that users can search for and edit knowledge and information based on UNL.



Using the UNL Explorer, search for information of UNL Encyclopedia can be made by content, keyword or keyconcept search, or though navigation of the UW System of the UNL Ontology



The UNL Explorer has the following characteristics:


Semantic Co-occurrence Relation Search

whether a relation between two UWs is true or not, what UWs can have a relation with another UW, or what relations are possible between two UWs can be verified based on the UNL Ontology.




UNL-based Semantic Network Search

Content search is carried out based on UNL Expressions.




Intensional Definition-based Inference

every UW is given an intentional definition to specify its all the essential properties. the definition is used in inference about all concepts it related.




Multilingual Information Processability

the UNL Explorer allows users to search for information described in whatever language using their native languages, or to provide or edit information using their native languages.




UNL Graphical Editability

A graphical editor of UNL Expressions works together with the UNL Explorer.

What it is?

The UNL Centre created the UNL SOCIETY as an informal collaborating and support group for the development and testing the UNL. Membership includes individuals and organizations, including businesses interested in UNL development and deployment. They enter the association by signing an agreement , by which they adhere to a very single set of rules which essentially specifies the benefits and obligations, as follows:
  • Benefits
    The member has acces to the UNL resources free of charge, and can use them for R&D or experiments, tests, research and other non-commercial activities. They will be the first to be provided with the new developments of the UNL in terms of language, system and tools. The will have privilege access information-sharing on the UNL general and on experimental test. For details please visit: http://www.undl.org/uds/
  • Obligations
    Respect the property rights of the UNL language, system and tools provided by the UNL Centre, and refrain from commercial activities of products generated from or in conjunction with the UNL, without prior consent from UNL Centre; if opportunities for commercial activities emerge, a separate specific agreement shall be signed between the UNL Centre and the Society member, in which the property rights shall be clearly defined and royalties or other advantages properly stipulated.

The UNL Society Members are encouraged to undertake research and studies on and for the development or improvement of the UNL. When published, reference to the UNL source shall be made.

It is anticipated that as UNL gain strength, the UNL Society will naturally evolve into a more formal and structured autonomous scientific and technological society, with its own statute, form of governance, and programme of activities.
