WikiKnowledge is proposal for new Wikimedia project to make articles like Wikipedia but in Universal Networking Language format instead of natural languages.
No needs other versions than UNL because must be PHP tools which would validate and generate content in any language. Writing once in UNL would be readable in many languages, UNL is readable for machines and would worlds knowledge base. Would be multilingual Wikipedia and parallel corpus in one. [UNL Wiki page]
Comparing to existing solutions
- Wikipedia: is in human readable format.
