!!! d3web-Core

d3web-Core is main platform API (application programing interface) for the development of knowledge-based applications. 
The platform is available as a collection of Java libraries providing a sophisticated plugin architecture.

A number of components is already included in d3web-Core:
* General representation and persistence of terminological knowledge to represent question (inputs) and solutions (outputs).
* Reasoning engines and persistence for strong problem-solving methods including
** Decision trees
** Scoring rules
** Temporal rules
** DiaFlux models (flowchart knowledge)
** Set-covering models (abductive knowledge)
** Scoring tables
* Libraries for testing knowledge bases

Among others, the following applications are using the d3web-Core:
* KnowWE, a semantic wiki for building knowledge-based applications
* Knowledge Base Book, a generator to create printable documents from knowledge bases
