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
