!!! Overview KnowWE is a semantic wiki that provides the possibility to define and maintain ontologies together with strong problem-solving knowledge. Ontologies can be formulated using the RDF(S) or OWL standard: RDF(S) can be included by using the turtle markup, whereas the markup for OWL uses the Manchester syntax. Additionally, KnowWE provides markups for the formalization of the strong problem-solving methods of [d3web-Core]. This includes * Decision trees * Scoring and abstraction rules * Decision tables * Flowchart knowledge with DiaFlux models * Set-covering models KnowWE offers a toolset for the entire knowledge engineering life cycle including * Testing and visually debugging knowledge bases * Refactoring of knowledge bases, e.g., rename question, rename solution, etc. * Evaluation of knowledge bases including the analysis of knowledge bases for anomalies * Continuous integration of knowledge by knowledge builds Since, KnowWE provides a sophisticated plugin architecture, most of the features are included as plugins. New plugins can be easily introduced; see the developer [How-Tos] for more details.
