From Inference Web
The Inference Web is a Semantic Web based knowledge provenance infrastructure that supports interoperable explanations of sources, assumptions, learned information, and answers as an enabler for trust.
- Provenance - if users (humans and agents) are to use and integrate data from unknown, uncertain, or multiple sources, they need provenance metadata for evaluation
- Interoperability - more systems are using varied sources and multiple information manipulation engines, thus increasing interoperability requirements
- Explanation/Justification - if information has been manipulated (i.e., by sound deduction or by heuristic processes), information manipulation trace information should be available
- Trust - if some sources are more trustworthy than others, trust ratings are desired
The Inference Web consists of two important components:
- Proof Markup Language (PML) Ontology - Semantic Web based representation for exchanging explanations including
- provenance information - annotating the sources of knowledge
- justification information - annotating the steps for deriving the conclusions or executing workflows
- trust information - annotating trustworthiness assertions about knowledge and sources
- IW Toolkit - Web-based and standalone tools that facilitate human users to browse, debug, explain, and abstract the knowledge encoded in PML.
