Inference Web: Enabling Accountable Web Applications

Printer-friendly version

Abstract:

To trust answers from Web applications, users need access to provenance metadata: i.e., who, what, when, where, how info.

Inference Web (IW) provides infrastructure for representing and computing provenance on the Web and for the Web

Inference Web Solution:
  • Interoperable Representation
    • to support different languages
    • to transcend system boundaries
  • Extensible Infrastructure
    • provides basic data services (search, validation, etc.)
    • supports end-user explanation
  • Low Adoption Cost
    • for data and ontology engineers
    • for application developers
    • for end users

Description: 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.

Description: Web Science is the study of the World Wide Web and its impact on both society and technology, positioning the Web as an object of scientific study unto itself. Web Science recognizes the Web as a transformational, disruptive technology; its practitioners study the Web, its components, facets and characteristics. Ultimately, Web Science is about understanding the Web and anticipating how it might evolve in the future.
