Inference Web: Portable Explanations for the Web
Knowledge Systems Laboratory
Abstract: Inference Web: Portable Explanations for the Web
The World Wide Web lacks support for explaining information provenance.
When web applications return answers, many users do not know what
information sources were used, when they were updated, how reliable the
source was, what information was looked up versus derived, and if something
was derived, how it was derived.
In this paper we introduce the Inference Web (IW) that addresses the
problems associated with opaque query answers by providing portable,
combinable, and distributed explanations.
The explanations include information concerning where answers came from
and how they were deduced (or retrieved). The IW solution includes:
an extensible web-based registry containing details on information
sources and reasoners, a portable proof specification,
and an explanation browser.
