When web applications return answers, many users do not know what information sources were used, when they were updated, how reliable the source was, or what information was looked up versus derived. The Web also lacks support for explaining reasoning paths used to derive or retrieve answers. The Inference Web (IW) aims to take opaque query answers and make the answers more transparent by providing explanations. The explanations include information concerning where answers came from and how they were derived (or retrieved). This chapter describes the IW support for explanations on question answering (QA) environments. A characterization of explanation strategies on QA environments is presented. One usage of the Inference Web infrastructure, and in particular of the browser, explainer, and portable proof specification for supporting multiple explanation strategies in the KSL Wine Agent is described in the chapter. Also, a generic architecture for a QA environment incorporating the Inference Web for explaining answers is presented. incollection New Directions in Question Answering mcguinness2004trusting 275-286 Trusting Answers from Web Applications 2004 Year Title Computer science Tag Inference web Relation AAAI/MIT Press Publisher Media:Mcguinness2004trusting.pdf Paper Pages November Month Key Mark T.
