Task and Situation Structures for Service Agent Planning
  Everyday tasks are characterized by their varieties and variations, and
frequently are not clearly specified to service agents. This paper presents a
comprehensive approach to enable a service agent to deal with everyday tasks in
open, uncontrolled environments. We introduce a generic structure for
representing tasks, and another structure for representing situations. Based on
the two newly introduced structures, we present a methodology of situation
handling that avoids hard-coding domain rules while improving the scalability
of real-world task planning systems.
