Soar: an architecture for general intelligence

TL;DR: SOAR, an implemented proposal for a foundation for a system capable of general intelligent behavior, is presented and its organizational principles, the system as currently implemented, and demonstrations of its capabilities are described.

Instructional Design Models for Well-Structured and Ill-Structured Problem-Solving Learning Outcomes

TL;DR: The model for solving well-structured problems is based on information processing theories of learning, while the model for solved ill-structuring problems relies on an emerging theory of ill- Structured problem solving and on constructivist and situated cognition approaches to learning

The Hearsay-II Speech-Understanding System: Integrating Knowledge to Resolve Uncertainty

TL;DR: The characteristics of the speech problem in particular, the special kinds of problem-solving uncertainty in that domain, the structure of the Hearsay-II system developed to cope with that uncertainty, and the relationship between Hearsey-II's structure and those of other speech-understanding systems are discussed.

A Cognitive Model of Planning

TL;DR: A cognitive model of the planning process that generalizes the theoretical architecture of the Hearsay-II system and illustrates its assumptions with a “thinking aloud” protocol is presented and the performance of a computer simulation of the model is described.

Planning in a hierarchy of abstraction spaces

TL;DR: Examples of the ABSTRIPS system's performance are presented that demonstrate the significant increases in problem-solving power that this approach provides, and some further implications of the hierarchical planning approach are explored.
