TLDR
The design of Heuristic DENDRAL and its performance on different problems are used for a discussion of the design for a general problem solver that is a variant of the "big switch" theory of generality.Abstract:
Heuristic DENDRAL is a computer program written to solve problems of inductive inference in organic chemistry This paper will use the design of Heuristic DENDRAL and its performance on different problems for a discussion of the following topics: 1 the design for generality; 2 the performance problems attendant upon too much generality; 3 the coupling of expertise to the general problem solving processes; 4 the symbiotic relationship between generality and expertness, and the implications of this symbiosis for the study and design of problem solving systems We conclude the paper with a view of the design for a general problem solver that is a variant of the "big switch" theory of generalityread more

Tutoring rules for guiding a case method dialogue
TL;DR: This paper describes the rule-based formalism used by MYCIN-like programs, and argues that these programs are not sufficient in themselves as teaching tools, and claims that it is desirable to represent teaching expertise explicitly, using a flexible framework that makes it possible to easily modify tutorial strategies and communicate them to other researchers.

Why should machines learn
TL;DR: When I agreed to write this chapter, I thought I could simply expand a paper that I wrote for the Carnegie Symposium on Cognition, but the difficulty with plagiarizing that paper is that it was really about psychology, whereas this book is concerned with machine learning.

Knowledge based engineering: Between AI and CAD. Review of a language based technology to support engineering design
TL;DR: The programming approach, which is a distinctive aspect of state-of-the-art KBE systems, is discussed in detail, to illustrate its effectiveness in capturing and re-using engineering knowledge to automate large portions of the design process.

DENDRAL: a case study of the first expert system for scientific hypothesis formation
TL;DR: The DENDRAL Project was one of the first large-scale programs to embody the strategy of using detailed, task-specific knowledge about a problem domain as a source of heuristics, and to seek generality through automating the acquisition of such knowledge.

Heuristic DENDRAL - A program for generating explanatory hypotheses in organic chemistry.
TL;DR: A computer program has been written which can formulate hypotheses from a given set of scientific data which describe molecular structures which are plausible explanations of the data by heuristic rules.
