#### The power of physical representations

(AAAI Press, 1989)

Commonsense reasoning about the physical world, as exemplified by 'Iron sinks in water' or 'If a ball is dropped it gains speed,' will be indispensable in future programs. We argue that to make such predictions (namely, ...

#### Ray representation for k-trees

(Elsevier, 1989)

k-trees have established themselves as useful data structures in pattern recognition. A fundamental operation regarding k-trees is the construction of a k-tree. We present a method to store an object as a set of rays and ...

#### Representing objects as rays, or how to pile up an octree?

(Elsevier, 1989)

Quadtrees, octrees, and in general k-trees have established themselves as useful hierarchical data structures in computer graphics, image processing, and solid modeling. A fundamental operation in a system based on k-trees ...

#### Sweeping with all graphical ingredients in a topological picturebook

(Elsevier, 1992)

Sweeping is a powerful method to generate 3-D shapes in geometric modeling. In this paper we formulate a general matrix to give a mathematical definition of twisted-profiled sweep objects as a discrete approximation. While ...

#### On the correct determination of rotational angles for twisted-profiled sweep objects

(1994)

In the context of the paper of V. Akman and A. Arslan, "Sweeping with All Graphical Ingredients in a Topological Picturebook" [Computers & Graphics, Vol. 16(3), pp. 273-281, 1992], a new construction of the rotational ...

#### Commonsense aspects of buying and selling

(Taylor & Francis Inc., 1996)

We describe an experimental approach toward implementing a commonsense "microtheory" for buying and selling. Our prototype system characterizes how intelligent agents hold items and money, how they buy and sell items, and ...

#### Issues in commonsense set theory

(Springer/Kluwer Academic Publishers, 1994)

The success of set theory as a foundation for mathematics inspires its use in artificial intelligence, particularly in commonsense reasoning. In this survey, we briefly review classical set theory from an AI perspective, ...

#### Hypersolver: a graphical tool for commonsense set theory

(Elsevier, 1995)

This paper investigates an alternative set theory (due to Aczel) called the Hyperset Theory. Aczel uses a graphical representation for sets and thereby allows the representation of non-well-founded sets. A program, called ...

#### V. Lifschitz, ed., formalizing common sense: papers by John McCarthy

(Elsevier BV, 1995)

A review is presented of Lifschitz's collection of seventeen papers written by McCarthy on the subject of common sense. The book opens with a fine overview of McCarthy's research in artificial intelligence (AI). Lifschitz ...
