Gerhard Fischer, Institut fuer Informatik Universitaet Stuttgart, West-Germany It is our firm belief that solving problems in the domain of computational linguistics (CL) can provide a set of metaphors or powerful ideas which are of great importance to many fields. We have taught several experimental classes to students from high …...

This paper discusses an approach to incremental learning in natural language processing. The technique of projecting and integrating semantic constraints to learn word definitions is analyzed as Implemented in the POLITICS system. Extensions and improvements of this technique are developed. The problem of generalizing existing word meanings and understanding metaphorical …...

Two styles of performing inference in semantic networks are presented and com- pared. Path-based inference allows an arc or a path of arcs between two given nodes to be inferred from the existence of an- other specified path between the same two nodes. Path-based inference rules may be written using …...

This paper surveys a number of kinds of default reasoning in Artificial Intelligence, spec- ifically, default assignments to variables, the closed world assumption, the frame default for causal worlds, exceptions as defaults, and negation in Artificial Intelligence programming languages. Some of these defaults provide clear representa- tional and computational advantanges …...

The paper outlines a computational theory of human plausible reasoning constructed from analysis of people's answers to everyday questions. Like logic, the theory is expressed in a content-independent formalism. Unlike logic, the theory specifies how different information in memory affects the certainty of the conclusions drawn. The theory consists of …...

A language comprehension program using "frames", "scripts", etc. must be able to decide which frames are appropriate to the text. Often there will be explicit indication ("Fred was playing tennis" suggests the TENNIS frame) but it is not always so easy.("The woman waved while the man on the stage sawed …...

It is argued that without a connection to the real world via perception, a language system can- not know what it is talking about. Similarly, a perceptual system must have ways of expressing its outputs via a language (spoken, written, gestural or other). The relationship between perception and language is …...

Once a_.nn ~ is introduced into a discourse, the form of subsequent references to it are strongly governed by convention. This paper discusses how those conventions can be represented for use by a generation facility. A multistage representation is used, allowing decisions to be made when and where the information …...

A sentence (or other portion of discourse) is taken to evoke in the listener a meaning complex, here called a "cognitive representation". The lex- ical elements of the sentence, to simplify, by and large specify the content of the cognitive represen- tation, while the grammatical elements specify its structure. Thus, …...
