The General Motors Variation-Reduction Adviser is a knowledge system built on case-based reasoning principles that is currently in use in a dozen General Motors Assembly Centers. This paper reviews the overall characteristics of the system and then focuses on various AI elements critical to support its deployment to a production system. A key AI enabler is ontology-guided search using domain-sp...

Algorithmic analysis of models is quite common in general, but is rarely attempted in the context of agent-based social simulation. We explore the algorithmic analysis of simulation models that take the form of production systems as these are defined in computer science. Several implemented analysis algorithms for a particular type of production system are discussed, including algorithms for ag...

This paper discusses a developmental paradox, namely that children’s performance in language production sometimes exceeds their performance in language comprehension. This yields a puzzle for most theories of language acquisition. If a child produces a linguistic form correctly, this is considered to be evidence that the child possesses the relevant grammatical knowledge. However, if the child ...

Eye-movement patterns during reading are consistent with proposition-byproposition models of speech comprehension. (1) Fixation times ore least offected by word length ot ends of clauses: this confirms the theory based on the study of speech comprehension that, at such points, attention is directed inward to text integration. (2) Fixotion time for words ot the end of clauses is longer for canon...

Abstract Genre-based approach has been the focus of interest in the teaching of language since the mid1980s. Genre is defined in terms of the use of language in conventionalized communicative settings. The present study made an attempt to scrutinize the effects of genre-based pedagogy on Iranian Pre-intermediate EFL leaners' reading comprehension as well as the interaction between their reading...

Stories are used extensively for human communication; both the comprehension and production of oral and written narratives constitute a fundamental part of our experience. While study of this topic has largely been the domain of cognitive psychology, neuroscience has also made progress in uncovering the processes underlying these abilities. In an attempt to synthesize work from both literatures...
