The Pursuit of Word Meanings.
We evaluate here the performance of four models of cross-situational word learning: two global models, which extract and retain multiple referential alternatives from each word occurrence; and two local models, which extract just a single referent from each occurrence. One of these local models, dubbed Pursuit, uses an associative learning mechanism to estimate word-referent probability but pur...
متن کاملDo Word Meanings Exist?
My contribution to this discussion is to attempt to spread a little radical doubt. Since I have spent over 30 years of my life writing and editing monolingual dictionary definitions, it may seem rather odd that I should be asking, do word meanings exist?

Being able to find out what people feel about a specific topic, be it a marketed product, a public person or a political issue, represents a very interesting application for a large class of actors, from the everyday product and se...
متن کاملThe Learning of Subordinate Word Meanings
In three experiments, adults attempted to learn words with subordinate-level meanings (dalmatian) by sampling the referent world cross-situationally. Xu & Tenenbaum, 2007 predicted that encountering three uses of a word, each referring to a dalmatian would evoke “suspicious coincidence” inferencing, leading to the subordinate meaning (dalmatian). Exp. 1 found little evidence for this; cross-sit...
متن کاملLearning Word Meanings From Examples
This paper describes work in progress on a computer program that uses syntactic constraints to derive the meanings of verbs from an analysis of simple English example stories. The central idea is an extension of Winston's (Winston 1975) program that learned the structural descriptions of blocks world scenes. In the new research, English verbs take the place of blocks world objects like ARCH and...
