Meaning Acquisition from Interaction Data with Fisher's Exact Test

Functional Neuroanatomy of Meaning Acquisition from Context

An important issue in language learning is how new words are integrated in the brain representations that sustain language processing. To identify the brain regions involved in meaning acquisition and word learning, we conducted a functional magnetic resonance imaging study. Young participants were required to deduce the meaning of a novel word presented within increasingly constrained sentence...

Automatic Acquisition of Word Meaning from Context

AUTOMATIC ACQUISITION OF WORD MEANING FROM CONTEXT by Peter Mark Hastings Chair: Assistant Professor Steven Lytinen This thesis presents an automatic, incremental lexical acquisition mechanism that uses the context of example sentences to guide inference of the meanings of unknown words. The goal of this line of research is to allow a Natural Language Processing (NLP) system to cope with words ...

Linguistic Meaning from the Language Acquisition Perspective

From a plausible cognitive hypothesis explaining how little children develop complex meaning structures, we come to the conclusion that linguistic meanings are planned. The plans, we call them discourse plans, are tree-like structures composed of primitive situations and establishing referential links between the situations and the context. Linguistic meanings are second order Lambda-terms deri...

Fisher’s Exact Test for Misclassified Data

Extracting meaning from microarray data.

Gene expression is complex: many mRNAs change in abundance in response to a new condition. But while some of these expression changes may be direct, many may be downstream, indirect effects. One of the major problems of microarray data analysis is distinguishing between these changes. Some of the most common methods of analysis are discussed, in the context of their ability to distinguish betwe...
