This paper describes adaptations of unsupervised word sense discrimination techniques to the problem of name discrimination. These methods cluster the contexts containing an ambiguous name, such that each cluster refers to a unique underlying person or place. We also present new techniques to assign meaningful labels to the discovered clusters.

The purpose of this study was to investigate the visual discrimination abilities of regular class children with varying levels of word recognition skill and of special class children. Word recognition and intelligence scores were obtained on 90 primary-aged children in regular classes and on seven children in a special class. The subjects were required to match twelve standard graphemes with an...

Consistent with long-standing findings from behavioral studies, neuroimaging investigations have identified a region of the inferior temporal cortex that, in adults, shows greater face selectivity in the right than left hemisphere and, conversely, a region that shows greater word selectivity in the left than right hemisphere. What has not been determined is how this pattern of mature hemispheri...

Formality is an important dimension of language style. Texts of different genres tend to have different degrees of formality. F-score (formality-score) is a most popular measure for formality to differ genres. It uses a method of combining proportions of words of different types, with nouns, adjectives, articles and prepositions as positive elements, and adverbs, verbs and interjections as nega...

This paper addresses the questions of whether lexical information influences phoneme discrimination in children with cochlear implants (CI) and whether this influence is similar to what occurs in normal-hearing (NH) children. Previous research with CI children evidenced poor accuracy in phonemic perception, which might have an incidence on the use of lexical information in phoneme discriminatio...

Sense induction seeks to automatically identify word senses of polysemous words encountered in a corpus. Unsupervised word sense induction can be viewed as a clustering problem. In this paper, we used the Hierarchical Clustering Algorithm as the classifier for word sense induction. Experiments show the system can achieve 72% F-score about train-corpus and 65% F-score about test-corpus.

OBJECTIVES To date, limited and inconsistent evidence exists regarding racial discrimination and risk of cardiovascular disease (CVD). METHODS Cross-sectional observational study of 1005 US-born non-Hispanic black (n = 504) and white (n = 501) participants age 35-64 randomly selected from community health centers in Boston, MA (2008-2010; 82.4% response rate), using 3 racial discrimination me...

MOTIVATION In molecular biology, molecular events describe observable alterations of biomolecules, such as binding of proteins or RNA production. These events might be responsible for drug reactions or development of certain diseases. As such, biomedical event extraction, the process of automatically detecting description of molecular interactions in research articles, attracted substantial res...

The word-frequency effect (WFE) in recognition memory refers to the finding that more rare words are better recognized than more common words. We demonstrate that a familiarity-discrimination model operating on data from a semantic word-association space yields a robust WFE in data on both hit rates and false-alarm rates. Our modeling results suggest that word frequency is encoded in the semant...
