Explains how a competition-based connectionist model for diagnostic problem-solving is adapted to information retrieval. Topics include probabilistic causal networks; Bayesian networks; the neural network model; empirical studies of test collections that evaluated retrieval performance; precision results; and the use of a thesaurus to provide…

Describes the erroneous use of the term "dissolve" in chemistry textbooks to refer to what is, more properly speaking, a chemical reaction. (WRM)

Examines mealtimes of preschoolers' families to determine whether rare words are used in informative ways so that a child could learn their meanings. Each use was coded for whether it was informative or uninformative; each informative exchange was coded for type of strategy used to provide support. Frequency of use was positively correlated with…

Investigated the hierarchical organization of the semantic system in preschoolers with and without word-finding deficits. Children named a series of objects at multiple levels of the noun hierarchy in response to contrast questions. Children with word-finding deficits had similar abilities to the other children but did not have enough stored…

Synthesizes work on research concerned with the influence of a second language on speaker's first language competence in late bilingualism. Research in the areas of phonology, morphosyntax, lexis, semantics, pragmatics, rhetoric, and conceptual representations suggests that borrowing, convergence, shift, restructuring, and loss result from the…

Analyzed the argument linking of the commercial transaction frame in English, Russian, and Japanese. The commercial transaction frame is semantically complex, because there are two transfers in opposite directions (money goes from buyer to seller and goods from seller to buyer). English and Russian construe the commercial frame in essentially the…

Investigated the interface of form and function in the acquisition of negation in Cantonese-speaking children. Data--from the Hong Kong Cantonese Child Language Corpus--were longitudinal spontaneous samples of eight children aged 1.5 to 3.8 years. Main issues in the study were the sequence of emergence of negative markers and the acquisition of 11…

This article reviews the cultural and linguistic background of Asian Indians in the United States. It highlights some of the phonological, grammatical, semantic, and vocabulary usage peculiarities of the variety of English called Indian English spoken by immigrants from the Indian subcontinent. (Author/DB)

Describes EquiX, a search language for XML that combines querying with searching to query the data and the meta-data content of Web pages. Topics include search engines; a data model for XML documents; search query syntax; search query semantics; an algorithm for evaluating a query on a document; and indexing EquiX queries. (LRW)

Investigated whether: (1) the role of phonological and orthographic activation differs during semantic processing of Korean Hangul and Hanja and (2) proficiency in Korean Hanja would affect the way phonology is used in comprehension of Hanja characters. Overall, results indicate both language proficiency and script difference can affect the…

Responds to an article that argues that in the study of bilingualism, conceptual representations should be treated as related but not equivalent to word meanings, as knowledge-based, dynamic and language- and culture-specific. (Author/VWL)

We assessed the impact of visual similarity on written word identification by having participants learn new words (e.g. BANARA) that were neighbours of familiar words that previously had no neighbours (e.g. BANANA). Repeated exposure to these new words made it more difficult to semantically categorize the familiar words. There was some evidence of…

This study uses the morphological family size effect as a tool for exploring the degree of isomorphism in the networks of morphologically related words in the Hebrew and Dutch mental lexicon. Hebrew and Dutch are genetically unrelated, and they structure their morphologically complex words in very different ways. Two visual lexical decision…

Spaced retrieval (SR) has recently been modified to target anomia in persons with aphasia (PWA). It relies on a strict management of the inter-stimulus interval (ISI) where the time between stimulus presentations is doubled or halved based on response accuracy. Although SR is successful in treating anomia, it remains to be studied whether the…

The lexical-semantic and syntactic abilities of a group of individuals with chronic nonthalamic subcortical (NS) lesions following stroke (n=6) were investigated using the Western Aphasia Battery (WAB) picture description task [Kertesz, A. (1982). "The Western aphasia battery." New York: Grune and Stratton] and compared with those of a…
