This study of second- and third-grade students in the Netherlands tests the hypothesis that simplification of the semantic structure will facilitate semantic understanding and acquisition of syntax knowledge within the LOGO Turtle World. Two microworlds were designed applying the theory of automata and abstract languages. (Author/LRW)

Introduces the Knowledge Digraph Contribution (KDC) data-analysis methodology for quantitatively measuring the degree to which a given knowledge digraph can account for the occurrence of specific sequences of propositions in recall, summarization, talk-aloud and question-answering protocol data. Notes the applicability of this approach to the…

Illustrates use of Latent Semantic Analysis (LSA) for predicting coherence through reanalyzing two studies that manipulated coherence of texts and assessed readers' comprehension. Finds that LSA predicts effects of text coherence on comprehension. Notes that LSA can be applied as an automated method that produces coherence predictions similar to…

Argues that researchers in the area of discourse comprehension and mental representation of discourse will likely feel motivated to adopt highly quantitative research techniques described in the articles in this special issue. Notes that ability to do so will be enhanced by availability of well-documented, easy-to-use computer software, or…

This study analyzed the spontaneous speech of eight Israeli children (ages 3-6) with congenital neurological syndromes (NS) and cognitive impairments. Comparison with language-matched controls found no differences on 10 grammatical variables and slight differences on 3 semantic-pragmatic variables. Findings suggest a mechanism functionally akin to…

Investigated the influence of morphologically complex and simple words on the production of morphologically complex and simple picture names in five picture-word interference studies. Two variants of picture-word interference were employed to separate morphological from semantic and phonological effects. (Author/VWL)

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.

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)
