Outlines an approach to the automatic construction of a knowledge base resulting in a system that is able in each phase of its construction to acquire domain knowledge from all new information that it is building, particularly index terms. Topics covered include production rules, the use of semantic networks, and user interfaces. (32 references)…

A theory of deductive reasoning is presented for inferences that depend on multiply quantified premises. It is argued that reasoners construct mental models based on their knowledge of the meaning of the quantifiers. Three experiments, with 54 university students and adults, corroborated the theory. (SLD)

A discourse comprehension model is developed in which the initial processing is bottom-up. Word meanings are activated, propositions are formed, and inferences and elaborations are produced, regardless of the discourse context. A network of interrelated items is created which can be integrated into a coherent structure. (SLD)

Evaluates the effect of explicit instruction in second language reading comprehension strategies on intermediate-level French students' (N=53) reading comprehension and inferential ability, and seeks to determine what type of learners derive the greatest benefit from the instruction. The positive effect that reading strategy training has on…

Identifies some of the problems of attitude assessment in science education. Describes the development of the Attitude Toward the Subject Science Scale (ATSSS) and gives an overview of the Ajzen and Fishbein attitude theories. Provides five sample items. (YP)

Examines the limits of Julia Kristeva's approach to modernist language. The article argues that Kristeva draws on a structuralist model of language and the unconscious, utilizing a code and deviation framework, thereby restricting her ability to elucidate explicit effects of modernist dislocation of language. The article also probes the problems…

Contrary to the basic-level restraint hypothesis, which suggests that young children learn basic-level words more easily than specific-level words, these five studies show that although other constraints on word meaning may be in place, children are flexible in interpreting new words at different hierarchical levels. (MDM)

This study examined effects of familiarity with a speech target on coarticulation magnitude in 30 young children and 10 adults. Children exhibited a greater effect of a following vowel on the preceding fricative than did adults. Nonmeaningful production items exhibited greater effects of the vowel on the preceding fricative than did meaningful…

Experienced deaf-blind users (N=10) of sign language tested their ability to receive signed messages including isolated signs and sentences. A set of 122 isolated signs was received with an average accuracy of 87%. Signed sentence reception accuracy ranged from 60-85%, with errors accounted for primarily by deletions and phonological or…

Argues for a reconceptualization of second language learning in ways that account for the larger social and cultural forces that influence both the meanings residing in the linguistic resources used in face-to-face communication and the ability of individuals to use them. Also considers the sociohistorical significance of this perspective for…

This case study examined the vocabulary gains made by an adult learner of English as a Second Language as a result of performing four communication tasks. It found that explicit negotiation of word meaning appeared less deterministic of posttest improvements than use of words in the process of completing the task. (13 references) (MDM)

The growing secularization of Israeli lifestyle and the increasing influence of foreign languages as manifested in the local media have given rise to new forms of language secularization. This article discusses and provides examples of the secularization of Hebrew, which has split modern Hebrew into two varieties--religious and secularized. (13…

Unlike conventional information retrieval systems, natural language processing (NLP) systems translate queries automatically into the language of the system. This paper discusses the potential impact of NLP on both the indexing and retrieval of text and examines some current NLP projects and systems that have established knowledge bases in narrow…

After reviewing previous research on the acquisition of vocabulary through contextual clues, research carried out with 429 students in the upper grades of an Italian elementary school is discussed. (12 references) (CFM)

Word learning by young children is viewed as a problem deriving from the use of forms of discourse texts. Uses of causal and temporal terms in private speech by a child studied longitudinally from 1;9 to 3;0 are analyzed from this perspective. (Contains 38 references.) (JL)
