Discussion of methodologies for the semantic integration of databases focuses on formalizing the notion of schema equivalence and the schema integration process. Topics include common data model; the Entity-Relationship (ER)model; transformation of ER models; transformational, mapping, and behavioral schema equivalence; and knowledge-based…

Discussion of data repositories available in global information systems focuses on facilitating access by providing semantic views. Highlights include the mapping relation; syntax and semantics of the mapping; query formulation and processing; terminological systems for semantic views; and relational algebraic expressions. (LRW)

Three primed naming experiments were conducted to investigate development of sublexical processing in reading Chinese. Target characters were either homophonic to or semantically related to phonetic radicals embedded in irregular complex characters, but not to the complex characters themselves. (Author/VWL)

Three experimental techniques that can be used to investigate the gradient of discrete nature of intonational differences, the semantic task, the imitation task, and the pitch range task are discussed and evaluated. It is pointed out that categorical perception is a sufficient but not a necessary, property of phonological discreteness. (Author/VWL)

Eight commentaries are provided on an article examining the means by which bilinguals control their two language systems. (Author/VWL)

Replies to commentaries written by eight peers in response to an article the author wrote on the means by which bilinguals control their two language systems and in which he proposed an inhibitory control model that embodies the principle that there are multiple levels of control. (Author/VWL)

Presents the semantic information theory, formulated by the philosopher Fred Dretske, as a contribution to the discussion of metatheories and their practical implications in library and information science. Highlights include mathematical communication theory; digitization, perception, cognition, and concept formation; information and knowledge;…

Presents exploratory research evaluating a conceptual structure for the description of visual content of images. The structure classifies visual attributes into a "Pyramid" containing four syntactic levels and six semantic levels. Experiments performed suggest the Pyramid is conceptually robust and can be used to: organize visual content…

Patient WBN has a lexical-semantic deficit resulting in impaired performance on language comprehension tasks that require access to verb meanings in both single-word and sentence contexts. However, WBN shows no such comprehension impairment with respect to lexical syntax. Specifically, he performs without error on comprehension tasks that rely on…

The present case continues the series of anomia treatment studies with contextual priming (CP), being the second in-depth treatment study conducted for an individual suffering from semantically based anomia. Our aim was to acquire further evidence of the facilitation and interference effects of the CP treatment on semantic anomia. Based on the…

Four experiments examined whether studying a single Deese/Roediger-McDermott (DRM) list produces semantic priming for nonstudied critical items (CIs) and semantic + repetition priming for studied associates. After 30 s of mental arithmetic that followed the study of a DRM list, priming was assessed in a lexical decision task when the nonwords were…

The present study investigated the abilities of left-hemisphere-damaged (LHD) non-fluent aphasic, right-hemisphere-damaged (RHD), and normal control individuals to access, in sentential biasing contexts, the multiple meanings of three types of ambiguous words, namely homonyms (e.g., ''punch''), metonymies (e.g., ''rabbit''), and metaphors (e.g.,…

Although children take over a year to learn the meanings of the first three number words, they eventually master the logic of counting and the meanings of all the words in their count list. Here, we ask whether children's knowledge applies to number words beyond those they have mastered: Does a child who can only count to 20 infer that number…

nstraints, phonotactic probabilityThe effects of phonotactic constraints (i.e., the status of a sound as correctly or incorrectly articulated) and phonotactic probability (i.e., the likelihood of a sound sequence) on lexical acquisition have been investigated independently. This study investigated the interactive influence of phonotactic…

Most, if not all, of the studies of subtypes of children with language impairments have been conducted with English-speaking children. The possibility and validity of identified subtypes for non-English clinical populations are, as yet, unknown. This study was designed to provide cross-linguistic evidence of language subtypes. A broad battery of…
