Adaptive hypermedia systems may support adaptive presentation and/or adaptive navigation. A general architecture for a hypermedia system supporting adaptive nodes is presented here. User experiments with a prototype implementation are described. The general problem of evaluation and planned future work is then addressed.

Existing ontology-related formalisms focus on either datatypes (such as the OWL datatype formalism) or datatype predicates (such as the concrete domain approach). Furthermore, they don’t provide a general framework for representing customised datatypes and predicates, which is identified as a key requirement of ontology languages. In this paper we shall propose a scheme for integrating concept ...

To the Editor: The corneal deposits seen in heterozygote granular corneal dystrophy type 2 (GCD2) can be observed in individuals with variable appearances.1 When the deposits are small and at times undetectable, only genetic analysis is effective for the confirmative diagnosis. Many refractive surgeons have adopted genetic testing prior to refractive surgery to verify that their patients are fr...

Contributions of different experts to innovation projects improve enterprise value, captured in documents. A subset of them is the centre of expert constraint convergence. Their production needs to be tailored case by case. Documents are very often considered as knowledge transcription. As the base of a structured knowledge-based information environment, this paper presents a global approach th...

BACKGROUND Large-for-gestational-age (LGA) or macrosomic infants are associated with adverse maternal and neonatal outcomes. It is unclear if these associations are stronger using customised birthweight centiles. We compared outcomes between term infants defined macrosomic by birthweight >4000 g (Macro(4000) ) or LGA by population centiles (LGA(pop) ) with those defined LGA by customised centil...

OBJECTIVE We wanted to compare customised and population standards for defining smallness for gestational age (SGA) in the assessment of perinatal mortality risk associated with parity and maternal size. DESIGN Population-based cohort study. SETTING Sweden. POPULATION Swedish Birth Registry database 1992-1995 with 354 205 complete records. METHOD Coefficients were derived and applied to...

BACKGROUND There is limited evidence to support the use of customised centile charts to identify those at risk of stillbirth and infant death at term. We sought to determine birth weight thresholds at which mortality and morbidity increased and the predictive ability of noncustomised (accounting for gestational age and sex) and partially customised centiles (additionally accounting for maternal...
