13. On the design of ontology-driven workflow flexibilization mechanisms
Workflow management systems usually interpret a workflow definition rigidly. However, there are real life situations where users should be allowed to deviate from the prescribed static workflow definition for various reasons, including lack of information and unavailability of the required resources. To flexibilize workflow execution, this paper first propos

15. Attribute match discovery in information integration: exploiting multiple facets of metadata
Automating semantic matching of attributes for the purpose of information integration is challenging, and the dynamics of the Web further exacerbate this problem. Believing that many facets of metadata can contribute to a resolution, we present a framework for multifaceted exploitation of metadata in which we gather information about potential matches from v

16. Auditing the Unified Medical Language System with Semantic Methods
Abstract Objective: The National Library of Medicine's (NLM) Unified Medical Language System (UMLS) includes a Metathesaurus (Meta), which is a compilation of medical terms drawn from over 30 controlled vocabularies, and a Semantic Net, which contains the semantic types used to categorize Meta concepts and the semantic relations to connect them. Meta has

17. Different impairments of semantic cognition in semantic dementia and semantic aphasia: evidence from the non-verbal domain
Disorders of semantic cognition in different neuropsychological conditions result from diverse areas of brain damage and may have different underlying causes. This study used a comparative case-series design to examine the hypothesis that relatively circumscribed bilateral atrophy of the anterior temporal lobe in semantic dementia (SD) produces a gradual deg

18. Semantic memory and frontal executive function during transient global amnesia.
To assess semantic memory and frontal executive function, two patients underwent neuropsychological testing during transient global amnesia (TGA) and after an interval of 6-8 weeks. In spite of a profound deficit in anterograde verbal and non-verbal memory, semantic memory was normal, as judged by category fluency measures, picture naming, and picture-word a

19. Progressive language impairment without dementia: a case with isolated category specific semantic defect.
A patient is described with a 5 year progressive defect of naming and auditory verbal comprehension, the pathological nature of which was presumably degenerative. The auditory comprehension defect unevenly affected different semantic categories, and was particularly severe for the names of animals, fruits and vegetables. The patients showed loss of the verba

20. Neurology of anomia in the semantic variant of primary progressive aphasia
The semantic variant of primary progressive aphasia (PPA) is characterized by the combination of word comprehension deficits, fluent aphasia and a particularly severe anomia. In this study, two novel tasks were used to explore the factors contributing to the anomia. The single most common factor was a blurring of distinctions among members of a semantic cate

21. Lateralisation of cortical function during cognitive tasks: regional cerebral blood flow studies of normal individuals and patients with schizophrenia.
To assess cognitively-related regional asymmetries of brain function, regional cerebral blood flow (rCBF) was determined by the xenon inhalation method while normal subjects performed 10 different tasks and also while they were at rest. In addition to healthy subjects, patients with schizophrenia were also studied. A total of 447 rCBF studies were carried ou

22. Access to data: comparing AccessMed with Query by Review.
OBJECTIVE: To evaluate the performance of tools for authoring patient database queries. DESIGN: Query by Review, a tool that exploits the training that users have undergone to master a result review system, was compared with AccessMed, a vocabulary browser that supports lexical matching and the traversal of hierarchical and semantic links. Seven subjects (Me
