  1. STUDY DESIGN: Repeated measures design. OBJECTIVE: To describe male spine movement and posture characteristics during coitus and compare these characteristics across 5 common coital positions. SUMMARY OF BACKGROUND DATA: Exacerbation of pain…
  2. Ontologies have become core components of many large applications yet the training material has not kept pace with the growing interest. This paper addresses the issues of why one would build an ontology and presents a methodology for creating…
  3. Ontologies, as sets of concepts and their interrelations in a specific domain, have proven to be a useful tool in the areas of digital libraries, the semantic web, and personalized information management. As a result, there is a growing need for…
  4. The widespread use of paper or document-based forms for capturing patient information in various clinical settings, for example in epilepsy centers, is a critical barrier for large-scale, multi-center research studies that require interoperable,…
  5. This paper gives an overview of current trends in manual indexing on the Web. Along with a general rise of user generated content there are more and more tag- ging systems that allow users to annotate digital resources with tags (keywords) and share…
  6. A major use of medical ontologies is to support coding systems for use in electronic healthcare records and messages. A key task is to define which codes are to be used where – to bind the terminology to the model of the medical record or message.…
  7. MetaMap is a widely available program providing access to the concepts in the unified medical language system (UMLS) Metathesaurus from biomedical text. This study reports on MetaMap's evolution over more than a decade, concentrating on those…
  8. Semantic interoperability is essential to facilitate the computerized support for alerts, workflow management and evidence-based healthcare across heterogeneous electronic health record (EHR) systems. Clinical archetypes, which are formal…
  9. Research on ontologies is becoming widespread in the biomedical informatics community. At the same time, it has become apparent that the challenges of properly constructing and maintaining ontologies have proven more difficult than many workers in…
  10. Some modern Electronic Healthcare Record (EHR) architectures and standards are based on the dual model-based architecture, which defines two conceptual levels: reference model and archetype model. Such architectures represent EHR domain knowledge by…
  11. In designing Jabberwocky—a speech-based interface to Microsoft PowerPoint—we have tried to go beyond simple commands like “Next slide, please” and make a tool that aids speakers as they present and even learns as they rehearse their presentations.…
  12. We demonstrate by means of simple, noninvasive methods (analysis of satellite images, field observations, and measuring "deer beds" in snow) that domestic cattle (n = 8,510 in 308 pastures) across the globe, and grazing and resting red and roe deer…
  13. We examine certain features of popular myths regarding ghosts, vampires and zombies as they appear in film and folklore. We use physics to illuminate inconsistencies associated with these myths and to give practical explanation to certain aspects.
