solving power flow problems with a matlab implementation of the power system applications Data Dictionary
Decision Support Systems, 2001Co-Authors: F.l. AlvaradoAbstract:Abstract This paper implements a power flow application and variations using the IEEE Power System Application Data Dictionary (PSADD) within a Matlab environment. It describes a number of useful Data and implementation techniques for a variety of applications. The techniques include the use of very compact and efficient code for the computation of Power Transfer Distribution Factors (PTDF). PTDF are an important element of present and proposed congestion management strategies for power systems, particularly when these systems must operate in a deregulated environment.

evaluation of the expressiveness of an icnp based nursing Data Dictionary in a computerized nursing record system
Journal of the American Medical Informatics Association, 2006Co-Authors: Hyeounae ParkAbstract:This study evaluated the domain completeness and expressiveness issues of the International Classification for Nursing Practice-based (ICNP) nursing Data Dictionary (NDD) through its application in an enterprise electronic medical record (EMR) system as a standard vocabulary at a single tertiary hospital in Korea. Data from 2,262 inpatients obtained over a period of 9 weeks (May to July 2003) were extracted from the EMR system for analysis. Among the 530,218 Data-input events, 401,190 (75.7%) were entered from the NDD, 20,550 (3.9%) used only free text, and 108,478 (20.4%) used a combination of coded Data and free text. A content analysis of the free-text events showed that 80.3% of the expressions could be found in the NDD, whereas 10.9% were context-specific expressions such as direct quotations of patient complaints and responses, and references to the care plan or orders of physicians. A total of 7.8% of the expressions was used for a supplementary purpose such as adding a conjunction or end verb to make an expression appear as natural language. Only 1.0% of the expressions were identified as not being covered by the NDD. This evaluation study demonstrates that the ICNP-based NDD has sufficient power to cover most of the expressions used in a clinical nursing setting.

The MPEG-21 rights expression language and rights Data Dictionary
IEEE Transactions on Multimedia, 2005Co-Authors: Xin Wang, T. Demartini, B. Wragg, M. Paramasivam, C. BarlasAbstract:The MPEG-21 Rights Expression Language (REL) is an XML-based language for digital rights management (DRM), providing a universal method for specifying rights and conditions associated with the distribution and use of assets like content, resources and services. Evolved from the eXtensible rights Markup language (XrML), the REL facilitates the creation of an open DRM architecture for managing and protecting these assets. As a general-purpose rights expression language, the REL is agnostic to types of assets, platforms and media, and expressive enough to support applications that can be even beyond DRM, including protecting privacy. It also contains additional capabilities in the areas of extensibility, security, trust management, and life cycle management of rights. This article provides an overview of the REL in terms of its Data model, expressiveness, authorization model, structure for extensibility and profiling, and usages in digital media, trust management, and web services. To support the REL and provide extensive semantics for the management of rights, MPEG-21 also defined a Rights Data Dictionary (RDD). Based on original work conducted by , the MPEG-21 RDD specifies a methodology and structure for the RDD Dictionary. The specification defines a core set of terms and provides a mechanism for the introduction of further terms through a registration authority. The RDD also supports the mapping of terms from different namespaces.

development of a Data Dictionary for the strategies for post arrest resuscitation care sparc network for post cardiac arrest research
Resuscitation, 2011Co-Authors: Laurie J Morrison, Steven C BrooksAbstract:Abstract Background The widely accepted Utstein style has standardized Data collection and analysis in resuscitation and post resuscitation research. However, collection of many of these variables poses significant practical challenges. In addition, several important variables in post resuscitation research are missing. Objective Our aim was to develop a comprehensive Data Dictionary and web-based Data collection tool as part of the Strategies for Post Arrest Resuscitation Care (SPARC) Network project, which implemented a knowledge translation program for post cardiac arrest therapeutic hypothermia in 37 Ontario hospitals. Methods A list of Data variables was generated based on the current Utstein style, previous studies and expert opinion within our group of investigators. We developed a Data Dictionary by creating clear definitions and establishing abstraction instructions for each variable. The Data Dictionary was integrated into a web-based collection form allowing for interactive Data entry. Two blinded investigators piloted the Data collection tool, by performing a retrospective chart review. Results A total of 454 variables were included of which 400 were Utstein, 2 were adapted from existing studies and 52 were added to address missing elements. Kappa statistics for two outcome variables, survival to discharge and induction of therapeutic hypothermia were 0.86 and 0.64, respectively. Conclusion This is the first attempt in the literature to develop a Data Dictionary as part of a standardized, pragmatic Data collection tool for post cardiac arrest research patients. In addition, our Dataset defined important variables that were previously missing. This Data collection tool can serve as a reference for future trials in post cardiac arrest care.

ISMIR - Data Dictionary: MetaData for Phonograph Records.
2020Co-Authors: Ichiro FujinagaAbstract:The creation and maintenance of a metaData Data Dictionary is essential to large-scale digital repositories. It assists the process of Data entry, ensures consistency of records, facilitates semantic compatibility and interoperability between systems, and, most importantly, forms the foundation for efficient and effective information retrieval infrastructure. In this paper we explain in detail the necessity of metaData Data dictionaries to digitization projects and digital library retrieval services. We also describe the development process of our Data Dictionary for phonograph records. We then present the underlying Data model of our Data Dictionary and provide information about the meaning and use of semantic units defined in the Data Dictionary. We stress the usefulness of the generation and maintenance of our Data Dictionary for MIR as it provides a means to ensure accurate, consistent, and comprehensive metaData annotation. For maximum interoperability between systems, digital repositories not only need to agree on the same metaData fields, but also the meanings of the fields. To this end, we believe our Data Dictionary is the cornerstone of optimal retrieval of music information about phonograph records.
