Our objective was to enable an end-user to create complex queries to drug information sources through functional composition, by creating sequences of functions from application program interfaces (API) to drug terminologies. The development of a functional composition model seeks to link functions from two distinct APIs. An ontology was developed using Protégé to model the functions of the RxN...

Background: Clinical decision support systems and semantic mining require interoperable representations of pharmacologic classes across reference terminological systems. We explore two such systems: NDF-RT and

RxBatch 1 is a web interface for doing batch operations with the RxNorm and NDF-RT APIs. Notable features include: • Functional Composition. Instead of a single API function, a pipeline of functions to be executed in sequence can be specified. Any combination of interoperable functions from the RxNorm and NDF-RT APIs 2,3 is permitted. RxBatch automatically ensures the interoperability of functi...

Objectives: To demonstrate RxClass, a web interactive browser to explore the relationships between RxNorm drugs and drug classes from several sources including ATC, MeSH and NDF-RT. RxClass is publicly available at: http://mor.nlm.nih.gov/RxClass/ I. MOTIVATION Drug classes constitute important information about the drugs and are critical to important use cases, such as clinical decision suppor...

A dual-task paradigm was implemented using a repeated measures design to determine the time course of attention demands during performance of a soccer penalty kick. Experienced soccer players (N=15) were asked to perform a 12-yard soccer-style penalty kick. As part of the dual task paradigm, participants were instructed to respond to an audible cue that was administered during one of three prob...

Drug information sources use category labels to assist in navigating and organizing information. Some category labels describe drugs from multiple perspectives (e.g., both structure and function). The National Drug File - Reference Terminology (NDF RT) is a drug information source that augments a "legacy" categorization system with a formal reference model specifying Chemical Structure, Cellula...
