OBJECTIVE To explore different user-interface designs for structured progress note entry, with a long-term goal of developing design guidelines for user interfaces where users select items from large medical vocabularies. DESIGN The authors created eight different prototypes of a pen-based progress-note-writing system called PEN-Ivory. Each prototype allows physicians to write patient progres...

Because of the benefits of standardization in healthcare data for research, decision support, and quality assessment, much research effort focuses on collection of structured patient data. Many strategies to obtain such data are based on controlled vocabularies to guide data entry in a far more flexible way than a fixed-form approach. Medical controlled vocabularies evolve, but change is diffic...

Controlled and uncontrolled indexing terminology and metadata may be converted from one to another. Decision criteria are developed that can be used to determine which terms should be assigned when converting vocabularies. Methods are developed for computing the parameters of these systems, as well as means for estimating the parameters when given limited information. These conversion technique...

With the standardization of SKOS 1 (Simple Knowledge Organization System) in August 2009 a data model has been offered to publish controlled vocabularies and taxonomies on the web in a technical and semantically interoperable way. The heterogeneous environment of various vocabularies worldwide can be technically harmonized prospectively and especially the content of traditional databases can be...

We consider how the construction of multi-structured documents implies the definition of structuration vocabularies. In a multiusers context, the growth of these vocabularies has to be controlled. Therefore, we propose using the trace of users activity to limit this growth and document the vocabularies. A user will, for example, be able to follow and annotate the track of a vocabulary concept: ...

The high heterogeneity of biomedical vocabulary is a major obstacle for information retrieval in large biomedical collections. Therefore, using biomedical controlled vocabularies is crucial for managing these contents. We investigate the impact of query expansion based on controlled vocabularies to improve the effectiveness of two search engines. Our strategy relies on the enrichment of users' ...

Controlled vocabularies are common within bioinformatics resources. They can be used to give a summary of the knowledge held about a particular entity. They are also used to constrain values given for particular attributes of an entity. This helps create a shared understanding of a domain and aids increased precision and recall during querying of resources. Ontologies can also provide such faci...

Controlled vocabularies provide a roadmap through complex biological data. Proteomic data is increasing in volume and is currently poorly served by public repositories due to the large number of different formats in which the data is generated and stored. The Human Proteome Organization Proteome Standards Initiative is establishing standards for data transfer and deposition. These standards uti...
