An ontology-driven tool for structured data acquisition using Web forms

Structured data acquisition is a common task that is widely performed in biomedicine. However, current solutions for this task are far from providing a means to structure data in such a way that it can be automatically employed in decision making (e.g., in our example application domain of clinical functional assessment, for determining eligibility for disability benefits) based on conclusions derived from acquired data (e.g., assessment of impaired motor function). To use data in these settings, we need it structured in a way that can be exploited by automated reasoning systems, for instance, in the Web Ontology Language (OWL); the de facto ontology language for the Web.We tackle the problem of generating Web-based assessment forms from OWL ontologies, and aggregating input gathered through these forms as an ontology of "semantically-enriched" form data that can be queried using an RDF query language, such as SPARQL. We developed an ontology-based structured data acquisition system, which we present through its specific application to the clinical functional assessment domain. We found that data gathered through our system is highly amenable to automatic analysis using queries.We demonstrated how ontologies can be used to help structuring Web-based forms and to semantically enrich the data elements of the acquired structured data. The ontologies associated with the enriched data elements enable automated inferences and provide a rich vocabulary for performing queries.

Medical Education in the Electronic Medical Record (EMR) Era: Benefits, Challenges, and Future Directions
2013; 88 (6): 753-757
In the last decade, electronic medical record (EMR) use in academic medical centers has increased. Although many have lauded the clinical and operational benefits of EMRs, few have considered the effect these systems have on medical education. The authors review what has been documented about the effect of EMR use on medical learners through the lens of the Accreditation Council for Graduate Medical Education's six core competencies for medical education. They examine acknowledged benefits and educational risks to use of EMRs, consider factors that promote their successful use when implemented in academic environments, and identify areas of future research and optimization of EMRs' role in medical education.
