V-Model: A New Innovative Model to Chronologically Visualize Narrative Clinical Texts

摘要

Visualizing narrative medical events into a timeline can have positive effects on clinical environments. However, the characteristics of natural language and medical environments make this representation more difficult. This paper explains the obstacles and suggests a solution called the V-Model. The V-Model is a new innovative time model that was developed to represent chronological narrative events in a medical domain. Forty medical students participated in evaluating this model. The experimental results show the new model successfully solved the modeling requirements and had better usability compared to conventional timeline models. All the participants assessed the new timeline as very useful in effectively understanding a patient's history.
