Mapping medical concepts from a terminology system to the concepts in the narrative text of a medical document is necessary to provide semantically accurate information for further processing steps. The MetaMap Transfer (MMTx) program is a semantic annotation system that generates a rough mapping of concepts from the Unified Medical Language System (UMLS) Metathesaurus to free medical text, but this mapping still contains erroneous and ambiguous bits of information. Since manually correcting the mapping is an extremely cumbersome and time-consuming task, we have developed the MapFace editor.

The editor provides a convenient way of navigating the annotated information gained from the MMTx output, and enables users to correct this information on both a conceptual and a syntactical level, and thus it greatly facilitates the handling of the MMTx program. Additionally, the editor provides enhanced visualization features to support the correct interpretation of medical concepts within the text. We paid special attention to ensure that the MapFace editor is an intuitive and convenient tool to work with. Therefore, we recently conducted a usability study in order to create a well founded background serving as a starting point for further improvement of the editor's usability.

将医学概念从术语系统映射到医学文档的叙述文本中的概念对于为进一步处理步骤提供语义上准确的信息是必要的。MetaMap Transfer (MMTx) 程序是一种语义注释系统，可生成从统一医学语言系统 (UMLS) 元叙词到自由医学文本的概念的粗略映射，但该映射仍包含错误和模糊的信息位。由于手动校正映射是一项极其繁琐且耗时的任务，因此我们开发了 MapFace 编辑器。

编辑器提供了一种方便的方式来导航从 MMTx 输出中获得的注释信息，并使用户能够在概念和语法级别上更正这些信息，从而极大地方便了 M​​MTx 程序的处理。此外，编辑器提供了增强的可视化功能，以支持对文本中医学概念的正确解释。我们特别注意确保 MapFace 编辑器是一个直观且方便的工具。因此，我们最近进行了可用性研究，以创建一个良好的背景，作为进一步提高编辑器可用性的起点。
