Although the goal of achieving semantic interoperability of electronic health
records (EHRs) is pursued by many researchers, it has not been accomplished
yet. In this paper, we present a proposal that smoothes out the way toward the
achievement of that goal. In particular, our study focuses on medical diagnoses
statements. In summary, the main contributions of our ontology-based proposal
are the following: first, it includes a canonical ontology whose EHR-related
terms focus on semantic aspects. As a result, their descriptions are
independent of languages and technology aspects used in different organizations
to represent EHRs. Moreover, those terms are related to their corresponding
codes in well-known medical terminologies. Second, it deals with modules that
allow obtaining rich ontological representations of EHR information managed by
proprietary models of health information systems. The features of one specific
module are shown as reference. Third, it considers the necessary mapping axioms
between ontological terms enhanced with so-called path mappings. This feature
smoothes out structural differences between heterogeneous EHR representations,
allowing proper alignment of information.

通过提出基于本体论的建议，该研究聚焦于医疗诊断陈述，解决电子健康记录的语义互操作性问题，包括使用具有语义方面的 EHR 相关术语的标准本体论和路径映射来解决异构系统之间的结构差异问题。
