Search technologies are critical to enable clinical staff to rapidly and effectively access patient information contained in free-text medical records. Medical search is challenging as it suffers from the semantic gap problem: the mismatch between the raw data and the way a human being interprets it. Valuable domain knowledge explicitly represented in structured knowledge resources such as ontologies (e.g. SNOMED CT) can potentially be leveraged to support such semantic inferences.
The focus of our research is on medical record searching and analytics using text , concepts , annotations , and SNOMED CT subsumption and relation querying [4-6].
