Synonyms
COVID-19 related terms/concepts are available here.
A great addition to EMERSE is our large collection of manually curated terms and phrases that we call Synonyms. This dataset was created for term expansion, to help users find related concepts that they might otherwise miss. The Synonyms collection is a work in progress — new terms are added all the time. It currently contains over 1.2 million unique entries. The synonyms collection contains a wide variety of terms related to diseases, medications (prescription, over-the-counter, herbal, etc), symptoms, infectious agents, test names, anatomical names, misspellings (120,000 of them), and other variants. A subset of the types of categories, with examples, are shown below.

* Note that the dataset does not formally label each element with the categories listed above. Rather, the terms are simply connected due to whatever relevant relationship they have with one another.
Figure. Example of Synonyms displayed for an EMERSE user who was initially searching for the phrase "back pain"
Some terms are included that clinicians may not even consider to be real terms. For example, menorrhagia is considered a synonym of hypermenorrhea. These two terms are are also grouped with hypermenorrhagia, the latter of which is not a true medical term but nevertheless appears in the clinical notes of more than 500 of our patients.
Within EMERSE, Synonyms are used as system-provided suggestions, but users can always include their own terms in their searches. Additionally, it is possible for EMERSE system administrators to include additional terms that would then be available to all users of the system, perhaps needed for unique local terminologies.
The Synonyms were created specifically to help with string matching in EMERSE, but the dataset clearly has utility for other tasks including text mining, information retrieval (IR), natural language processing (NLP), machine learning (ML), and artificial intelligence (AI). The Synonyms collection can be licensed from the University of Michigan Office of Technology Transfer. Both Academic and Commercial Licenses are available. For more about the Synonyms, or to see a sample dataset, please Contact the EMERSE team. For details about licensing opportunities, please Contact the Office of Technology Transfer.
