Semantic MEDLINE Database

The Semantic MEDLINE Database (SemMedDB) [1] is a repository of semantic predications (subject-predicate-object triples) extracted by SemRep, a semantic interpreter of biomedical text [2]. SemMedDB currently contains information about approximately 91.6 million predications from all of PubMed citations (about 27.2 million citations, as of June 30 2017) and forms the backbone of the Semantic MEDLINE application [3, 4].

To download the SemMedDB, a UTS account is required. Users that already have one need to click here and provide their UTS account information. To get a UTS account, click here.
