This is the final update for the SemMedDB Database.
We have deleted all previous versions of the SemMedDB database (versions 31, 40, 41, and 42).
The databases downloadable here (from version 3.0 on) have been created using the new database schema (The schema and database information is available here).
The file names consist of five parts:
The letter R represents that the database was generated with standard SemRep options.
The new database schema differs from the previous one (versions 2X) in the following ways:
We no longer produce an annual release of the database of predications generated by SemRep using the sortal anaphora resolution. For sortal anaphora resolution in SemRep, see our BMC Bioinformatics paper.
The GENERIC_CONCEPT table has been updated in the June 30 2018 and all subsequent releases. Consequently, the SUBJECT_NOVELTY and OBJECT_NOVELTY columns of the PREDICATION table have been updated as follows: If the concept is not in the GENERIC_CONCEPT table, the value is set to 1; otherwise, it is set to 0.
Starting with version VER40, the PMID column in SENTENCE is dependent on the PMID in the CITATION table with a foreign key constraint. Therefore, all the PMIDs in the SENTENCE table have corresponding rows in the CITATION table, which has metadata PMID information.
