IEDB PubMed abstract triaging process. Abstracts of references retrieved from the PubMed queries that have not been introduced to the IEDB's database and curation pipeline proceed to at least one of four hierarchical levels of classification. At Level 0, an abstract is evaluated for epitope-specific content. Abstracts which contain epitope-specific data are assigned to one of the seven Level 1 categories. References receive increasingly specific category assignments at Levels 2 and 3. High IEDB priority categories are Allergy, Autoimmunity, Infectious Disease, and Transplantation. Low IEDB priority categories are Cancer, HIV, and Other. Transplant and Cancer references are not assigned Level 2 categories. HIV references do not receive Level 2 or 3 category assignments.
