This document discusses using ontologies to semantically normalize immunological data from the Human Immune Profiling Consortium (HIPC). 57 ontologies covering domains like anatomy, disease, pathways were evaluated. Text from HIPC datasets and protocols was annotated using these ontologies, with the NCI Thesaurus, Medical Subject Headings, and Gene Ontology mapping to the most terms. Many failures were due to missing commercial reagent terms. The conclusions are that ImmPort, the HIPC data repository, could adopt ontology-based encoding with additions to ontologies and text pre-processing.
