In MAA, a MeSH term and two tokens before and after the MeSH term are analyzed.
The "MeSH Term Active" retrieves assays in which only active compounds are annotated with the query MeSH term.
The "Complete MeSH Term" Entrez index retrieves compounds annotated with the MeSH term that exactly matches the query, while the "MeSH Term" index searches for those with the MeSH terms that partially match the query.
If one word in front of a matched MeSH term is a chemical token, the MeSH term is treated as a FP annotation.
If two words in front of a matched MeSH term are both chemical tokens, the MeSH term is treated as a FP annotation.
If one word behind a matched MeSH term is a chemical token, the MeSH term is treated as a FP annotation.
Selecting the "MeSHTerm" from the dropdown menu and providing a MeSH term in the search box will retrieve compounds annotated with that MeSH term.
For example, the "MeSH Term Tested" index retrieves assay records in which any tested compound is annotated with the query MeSH term.
Thus, the MeSH term "adenine" is regarded as a false-positive by our MAA program.
False negative (FN) match -- A MeSH term found by manual indexing but not by MAA.
Similarly, references from Western countries were identified from Pubmed using keywords "HIV" (including MesH term "HIV infections"), "neoplasia" (including MesH term "neoplasms") and "epidemiology" (2448 references).
