Vocabulary and interactive tools Definition
Concepts Biological words or phrases (e.g., inflammation, oxidative stress, and hydrogen peroxide) found in this topic-specific literature, organized into thematic dictionaries, and used to mine the literature
Concept Pairs Cooccurring “Enriched Concepts” (e.g., cell fate determination and TAL1; Wnt receptor and CELSR2; and BMP2K and coronary artery endothelial cell) that may or may not have a biological association/connection
FDR “To be enriched, a concept or a pair has to have an FDR (false discovery rate) < 0.05 in the DES-RedoxVasc corpus. The FDR is obtained by correcting the enrichment P values for multiplicity testing based on the Benjamini-Hochberg procedure”
