IC_Seddiqui_2010(
dag,
use_cache = simona_opt$use_cache,
verbose = simona_opt$verbose
)It is also a correction to IC_Seco_2004, but considers number of relations connecting a term (i.e. number of parent terms and child terms). The information content is defined as:
(1-sigma)*IC_Seco + sigma*log((n_parents + n_children + 1)/log((total_edges + 1))where n_parents and n_children are the numbers of parents and children of term t. The tuning factor sigma is defined as
sigma = log(total_edges+1)/(log(total_edges) + log(total_terms))where total_edges is the number of all relations (all parent-child relations)
and total_terms is the number of all terms in the DAG.
