# RRVGO
Reduce and visualize lists of Gene Ontology terms by identifying redudance based on semantic similarity.
## Introduction to rrvgo
Gene Ontologies (GO) are often used to guide the interpretation of high-throughput
omics experiments, with lists of differentially regulated genes being summarized
into sets of genes with a common functional representation. Due to the hierachical
nature of Gene Ontologies, the resulting lists of enriched sets are usually
redundant and difficult to interpret.
`rrvgo` aims at simplifying the redundance of GO sets by grouping similar terms
in terms of semantic similarity. It also provides some plots to help with
interpreting the summarized terms.
This software is heavily influenced by [REVIGO](http://revigo.irb.hr/). It mimics
a good part of its core functionality, and even some of the outputs are similar.
Without aims to compete, `rrvgo` tries to offer a programatic interface using
available annotation databases and semantic similarity methods implemented in the
Bioconductor project.
