The document describes a dataset of over 47,000 bug reports from Eclipse projects and over 168,000 bug reports from Mozilla projects collected between 2006 and 2013. The dataset includes information on 14 attributes for each bug report like bug ID, reporter, product, component, summary, severity and more. It is intended to provide an open dataset for researchers to mine bug information from open source projects.
