• The benchmark contains annotations of both named entities as well as other types of entities, annotated on different types of text, ranging from clean text taken from Wikipedia, to noisy spoken data.
• The benchmark was built through a highly controlled crowd sourcing process to ensure its quality.
• We describe the benchmark, the process and the guidelines that were used to build it.
