Stats of how many papers have abstracts and full papers(oa_url links) successfully available /

[Purna Srivatsa]

Some papers don't have anything meaningful in abstract.

And some papers dont lead to a meaningful place from the oa_url link. 

Are there stats on how successful the paper data processing is performing across the papers ? So there's visibility into how many papers are available as more than just a search result and how many are yet to be successfully processed ?

Thanks for the help,
