The results listed in the article's infobox look impressive, but I have no idea what world championships she was competing in.  The recognized world championships by the International Judo Federation do not match the years and locations given nor is she listed among the 139,000 judoka at judoinside.com .  There is also no mention of her at the IBJJF website, which includes results of all IBJJF world championships.  Some reporting of results, especially local coverage, doesn't make the case for meeting .  I'm not voting yet, so that additional supporting evidence for her notability can be presented
