Hi!
When I query the Estonian Wikipedia's Web API for the article's first sentence, I sometimes get empty response. Actually it gives back an horizontal rule and thats it.
For example: https://et.wikipedia.org/w/api.php?action=query&prop=extracts%7Ccategori...
gives only an horizontal rule as the extract: "extract": "<hr />",
Can anyone say what is happening here. Is the article's source organized in a wrong way or is it a problem on the APIs sentence parser side?
