On this page poll widget also is target of article and also has a meta-tag [@property="article:tag" and @content="poll"]

Now I will give below an example where the survey is not the purpose of the article and it does not contain meta tag [@property="article:tag" and @content="poll"]

Resume:
In first and second cases poll is target of article and IV should not be generated.
In third case poll widget should be removed.
All this can be identified by a meta tag.
