Dear Sir,
What is the acceptance level of Jaccard coefficient? Is there any minimum limit up to which the correlation is valid?
There is no explicit / external limit, I think. It will vary depending on the structure of your data.
Roughly speaking, it is around 0.1 in my experience.
BTW, Jaccard coef. is not a KH Coder spesific topic. For more detailed technical explanations, I recommend you consult books on statistics.

Thank you sir for valuable insights.
What does the colors indicate in co-occurrence network figure.
What is the difference between text mining and bibliometric analysis ?
Check page 12 of the quick start tutorial:

When you select "Community" options, different colors mean different communities. That's all.
Well, I am not sure. The definition of "text mining" is not very clear. It appears to me that "text mining" is a marketing term rather than an academic term.
I think these two use same or very similar statistical methods. But the purpose and / or philosophy of the analysis may vary.
