Tags that have no questions are automatically deleted every night at midnight, so you can just remove the tag from your question. The privileges page you linked to is talking about tags that exist on only one question -- if after 6 months the tag is still only on that one question, it's assumed to not be a very good tag and gets removed
The answer is in the question you linked:
Try to remove the worst of the worst, then we can remove the tag from the rest en masse.
After 7 months, most of the really bad stuff was gone. Tim Post and I each took a final pass, removing a few hundred questions that'd been overlooked. That done, the tag was burned and blacklisted.
Since you brought it up, ...
You have this backwards, tags are deleted automatically around 24 hours after they have been removed from all questions.
What happens is that moderators or users remove the tag from all questions, not that they delete the tag. That way we can't end up with questions that have no tags.
As Wikipedia reports, segmentation can have more than one meaning, in computing:
segmentation should be replaced from a more appropriate tag, which avoids any ambiguity, such as text-segmentation, for which there are already questions, speech-segmentation, and ...
There's a bunch of questions tagged segmentation which have nothing to do with either images or segmentation faults. In fact, the highest-voted question in the tag is about text processing:
How to split a string into words. Ex: "stringintowords" -> "String Into Words"?
Is there any good open-source or freely available Chinese ...
These tags have no questions attached to them. They will be automatically removed within 24 hours in that case.
If there would be a few questions having these tags, it would be appropriate to retag them correctly. And then the tags will be removed within 24 hours.
The discussion around the burnination of tags is extremely important. What you're suggesting would presumably be like the vote-to-close button, where after some threshold of votes is crossed the tag is automatically burned. This absolutely should not happen.
For a tag to go away somebody should definitely be required to post to Meta indicating why they ...
What seems to have happened is that instead of burninating, it has become a synonym without having to have the usual required community support.
Perhaps it seems that way, cause my UI kind of sucks however I can assure you that Kev, a moderator on Stack Overflow, approved this synonym on the 14th of Jan 2012.
Moderators have binding votes.
They are completely purged from the system; in other words, the full record of the tag is wiped out, and any existence of the tag is also erased from revision histories.
This process can also be done manually by an SE employee to any tag (known as "burninating" a tag), but some communities favor having the community manually edit the tags out of all ...
Someone has already gotten rid of both questions tagged under it, so the tag will go away automatically within 24 hours. The tag wiki excerpt that was suggested has been rejected, as it should be. That tag wiki is completely useless, and their effort would have been better spent retagging the whole two questions that had the improper tag.
However, normally ...
