I just discovered that was sometimes being used when should be used.

In order to find questions where it was mis-used, I looked for questions tagged with , and eliminated questions with other tags indicating that it was used correctly (generally SQL related). I ended up with a query of

[case-when] -[sql] -[tsql] -[sql-server] -[hql] -[mysql] -[oracle] -[sql-server-2008] -[sql-server-2005] -[sybase] -[jpql]

is there a more efficient way of finding questions that have been mistagged with a given ambiguous tag?

I'm envisaging something that looks at all the questions tagged with , evaluates how similar each question is with each other question, and manages to work out that there's there's two groups of questions, where questions within a group are similar to each other but questions in one group are fairly different to questions in the other group.


I am trying to retag questions where case-when was used but it should have been switch-statement. Also, I wouldn't envisage the tool doing the retagging, just provide me with a list of questions that probably should be retagged.

I'm sorry but I don't follow that last paragraph. Are you trying to retag all case-when questions? –  Asad Jan 10 '13 at 4:05
    
@Asad Just the questions were case-when was used but it should have been switch-statement. Also, I wouldn't envisage the tool doing the retagging, just provide me with a list of questions that probably should be retagged. –  Andrew Grimm Jan 10 '13 at 4:16
