We have multiple synonyms for full-form names and their abbreviations like and , or and . What should be the basic form: full length or abbreviated? The labels can be easily swapped.

    $\begingroup$ I think the preferred form should depend on how widespread/well-known the acronym is. E.g. [pca] and [svd] are IMHO fine. But obscure abbreviations are not good as tag names. Where to draw the line, I don't know. $\endgroup$ – amoeba Nov 6 '17 at 15:30

    $\begingroup$ @amoeba but what is "widespread" and "obscure" may depend on your background... $\endgroup$ – Tim Nov 6 '17 at 15:31

    $\begingroup$ OK, but de-abbreviating e.g. [anova] or [arima] seems like an overkill. "Autoregressive integrated moving average" won't even fit as a tag name. $\endgroup$ – amoeba Nov 6 '17 at 15:33

Let the users decide in each case.

When creating synonyms, I have always chosen as the "target" (which is the name that will be displayed) the one most commonly used on the site.

The advantages of this procedure are evident: our tags reflect the values people naturally think of.

The disadvantage would be an apparent inconsistency--sometimes a target would be longer than its synonyms, sometimes shorter. But of what value would such a consistency be? I cannot see any.

    $\begingroup$ +1, this is my default policy as well. $\endgroup$ – gung - Reinstate Monica Nov 6 '17 at 15:55

    $\begingroup$ I don't agree personally, I really prefer the full name be used. Yet, this is a very sensible argument, so I support it. $\endgroup$ – Matthew Drury Nov 6 '17 at 18:11
  • $\begingroup$ @MatthewDrury Would you prefer the full name to be used for "ANOVA"? "ARIMA"? My personal preference would in the vast majority of situations be for full names, but there are a few things which are better-known by their abbreviations. I am upvoting this answer because I suspect, in practice, most of the time that it's sensible, users will prefer fuller names. $\endgroup$ – Silverfish Nov 11 '17 at 23:39

  • $\begingroup$ @Matthew Ah, great post, I've (+1)ed it in the past but forgot it was you who wrote it or that we had discussed it before! It did get a lot of support in that thread, which suggests that many users see abbreviations as (often) unnecessarily ambiguous. $\endgroup$ – Silverfish Nov 12 '17 at 1:22
