JimmyTheSaint said:If it can be reduced to a straightforward batch string-search-and-replace from a reference list of alternative spellings, then it's quite fair to ask for consistency of spelling convention--whether British or American--within each dictionary. Mike, however, says it's too labor intensive to be cost effective. But it's sloppy. It's easy enough for the average customer to get used to overlooking it, unfortunately, but with language professionals, such inconsistency reflects badly on the product. When's the last time you saw a published text with mixed British/American spelling conventions?
Have you spent a lot of time with printed Chinese-English dictionaries? A great many of them have similar errors - these errors in PLC come entirely from the printed title we licensed to base it on, so you're asking us to fix errors in that printed text rather than errors that we made ourselves. Dictionaries are simply too big and low-margin for everything to be perfect - even the OED has the occasional embarrassing glitch.
I do agree that we ought to do something to straighten this out for full-text searching - not hard, we'd just build a little list of British and American spellings into our app and automatically search on both when you type in either one - but with all of the other editorial projects we're working on it's very hard to justify going through and rewriting every entry to use the same spelling; that's time we could be using to, say, clean up one of our not-so-nicely-formatted dictionaries (like 21C), or for that matter to adapt a newly-licensed dictionary. Even in PLC specifically, the time might be better put towards updating some outdated example sentences, or adding entries for some more of the thousands of missing words people have reported to us. Mixed British and American spelling might look sloppy, but not having an entry for 超市 (as we didn't until last summer) or having an example sentence with embarrassing 70s-era political rhetoric in it (as we still have quite a number of) looks considerably sloppier.
