Since we are discussing segmentation at the Keyboard Maestro forum, I was wondering whether someone can provide an algorithm for segmentation? E.g. in VBA, basic, AppleScript etc.

Core Foundation and Cocoa on MacOS. Not very portable, but it illustrates the general approach: An object that slices up a string based on delimiters (in this case built into CFStringTokenizer). This should work across many languages and writing systems. If locale was irrelevant we wouldn't need the tokenizer and could reduce the code to one line or a couple of lines.

NSMutableArray<NSString*>* sentences = [NSMutableArray array];
CFLocaleRef locale = CFLocaleCopyCurrent ... See more

CFStringTokenizerRef tokenizer = CFStringTokenizerCreate(kCFAllocatorDefault, (__bridge CFStringRef) aStr, CFRangeMake(0, aStr.length), kCFStringTokenizerUnitSentence, locale);

for(;;)
{
CFStringTokenizerTokenType tokenType = CFStringTokenizerAdvanceToNextToken (tokenizer);

if(tokenType != kCFStringTokenizerTokenNone)
{
CFRange cfr = CFStringTokenizerGetCurrentTokenRange (tokenizer);

[sentences addObject:[aStr substringWithRange:NSMakeRange(cfr.location, cfr.length)]];
}
else
{
break;
}
}

CFRelease(tokenizer);
CFRelease(locale);
