Dear monks

I need some help in adapting the following Regex:

my ($rx) = map qr/(?:$_)/, join "|", map qr/\b\Q$_\E\b/, @stopwords;

[download]

which I use to remove from a string all stopwords contained in @stopwords by means of $string =~ s/$rx//g;. This works fine except for the cases that a word contains a hyphen and one part of the word happens to be a stop word. So for example, the French word "sous-alimentation" looses "sous" (being "sous" in my @stowords), even if it should retain it as being part of a terminological unit. Any idea how can I avoid it? (I thought to use whitespaces in my $rx, but I guess they could cause problems at the beginning and end of the string). Thank you.
