Why do you try s/.../identify_year($1)/ge? What is that supposed to do? I thought your objective was to identify a year and the surrounding words?

If you want to know whether there is one or more occurrence of a regular expression, you can use the following idiom: 

my $var = "This is the year 2000.";
my @matches = ($var =~ /([0-9]{4})/g);

The regular expression I gave will only find four digits. You will need to modify that regular expression to also recognize two words before that year and two words after that year.
