use Data::Dumper; might give you a clearer picture of whatever data structure you are working with. For example:

However, I do not believe the code you posted is the actual code that you are using. The code you posted would not compile without errors since you have not declared several variables with my, such as @words and @sim.

It is also a good practice to check the success of open, for example: 

open my $in_fh, '<', $Infile or die "Can not open file $Infile: !$\n"
