#!/usr/bin/env perl

use strict;

my $VAR1 = ... your posted data here ...;

my @records = @$VAR1;

for my $index (0 .. $#{$records[0]}) {
    print "$records[0][$index][1] -> $records[0][$index][0]\n";

Output:

Science | -> Sciences |
Research | -> Recherche |
Artificial Intelligence -> Intelligence artificielle

So, that gets the job done. With a better understanding of the data you start with, I expect that could probably be greatly simplified.

Using the same name (i.e. decoded_json) for both a scalar and an array variable has a high chance of tripping you up somewhere in the code. You show Dumper $record in your posted code but later you say "Dump was of \@records".

I'm also getting the sense that you're not overly familiar with handling arrays and arrayrefs. Take a look at perlintro; its "Perl variable types" section; the "Arrays" subsection; then follow the "Exhaustive information ..." links at the end (i.e. right before the "Variable scoping" heading).
