NAT - node auto term - is a helper module that automatically creates a term using the same title as a node.

Code

function _nat_get_term_hierarchies($node) {

  // Collate taxonomy reference fields by their vocabulary IDs.
  $instances = field_info_instances('node', $node->type);
  $hierarchy = array();
  foreach ($instances as $name => $instance) {
    if (isset($node->{$name})) {
      $field = field_info_field($name);
      if ($field['type'] == 'taxonomy_term_reference' && !empty($node->{$name})) {
        $vocabulary = taxonomy_vocabulary_machine_name_load($field['settings']['allowed_values'][0]['vocabulary']);
        $terms = field_get_items('node', $node, $name, $node->language);
        foreach ($terms as $term) {
          $hierarchy[$vocabulary->vid][] = $term['tid'];
        }
      }
    }
  }
  return $hierarchy;
