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

Code

function _nat_node_form_vocabularies_get($form) {

  // Collate taxonomy reference fields by their vocabulary IDs.
  $instances = field_info_instances('node', $form['#node']->type);
  $vocabularies = array();
  foreach ($instances as $name => $instance) {
    if (isset($form[$name])) {
      $field = field_info_field($name);
      if ($field['type'] == 'taxonomy_term_reference') {
        $vocabulary = taxonomy_vocabulary_machine_name_load($field['settings']['allowed_values'][0]['vocabulary']);
        $vocabulary->form_fields[] = $name;
        $vocabularies[$vocabulary->vid] = $vocabulary;
      }
