function get_tags_arr($title)
{
require(APP_ROOT.'/pscws4.class.php');
$pscws = new PSCWS4();
$pscws->set_dict(APP_ROOT.'/scws/dict.utf8.xdb');
$pscws->set_rule(APP_ROOT.'/scws/rules.utf8.ini');
$pscws->set_ignore(true);
$pscws->send_text($title);
$words = $pscws->get_tops(5);
$tags = array();
foreach ($words as $val) {
$tags[] = $val['word'];
