i've produced publish type and also the custom taxonomy of this publish.

register_post_type( "expertise", array( 'label'             => 'Expertise',
    'labels'            => array(   'name'                  =>  'Expertise',
                                    'singular_name'         =>  'Expertise',
                                    'add_new'               =>  'Add New Expertise',
                                    'add_new_item'          =>  'Add New Expertise',
                                    'edit'                  =>  'Edit Expertise',
                                    'edit_item'             =>  'Edit Expertise',
                                    'new_item'              =>  'New Expertise',
                                    'view_item'             =>  'View Expertise',
                                    'search_items'          =>  'Search Expertise',
                                    'not_found'             =>  'Not found any Expertise',
                                    'not_found_in_trash'    =>  'No Expertisews Thrash' ),
    'public'            => true,
    'can_export'        => true,
    'show_ui'           => true, // UI in admin panel
    '_builtin'          => false, // It's a custom post type, not built in
    '_edit_link'        => 'post.php?post_type=expertise&post=%d',
    'capability_type'   => 'post',
    'menu_icon'         => '',
    'hierarchical'      => false,
    'rewrite'           => array("slug" => "expertise"), // Permalinks
    'query_var'         => "expertise", // This goes to the WP_Query schema
    'supports'          => array('title','category') ,
    'show_in_nav_menus' => true
));
register_taxonomy("expertisecat", array("expertise"), array("hierarchical" => true, "label" => "Expertise Category", "singular_label" => "Expertise Category", "rewrite" => true));
