TAG CLUSTERING APPARATUS BASED ON RELATED TAGS AND TAG CLUSTERING METHOD THEREOF

摘要

PURPOSE: A tag clustering apparatus based on related tags and a tag clustering method thereof are provided to form a tag cluster by gathering tags, thereby overcoming deterioration of a search result. CONSTITUTION: A related tag mapping module(132) extracts and maps related tag pairs each other. A frequency extracting module(134) extracts an appearance frequency of the same tags. A weight matrix generating module(136) generates a weight matrix. A tag clustering module(138) extracts only related tags with a frequency which is larger than a threshold value.
