As the Internet and computer systems grow in size and complexity, users are having more difficulty finding web objects. Traditional top-down taxonomies are being assisted by the bottom-up approach of folksonomies. This classification system is a result of the aggregation of social tagging in the user’s own language (Vander Wal, 2007). Folksonomies have emerged as a powerful component of the Web 2.0 landscape. This presentation explores the current state of folksonomies.
