The document discusses folksonomies, social tagging, and Web 2.0 tools. It defines folksonomies as user-generated categorization of web content using tags. It describes how folksonomies make information easier to search and navigate over time. It also discusses the differences between folksonomies and formal taxonomies, and provides examples of Web 2.0 tools like tagging, bookmarking, and social media platforms that enable folksonomies and user interaction.
