In the Web 2.0 environment, users are empowered to collaborate and share information. This has
made the Web more participatory in nature thereby increasing the content creation at a rapid pace.
With this, the ever challenging problem of categorizing content over the Web has increased
tremendously. To combat this, Web 2.0 has one feature known as “Folksonomy”. This allows users to
attach tags to the content so that they can use these tags to retrieve the content in the future.
Folksonomy has pros & cons compared to traditional subject indexing. This paper describes the
fundamental problems inherited to Folksonomy with a case study of user tagging in Social Question
& Answer Platform used within Tata Consultancy Services (TCS).
