Social tagging is a collaborative information-organizing practice in which users assign freely chosen keywords, or tags, to digital resources such as webpages, images, publications, and videos [1][2]. Unlike traditional classification systems based on predefined categories, social tagging allows users to describe content according to their own interests, interpretations, and information needs. When tags are shared and aggregated across users, they form a collectively generated classification structure, commonly known as a folksonomy [3]. Social tagging supports resource discovery, browsing, and knowledge sharing by connecting content through user-generated labels. However, differences in terminology, ambiguity, and inconsistent tagging practices can affect retrieval accuracy [4].
