[Purpose/significance] Tag quality is often related to users' experience of classification, query, browsing, acquisition of online resources in social tagging system. Identifying key influencing factors of tag quality can optimize the core functions of resources organization of STS.[Method/process] Based on tags, we provided the influencing factors model of tag quality from six perspectives, which covered tagging subject, tagging object, tagging environment, tagging motivation, tagging methods and tagging products. The study attempted to explore the key influencing factors of tag quality by questionnaire, and established the decision tree model of influencing factors of tag quality based on Random Forest.[Result/conclusion] Tagging subject is the primary key dimension affecting tag quality. And the impact of the subject's knowledge structure and cognitive level, the subject's tagging frequency, and the subject's perceived usefulness are prominent. Tagging methods are the secondary one, and tag recommendation and standard tag tips are main influencing factors.
