Study on Social Tag Relevance Judgment Based on Relative Frequency

  Tag relevance judgment is the foundation of tag application research and practice.Currently, tag relevance judgment strategies meet some problems in experiment effect and universality.To ameliorate both the effect and generalization of social tag relevance judgment strategies, this paper proposes a tag relevance judgment algorithm based on relative frequency.We verify this strategy by experiment based on 675 351 Douban Movie users social tagging data.The results show that the effect of tag relevance judgment for tags whose frequencies are at least 5 performs well, for the recall is 84.16% and precision is 90.77%.We compare this strategy to the Top-N social tag relevance judgment strategy, and the result is obviously better than the Top-N strategy.Moreover, this strategy has good universality.It is suitable for various media such as video, audio, txt, image etc.Thus, it can be concluded that this strategy can solve tag relevance judgment problem well.
