摘要: | 預測網路標籤趨勢 Popular social bookmark service del.icio.us enables easy annotation for user to orga- nize their resources. The lightweight conceptual structure built by users called folkson- omy is able to provide a di?erent retrieval service that utilzes its power. However, the performance was hindered by lack of tags at a resource’s new arrival. Thus, our work aims to overcome the handicap of retreival for new-coming URLs by predicting tags at early stage. We exploit accumulated tagging records from users to predict tags. Our experiements on del.icio.us URLs show that our algorithm has a high coverage of tags appearing in the mature stage. Our prediction captures 80% of a 13-month old tag set at the first month and 80.23% of 100-users tag set with 5-users tag set. |
