GiveALink Tagging Game: An Incentive for Social Annotation

摘要

Social tagging systems lead to inferred relationships among resources, tags and users from shared annotations in support of applications such as search, recommendation, and navigation. However, users share annotations largely for their own individual needs, such as bookmarking and involvement in online communities. Free tagging may also result in low-quality annotation data. In this paper, we introduce a tagging game designed as an incentive for users to share a large number of high-quality social annotation data while being entertained. Preliminary results suggest that playing the game leads users to classify resources into broad categories.
