The camera-ready version of the ECIR papers, A Framework for Unsupervised Spam Detection in Social Networking Sites (with Maarten Bosma and Wouter Weerkamp) and Adaptive Temporal Query Modeling (with Hendrike Peetz, Wouter Weerkamp, and Maarten de Rijke) are available now.
In the first paper, we report on the effectiveness of an unsupervised spam detection method for community-based websites, where users can indicate whether messages posted by others are spam. The collection of the user-generated messages that we used, their spam reports, and labels will be released soon, stay tuned.
