2011年9月23日上午，澳大利亚维多利亚大学研究员徐贯东博士应邀访问中国科学技术大学计算机学院，并在学院学术报告厅作题为“SemRec: A Semantic Enhancement Framework for Tag based Recommendation”的学术报告。报告会由陈恩红副院长主持。
徐贯东博士主要介绍了一种基于结构信息和语义信息的模糊模型，进而提出一种语义加强推荐的策略，用于现有的标签推荐系统中。对于该模糊模型存在的潜在问题以及实验中存在的问题，徐贯东博士和与会的师生进行了深入探讨，取得了良好的交流效果。
报告会结束后，徐贯东博士与学院师生进行了进一步的讨论和交流，并希望今后能与学院开展更多的合作。
