摘要內容：
Data deluge has created the Big Data Era. How to extract generalizable knowledge from data has attracted people’s attention from many research areas, industrial and business domains. In this talk, we will give a brief introduction to Big Data from data analytics point of view and demonstrate one of its applications, malicious URLs filtering that comes from information security industry. We present a novel lightweight filter to use before existing processing methods based only on the URL string itself. We run experiments on a large dataset and demonstrate a 75% reduction in workload size while retaining at least 90% of malicious URLs. Existing methods do not scale well with the hundreds of millions of URLs encountered every day as the problem is a heavily imbalanced large scale binary classification problem. Our proposed method is able to handle near two millions URLs less than five minutes. Our filter can significantly reduce the volume of URL queries on which further analysis need be performed, saving both computing time and bandwidth used for content retrieval.
