Spam filtering has become a very important issue throughout the last years as unsolicited bulk e-mail imposes large problems in terms of both the amount of time spent on and the resources needed to automatically filter those messages. Text information retrieval offers the tools and algorithms to handle text documents in their data vector form. Thereon, machine learning algorithms can be applied. This paper deals with the possible improvements gained from ensembles, i.e. multiple, differing classifiers for the same task. Those individual classifiers can fit parts of the training data better and therefore may improve classification results, when the best fitting classifier can be found. Basic classification algorithms as well as clustering are introduced.
