In the field of machine learning, many problems are treated as classification tasks. A classifier takes an event and assigns a (pre-defined) class to it. When events are sequences, the classification may be based on aspects of the structure of these events. For instance, the fact that certain symbols co-occur in a sequence may be an indication that these sequences belong to a certain class.

In this talk, I will describe some research I have been doing in this field recently. This work is still in progress. I will show some results on the task of question classification (assign the type of answer to a question), and composer classification (given a musical piece, assign its composer).
