How to classify abstract of a given research article into a pre-specified category using SVM?

My intention is to assign a certain article into a pre-specified group based on the abstract. How this can be done using a support vector machine?

    Normally, you'd have to parse the abstracts using "Process Documents from ..." (either from Files or Data, easier from data as you'd have the classification label in the example), then possibly reduce the number of generated attributes (e.g. you could use SVD or PCA or with weigh-select method), and then develop your classifier. SVM is not an easy way of doing this as you'd have to select and optimise the kernel, e.g. using "Optimize Parameters (Grid)", so if you want a quick answer, first try another classifier or their ensemble, e.g. GBT. Of course, always (cross-)validate your model.
