You can assign numerical data to you text and then do SVM. Once you have output you need to reverse to text. MI works on maths

SVM is an supervised learning algorithm or concept used for classification and regression analysis. The implementation can be done for any numeric data, text data, symbols or images. The logic is to find the implementation of hyper plane for separation and the support vectors.

Yes, you can use textual data in SVM, but you need to turn the text content into numerical feature vectors e.g. using bag of words or occurrence of frequencies. http://scikit-learn.org/stable/tutorial/text_analytics/working_with_text_data.html

SVM can work with textual data also. However you have to train the SVM to classify the text data. It is a usual practice to create a document-term matrix from the text that you have, to make SVM work easily on the data.

SVMs work with numerical data only - needs to be a vector input. But you can transform textual data into word vectors so that we can use SVM on textual data. Some of the methods are TFIDF, word2Vec, GloVe and FastText.

First of all, not sure what you mean by textual data. Do you mean text classification or categorical variable. Anyway, SVM works well with both. I have used it for text classification also, and found it to consistently provide the very high rate of accurate classifiers. Using the Sequential Minimal Optimization... read more

Using the Sequential Minimal Optimization (SMO) methods, learning the SVM model is very fast. read less

I think it is applicable for numeric data since it is based on categorized prediction.
