# How to Train on plain text paragraphs and return keyphrases? is that even possible?

I am working on keyphrase extraction. Right now, I was able to create some features and run the candidate phrases along with the features for training a machine learning model for classification using random forest.

Now, out of curiosity, I would like to try out deep learning. I would like to remove the layer of feature extraction manually and then have it figure out the features by itself. Then generate a model by just passing some text documents and the relative key phrases (1/0 whether correct or incorrect) for each document. My question, does any training model accept plain text instead of floating point values? If not, how do I achieve the same thing by converting the sentences and keyphrases into floating point values and then pass through the trained model?

I tried creating a model using Keras Sequential model (sample given):

model = Sequential()
