I'm trying to figure out a way I could represent a Facebook user as a vector. I decided to go with stacking the different attributes/parameters of the user into one big vector (i.e. age is a vector of size 100, where 100 is the maximum age you can have, if you are lets say 50, the first 50 values of the vector would be 1 just like a thermometer).
Now I want to represent the Facebook interests as a vector too, and I just can't figure out a way. They are a collection of words and the space that represents all the words is huge, I can't go for a model like a bag of words or something similar. How should I proceed? I'm still new to this, any reference would be highly appreciated.
