I'm ignorant. I thought "bag of words" was a representation (the idea that a sentence has no grammar, it's just represented by its words as columns, maybe weighted by tf-idf who knows), not a specific model.
Where can I read about this bag of words?
Where can I read about this bag of words?
Also: a vector space is a set of things that can be added and multiplied by a scalar. So a vector space model should be the proverbial representation where "queen - woman + man = king".
Am I being an insufferable pedant? I follow text analysis only very lightly and keep losing the thread.
The queen - woman example is when you try to make a model of word semantics, such as with word2vec. In a document classification task the vectors represent documents.
