WebText and Document Feature Extraction. Text feature extraction and pre-processing for classification algorithms are very significant. In this section, we start to talk about text cleaning since most of documents contain a lot of noise. In this part, we discuss two primary methods of text feature extractions- word embedding and weighted word. WebThis method creates the vocabulary index based on word frequency. So if you give it something like, "The cat sat on the mat." It will create a dictionary s.t. word_index ["the"] = 1; word_index ["cat"] = 2 it is word -> index dictionary so every word gets a unique integer value. 0 is reserved for padding.
