WebThe method to establish IDF curves is one proposed by Koutsoyiannis in 1998, where the relationship of the IDF curves derives explicitly from the underlying probability distribution function, ... WebThe TF-IDF algorithm is mainly applied to English. Chinese must first be divided into words. After the word segmentation, it must solve the multi-word meaning and the word polysemy. These two problems cannot be solved well by the simple tf-idf method. Then there is a later word embedding method that uses a vector to represent a word.
