TFIDF-master
tf–idf, short for term frequency–inverse document frequency, is a numerical statistic that is intended to reflect how important a word is to a document in a collection or corpus.[1]:8 It is often used as a weighting factor in information retrieval and text mining. The tf-idf value increases proportionally to the number of times a word appears in the document, but is offset by the frequency of the word in the corpus, which helps to control for the fact that some words are generally more common than others.
Variations of the tf–idf weighting scheme are often used by search engines as a central tool in scoring and ranking a document s relevance given a user query. tf–idf can be successfully used for stop-words filtering in various subject fields including text summarization and classification.
One of the simplest ranking functions is computed by summing the tf–idf for each query term many more sophisticated ranking functions are variants of this simple model.

计算tec（tokyo）
Estimate tec (total electron content) by least-sqaure adjustment using GPS
dual-frequency code observables. Ionosphere is approximated as the single-
layer model at the height of 350km with local or global tec model.
Satellite/receiver dcbs (differential code biases) are estimated as well
as tec model coefficients.
