Term Frequencies and TF-IDF: How are these calculated?
Term Frequencies and TF-IDF: How are these calculated? Are you are like me – using "Process Documents" for a long time but never truly understood what those numbers are? Or perhaps just a math geek who enjoys vector analysis? Either way, relax for a moment while I walk you through a step-by-step example of exactly how… -

interpreting the sum of TF-IDF scores of words across documents
hi guys! after doing a clustering on a list of documents with the k-means, I would like to analyze the words in each cluster (in order to correlate them with other attributes). About this I added up the value of tf-idf for each words, but I think that this solution can be wrong. Could it be more correct to use term… -
Term Frequencies greater than 1
Dear all, I use "Text Processing - Process Documents From Files" to calculate word vectors for documents. As I read here: http://rapid-i.com/rapidforum/index.php?PHPSESSID=0aba344304fbb94614ad24f236d974e4&;topic=3728.0 term frequencies are normalized (as I expected). For me this means that term frequencies always have… -

A question about naive bayes based text classification
Hi, I am testing the naive bayes(NB) for text classification. To my understanding, the result should not be affected by the tf-idf vector of the text. Because NB considers the frequency of each term(t) in each category(c), i.e., p(t | c), and this information is stored in WordList, not the term vectors(i.e., the…
