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… -

Re: Term frequency from Excel file
It would be much better to post the actual process and data, since very little can be learned from the pictures. For example, you have an operator labeled "Generate TF-IDF" but I have no idea what it is or what it is doing, since generating the TF-IDF vector is automatically part of the output (if selected) from Process… -
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… -
Re: Parsing attributes
Word2vec is available from Marketplace. https://marketplace.rapidminer.com/UpdateServer/faces/product_details.xhtml?productId=rmx_word2vec But I do not think word2vec is necessary. TF-Idf may be enough for phrase recognition. Just define a list of strings for the target categories, then use it as the wordlist input for… -
