RapidMiner 9.8 continues to innovate in data science collaboration, connectivity and governance
I'm working with Rapid miner with the goal of preprocessing texts (I want to start from the text and I want to obtain a matrix where the rows are my texts and the columns are the features). I feed the process with a folder containing all my texts and I want to be sure of a detail: which is the order in which they're stored in the final matrix?
Suppose my folder contains:
in the matrix I'll have three rows
1 -> a.txt
2 -> b.txt
3 -> c.txt
Is this correct? and so am I sure that the rows of my matrix will correspond exactly to the documents in alphabetical order?
Thnks for your cooperation
