Issue With Loop Files Operator
I'm new to the forum and RapidMiner so excuse any redundancies or lack of details.
I am working with the process from Chapter 14 (Robust Language Identification) of RapidMiner: Data Maning Use Cases and Business Analytics Applications published by CRC press. The process was downloaded from here: http://rapidminerbook.com/index.php/chapter-downloads-13-24/chapter-14/
attachment 1 shows a screenshot of the process and attachment 2 of the loop files sub-process
I successfully loaded the process, and downloaded the language corpora from http://corpora.informatik.uni-leipzig.de/download.html
I changed the directory for the loop files operator to read from the folder where the corpora is stored. There are five files in the directory (german, english, french, portugese and spanish). the loop files operator seems to be sucessfully reading all of them, but gives a 6th output which seems nonsensical. attachment 3 shows the expected output for any language file (enlgish in this case). attachment 3 shows the nonsensical output. Attachment 5 shows the error thrown, presumably by the nonsense output. Could someone tell me why it's happening and how to fix it? Thanks!
