Hello @Hamidah,

You can use read document operator in "Text Processing" Toolbox to read pdf files. You need to install this from the marketplace in rapidminer (Extensions --> Market Place).

Here is a link related to the similar discussion.

Hi @Hamidah,

Have you tried Text Processing extension from RapidMiner maketplace?



Using "Read document" you can extract the text from a pdf file.

<?xml version="1.0" encoding="UTF-8"?><process version="9.3.001">

    <input/>
    <output/>
    <macros/>
