Analytics with RapidMiner + Rosette [getting started]

Hi,

I'm just getting started with RM for text analytics. Everything has gone well working with structured data but I'm struggling with analysing text documents. Could you anyone provide a process of how to extract entities from a PDF or Word Doc? 

 

I've searched these forums and Google and the only solution that seems to work is converting the file into a txt file first, which isn't ideal.

 

Any help would be super appreciated.

I am afraid that converting the files first is the easiest option available to you with existing operators.  Another option would be to import your document text into a database first using a database program like MySQL and then use "Read Database."  But RapidMiner won't read Word Docs or PDF text directly.

Hi...you can extract the text from PDFs no problem with the Read Document operator.  It will lose all formatting but very easy to do.  If you want to pull structured data from a table inside a PDF, there is the new "PDF Table Extraction" extension which is rather good.

 

As for docx, what I do is send the file to a converter API engine (like Zamzar or Convertio) and convert it to text, then import.

Hi Scott,

I'm guessing it depends on what's in the specific file. All I get from using the read document operator is non-sensical text in a font I can't make out.
