Problem Mandarin Text mining - HanMiner

YoGVA

Hi everyone,

I am a newbie here but here is my situation.
I need to conduct a qualitative content analysis of a large number of Chinese reports. However, Rapid Miner needs an extension to capture Chinese characters - I found one called Hanminer posted by another member.

I followed the instructions and installed the extension via Github; but the extension does not show up on RapidMiner ... 

Any ideas to solve that issue? Or another was to text mine Chinese documents?

Any help would be much appreciated!

Hi,

the third party HenMiner Extension has no option to define the encoding of the imported file, as a workaround you could use Macros:

<?xml version="1.0" encoding="UTF-8"?><process version="10.1.002">

hi @YoGVA I'm sorry no one has chimed in here. Is this still an issue?

Hi Scott, 

Yes it is.

I'm trying to install the following but no success so far. 
https /github.com/joeyhaohao/rapidminer-Hanminer
Nothing happens at step 4 when I try to install the extension.

I am also trying to look at other options but it is harder than I expected... 

Any help would be great, cheers!

hi @YoGVA hmm never seen that repo before!

I'm going to cc my good friend and colleague @yyhuang who will know a LOT more about this than I do.

Hi @YoGVA ,

here is a compiled version of the github version, which you can just unzip and copy to .RapidMiner/extension. This works, but i have not tested the operators of course.

Best,

Martin

Thanks for sharing the compiled extension. Dr @mschmitz !
After installing manually by inserting unzipped .jar file into my local extension folder C:\Users\Yy\.RapidMiner\extensions and a restart, everything is working fine. Hi @YoGVA you can follow the instructions here https://community.rapidminer.com/discussion/31996/install-extensions-manually-for-rapidminer-studio


Six new operators added into the new extension folder "Text Miner"

A quick test on the news data looks reasonable.

Hi.

My apologies if I should open a new question. My question is related to the latest version of Hanminer v.1.0.3. I noticed that the READ TEXT operator is now named READ DOCUMENT.

My problem is when I import from file using this operator, the chinese characters became unidentified symbols.






I have tried several ways:
1. I tried using the different encodings listed and have installed chinese character in my windows pc but no difference.





2. I imported the dataset as an example set and used DATA TO DOCUMENTS operator as below. However, I received an error.




3. I tried connecting DATA TO DOCUMENTS operator to the READ DOCUMENT operator but this resulted in wrong input/output connection.



Perhaps, @yyhuang can help shed some light here. Really appreciate it.

Thank you kindly.

Hi,

have you tried to change encoding to UTF-8?

Hi Jonas,

Yes, I have, but still nothing.

Thank you Jonas. That worked fine. Didn't think of macros here.
