MPQA Corpus

[raj.shah]

Hi,

I am new on KNIME and trying to build workflow around sentiment analytics.

How do I get MPQA corpus files (positive and negative) to ingest into file reader?

Thanks,

Raj

Hi Raj,

please see:

http://mpqa.cs.pitt.edu/ and http://mpqa.cs.pitt.edu/lexicons/subj_lexicon/

to download the dictionaries. To extract the information in these files in order to get a proper dictionary that can be used in KNIME afterwards, you need a bit of string preprocessing.

Find attached to this post the two preprocessed mpqa files. To read these files simply use the File Reader.

Cheers, Kilian
