Currently I am working with Text Mining which includes sentiment identification and assigning corresponding business categories using open source tool R. I found these two documents which helped me to some extent:
My approach is to tokenize the text and then lookup for sentiment and business category. To do this I require positive and negative libraries for sentiment mining and category file which contains word and category. I was able to get positive and negative words but was unable to get a categorization library.
- Where can I get a categorization library?
- Is the above approach appropriate? Is there a better way to do this?
