Hi, 

I am new to using rapid miner for sentiment analysis/text mining. I watched couple of videos. I used the tokenize, filter, stop words etc. 

 

I have customer id, review date, year of review (Computed from 2nd), customer location (From web scaped data) and the customer review. The field name in Excel is Customer_reviews.When I import the excel, the customer_review comes up as polynomial. 

 

I also get all the positive/negative word list as one word in rapidminer, where as when I look it up in Notepad++, it is all in a separted lines.

 

How do I use the customer_review as a text to arrive at sentiments using postive/negative word list? 

 

Could some one point me the right direction? 

 

Thanks for your time.

 

Ramesh

    Hi there,

     

    I'm trying to use AYLIEN extension to conduct an Aspect-based Sentiment Analysis. 

    There is a parameter called "domain" in which I have to choose between the following options: "cars", "hotels", "airlines" or "restaurants". My question is whether this extension is limited to only those domains. If not, which of them can we use as default?

     

    Thanks in advance.

    Hi Jesus,

     

    the aspect based ones are w.r.t these aspects. Simply choose the generic Extract Sentiment to get a general one.
