Aspect based sentiment analysis

naxiota

Hi guys,

I am quite new to RapidMiner and still long way to go, I have managed to do a sentiment analysis and find some patterns in my texts through association rules; however, my ultimate goal is to operate a sentiment analysis of a specific word in the text, any suggestion on how to do it? Plus, do you think that the process below are correct ? Thanks in advance, cheers.

Hmm, I am not aware of any direct method for this in RapidMiner to be honest.  Most sentiment analyses done with RM focus on the sentiment of the complete document, not on the sentiment of single words...

hi @IngoRM, this is the discussion

I am not sure if I understand this (maybe that is the reason why also nobody else chimed in...).  You mean you want to know how much each word contributes to the sentiment?  Or just in general a sentiment score for single words?  Please explain a bit more and give some examples so that we can understand what exactly you want to achieve.

Cheers,
Ingo

Hi, so I would like to understand the polarity that a newspaper articels have towards a specific words, if it is valued and described as positive or negative in a phrase.

thanks @IngoRM
