Sentiment analysis of text with own dictionary (SentiWS)
I am trying to do a sentiment analysis of a huge set of data (all in Excel, news on daily basis: column 1 = date, column 2 = headline, column 3 = text). Additionally to that I have a dictionary (SentiWS) with words and weighting for each word (excel file aswell).
What I have done so far: Importing the dictionary (Read Excel), (Data to Documents), (Processing Documents) - this provides me with a list of words and their weighting.
Furthermore I know how to tokenize the text from the daily news, but how can I compare the tokens from the news and the words from my dictionary, so that I can tell wheather one news is positive or negative?
Thanks for replies
