6 Myths of Sentiment Validity

1) You can tell how valid a sentiment scoring system is by evaluating as few as 20 records
2) You can accurately judge validity by examining the originally assigned score and deciding if you agree with it
3) If data for one brand is valid, data for all the brands are probably valid as well
4) You can judge validity by checking twitter data as it is the lowest common denominator
5) If the system is based on natural language processing, you know the sentiment is valid
6) If the sentiment scoring is manual, you know it’s perfectly valid.
