“I really hate that more people are unimpressed by the lack of low quality of this restaurant”

Is this a positive or negative sentiment statement ?

The mere aggregation of positive and negative expression words is insufficient to determine opinion.
Even hierarchically ranking sentiment words in terms of semantic contribution
to final statement opinion only brings marginal efficacy increases.

Acceptance levels of more than 80% are extremely hard to achieve.

Gatfol applies an innovative and powerful approach to complicated sentiment analysis.

Multiword synonyms iteratively replace groups of statement words
in semantic progression from complication to simplicity:

“I really hate that more people are unimpressed by the lack of low quality of this restaurant”

“I am unhappy that more people are unhappy with the quality”

“I want less people to be unhappy with the quality”

“I want more people to be happy with the quality”

“I am happy with the quality”

 
Even though almost all of the original sentiment phrase words are negative –
through Gatfol simplification iteration – the final sentiment result is positive.
