Algorithms

Explanation:

• Robots are controlled by algorithms that can be programmed with keywords to search for.
• The algorithm can be taught to consider a review good or bad based on the presence of specific keywords and combinations of words in the review.
• Of course, it isn't a flawless process, but robots do it correctly the vast majority of the time, with a very little margin of error.
• It can basically differentiate:

1. by putting the review text through a clustering technique
2. by putting the review text through a binary classification method
3. by analysing the review text using entity recognition algorithms
