Categorizing reviews/evaluations

With the use of Natural Language Processing (NLP), robots extract hidden senses and meaning from unstructured content, i.e., for example, conduct sentiment research (i.e., the emotional nature of a message). Companies (including Booking.com) use this solution to analyze customer reviews posted online efficiently. For example, the software can assess whether, in essence, they are positive, neutral, or negative. In the latter case, a warning is sent so that immediate intervention can be carried out.
