The service offers a wide range of insights:

  • Sentiment scoring: Raw text is analyzed for indications of positive and negative feelings.
  • Topic detection: Key terms are automatically extracted from the text so that the key points are quickly identified.
  • Available taxonomies: Automotive, Banking, Energy, Healthcare, Health Insurance, Insurance, Municipalities, Pension, Publisher, Retail, Telecom. There are always new branches in development.

Insights:

  • The employees were friendly. The waiting time was very long.
  • Topic: Attitude & behavior employee.
  • Subtopic: Kindness.
  • Explanation: Kindness is assigned because:
    • The first sentence is given higher priority.
    • Friendliness from driver modeling and existing theories appear to have a major influence on customer satisfaction.

With long texts, topics mentioned in the first sentences are given higher priority than topics mentioned later in the text. In texts with multiple topics per sentence, the algorithm prioritizes based on the frequency and the effect the aspects have on customer satisfaction and loyalty. This effect has been established based on driver models developed in-house and existing theories such as Noriaki Kano's three-factor theory. 

Scientifically proven

The Text Mining API is developed together with leading universities. Hence, the API is scientifically based and the reliability is high. Furthermore, the models the API uses are continually trained.

SNS: a satisfied customer     

SNS has a couple of strategic themes. Customer retention is one of them. Within this theme, achieving a positive NPS is an important objective. To accomplish this, SNS needed to get more insight into the NPS feedback. By using text mining, SNS was able to find clear indicators for starting the prioritizing process for improving the customer experience, which in turn, helped to increase the NPS.
