Topics are the key to understanding your customer’s satisfaction by automatically labeling and categorizing incoming written feedback.



  • Clustering and analysis of feedback is fully automated

  • Easily see and filter for particular Topics

  • Prioritize Topics based on how often they appear

  • Track the NPS development per Topic

  • Direct feedback to the right people in your organization

The Topics Processing Flow

  1. Language detection → The comment’s language is detected for further processing and labeling.

  2. Parser → The comment is checked for grammar and analyzed for meaning. In other words, the parser digests the comment and extracts the message

  3. Stopwords are removed → AI removes unnecessary stopwords (aka filler words) but only to a degree that ensures the meaning of the comment is kept

  4. Stemmer → The stemmer further simplifies the comment by bringing the words to their base form. For example, delivery or delivered becomes deliver

  5. Keyword matching → The keywords from your Topic Dictionary are matched to the keywords in the comment

  6. Labeling → When matched keywords are identified, the comment is labeled with the Topic

  7. Sentiment Analysis → Once the labels are assigned, the AI checks the comment for mood and tonality. In other words, it will detect whether a statement about a Topic is negative, positive or neutral.

Topic Sentiment

The sentiments of Topics indicate how your customers feel about each individual Topic within the comment.

The Topics can carry a positive, negative or neutral sentiment.
