Text Classification is MeaningCloud's solution for automated document classification. It assigns one or more categories to a text, using standard domain-specific taxonomies (e.g., IPTC. IAB, ICD-10) or user-defined categories. The algorithm combines statistical document classification with rule-based filtering, which allows to obtain a high degree of accuracy and flexibility in a wide range of environments.


  • Statistical classifiers provide a means to use example documents to define each category.
  • In turn, rule base classifiers helps to fine-tune the classification and correct the output of statistical classifiers.
  • Its powerful rule based classification language is also useful to bootstrap a categorization when no examples are available.
  • Features predefined, standard taxonomies: IPTC, IAB, ICD-10, Eurovoc.
  • User can create his/her own categories and classification models.
