  1. In the navigation pane of Prediction Studio, click Models.

  2. In the header of the Models work area, click New Text categorization .

  3. In the New text categorization model window, set up the new model:

    1. In the Name field, enter a name for the topic detection model.

    2. In the Language list, select a language for the model to use.

      For more information, see Language support for NLP.
    3. In the What do you want to detect? section, click Topics, and then select the Use machine learning check box.

    4. In the Save model section, specify the class in which you want to save the model, and then specify its ruleset or branch.

Define the taxonomy that you want to use for topic detection. For more information, see Defining a taxonomy for machine learning topic detection.

  • Creating machine-learning topic detection models

    Efficiently connect your customers with the right consultant by providing training data to a topic detection model.

  • Detecting the topics of text fragments

    Efficiently categorize and rout customer inquiries to the corresponding customer service consultant with topic detection. Topic detection scans a piece of text and determines the underlying topic, and then automatically assigns the text to a predefined category.

  • Analyzing natural language

    Effortlessly analyze and extract meaningful information from large volumes of text with the use of text analytics. Based on your findings, you can further improve business performance and customer experience.

  • Text analytics accuracy measures

    Models predict an outcome, which might or might not match the actual outcome. The following measures are used to examine the performance of text analytics models. When you create a sentiment or classification model, you can analyze the results by using the performance measures that are described below.
