    Build Training Data Jobs

    Table of Contents

    Use this job to build training data for query classification by joining signals data with catalog data.

    The output of this job can be used as input for the Classification job, which analyzes how documents are categorized and generates a model. That model can then be used to predict categories of new documents when they are indexed.

    The Build Training Data job can be configured in Collections > Jobs in your Fusion UI instance.

    Enter the following information:

    • Spark Job ID used by the API to reference the job.

    • Location where your signals are stored, the Spark-compatible format for the signals, and filters for the query.

    • Location where your content catalog is stored and the Spark-compatible format of the catalog data.

    • Location and Spark-compatible format of the job output.

    • Field names for the query string, the category and item from the catalog, the signals item ID, and the signals count field.

    • Style of the text analyzer you want to use for the job.

    • Top category proportion in relation to all the categories, and the minimum number of the query category pair counts.

    For detailed configuration steps, see Classify New Queries. That process lets you predict the categories that are most likely to be returned successfully in a query.
