Jobs Configuration Reference

These reference topics provide complete information about configuration properties for the Spark jobs that are enabled with a Fusion AI license.

For conceptual information and instructions for configuring and scheduling jobs, see Jobs and Schedules.

Additional jobs are available as part of the basic Fusion Server feature set.

  • ALS Recommender

    Use this job when you want to compute user recommendations or item similarities using a collaborative filtering recommender. You can also implement a user-to-item recommender in the advanced section of this job’s configuration UI. This job uses SparkML’s Alternating Least Squares (ALS).

    This job is deprecated as of Fusion 5.2.0. Use the BPR Recommender instead.
  • Cluster Labeling

    Use this job when you already have clusters or well-defined document categories, and you want to discover and attach keywords to see representative words within those existing clusters. (If you want to create new clusters, use the Document Clustering job.)

  • Co-occurrence Similarity

    Use this job when you only want to compute item-to-item similarities. This method is more lightweight than the generic Recommendations job.

  • Collection Analysis

    Use this job when you want to compute basic metrics about your collection, like average word length, phrase percentages, and outlier documents (with very many or very few documents).

  • Ground Truth

    Estimate ground truth queries using click signals and query signals, with document relevance per query determined using a click/skip formula.

  • Head/Tail Analysis

    Perform head/tail analysis of queries from collections of raw or aggregated signals, to identify underperforming queries and the reasons. This information is valuable for improving overall conversions, Solr configurations, auto-suggest, product catalogs, and SEO/SEM strategies, in order to improve conversion rates.

  • Item Similarity Recommender

    Use this job when you want to compute user recommendations based on pre-computed item similarities.

This job is only available in Fusion 4.0.
