No classes have been scheduled, but you can always Request a Quote.


Text analysis, tokenization, and stop word removal is as much a function of search as it is of classification, making Elasticsearch the perfect tool for text classification. This instructor-led course will teach you how to build a classification system using the same features that make Elasticsearch so powerful for search.
Note: This course is a module of the Data Science specialization.


After exploring precision, recall, F1 scoring, fallback mechanisms and more, you will learn how to use tools like percolation and significant terms aggregation to build better text classification systems in your own use case.

Topics Covered

  • Designing Classification Systems with the Elastic Stack
  • Query Optimization with Significant Terms Aggregations
  • Using Percolators for Classification
  • Fallback Planning
