Text Classification with Elasticsearch


Course Summary

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 course will teach you how to build a classification system using the same features that make Elasticsearch so powerful for search. 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
