Hosted By: Ben Lorica

This webcast will be discussing how Elasticsearch is taking search engine technology and branching it out from its roots in relevance-ranking search results to providing more insightful analysis of large datasets.

The biggest distinction between a database and a search engine is that the search engine starts with an assumption that not all information is equal. A search engine maintains the frequency of use of every word in its index and uses these counts to help relevance-rank matches, separating the signal from the noise.

Elasticsearch is taking this treasure-trove of statistics and developing powerful new analytic capabilities that can spot anomalies and patterns in subsets of information whether it represents text, IP addresses, bank account IDs, product purchases or more.

In this webcast we will demonstrate how various forms of useful signal can be separated from the backdrop of noise that exists in all of our datasets.

Applications include:

  • Making product recommendations
  • Root cause analysis in fault reports
  • Detecting unusual hotspots of crime
  • Training classifiers
  • Revealing badly categorised content
  • Detecting credit card fraud

These use cases are outlined in this blog post.
