Questions tagged [retrieve-and-rank]

Use the Retrieve and Rank tag when the question is about the IBM Watson Retrieve and rank service.

The IBM Watson Retrieve and Rank service helps users find the most relevant information for their query by using a combination of search and machine learning algorithms to detect "signals" in the data. Built on top of Apache Solr, developers load their data into the service, train a machine learning model based on known relevant results, then leverage this model to provide improved results to their end users based on their question or query.
