Class RetrieveAndRank

java.lang.Object

com.ibm.watson.developer_cloud.service.WatsonService

com.ibm.watson.developer_cloud.retrieve_and_rank.v1.RetrieveAndRank

All Implemented Interfaces:

ClusterLifecycleManager, SolrConfigManager

public class RetrieveAndRank
extends WatsonService
implements ClusterLifecycleManager, SolrConfigManager

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 to find “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.
