NATURAL LANGUAGE RESPONSE RECOMMENDATION CLUSTERING FOR RAPID RETRIEVAL

An interaction pace for a live natural language interaction is set. An acceptable response latency range is determined according to the interaction pace. By analyzing a live natural language query, a set of metadata tags corresponding to the query is determined. Using the set of metadata tags, a set of clusters of natural language query-response pairs is selected, a size of the set of clusters selected according to the acceptable response latency range. From the set of clusters, a query-response pairs is selected, wherein the query of the query-response pair has above a threshold relevance score with the first natural language query. From the selected query-response pair, a response recommendation is extracted, the response recommendation being a recommended response to the live natural language query, a latency between receipt of the live natural language query and extraction of the response recommendation being within the acceptable response latency range.
