US Patent 11080471 Rules-based automated chart description system

A system includes a request processing module configured to receive a chart description request associated with an asset. The system also includes a rules store configured to store rules, a rules application module configured to determine a set of rules and a set of results by applying each rule in the set of rules to chart data associated with the asset, a rules selector module configured to select a subset of results from the set of results, a text generation module configured to generate a text description based on the subset of results, and an output module configured to transmit the text description. Each of the rules includes a relevancy score. The selection of the subset of results is based on the score of each rule associated with the set of results. The description describes a chart associated with the asset.
