Rules-based automated chart description system

A method comprising:

• receiving a chart description request, wherein the chart description request is associated with an asset;
• and
• in response to receiving the chart description request:
• retrieving chart data from a chart associated with the chart description request;
• determining a set of rules from a plurality of rules stored in a storage circuit, wherein each rule of the plurality of rules is associated with a respective relevancy score;
• determining a set of results by applying each rule in the set of rules to the chart data associated with the asset, such that the set of results corresponds to the set of rules;
• removing ones of the set of results that do not satisfy a criterion, wherein the criterion is associated with a true outcome;
• identifying a first subset of rules from the set of rules that respectively correspond to remaining ones of the set of results;
• selecting a second subset of rules from the first subset of rules, wherein the second subset of rules comprise rules having the highest associated relevancy scores;
• identifying results from the set of results which correspond to the second subset of rules;
• setting the identified results as a subset of results;
• obtaining narrative text based on the subset of results;
• generating a text description of the chart including the subset of results and corresponding narrative text, wherein the text description describes a chart associated with the chart description request;
• and
• transmitting the text description to a source of the chart description request.

A method comprising:

• receiving a chart description request, wherein the chart description request is associated with an asset;
• in response to the chart description request including an image of a chart, determining an identifier by performing optical character recognition on the image and obtaining chart data based on the identifier;
• determining whether historical data associated with the identifier is available;
• in response to determining that the historical data associated with the identifier is available, retrieving the historical data associated with the identifier;
• in response to determining that the historical data associated with the identifier is not available, extracting the historical data associated with the identifier from the image;
• and
• in response to receiving the chart description request:
• determining a set of rules from a plurality of rules stored in a storage circuit, wherein each rule of the plurality of rules is associated with a respective relevancy score;
• determining a set of results by applying each rule in the set of rules to the chart data and the historical data associated with the identifier;
• selecting a subset of results from the set of results, wherein the selection of the subset of results is based on the relevancy scores of the rules associated with the set of results;
• generating a text description based on the subset of results, wherein the text description describes a chart associated with the chart description request;
• and
• transmitting the text description to a source of the chart description request.
