Generating a plurality of selectable responses based on a database indexed by receiver devices storing responses to similar sms messages

A method for generating a plurality of most common responses to a Short Message Service (SMS) message, comprising the steps of:

• receiving, by one or more servers, the SMS message from a sender device, wherein the SMS message is addressed to a receiver device in a plurality of receiver devices and the SMS message comprises a string of characters;
• converting, by an encoder, the SMS message into a question vector, wherein the question vector comprises a vector having at least 200 dimensions;
• determining, by a similarity engine, a plurality of most similar question vectors from a plurality of receiver device question vectors stored in a database, wherein:
• the database stores a plurality of device groups indexed by a receiver device or a receiver, wherein each device group comprises a plurality of question vectors indexed by a different receiver device or a different receiver,
• the plurality of receiver device question vectors are stored in the database in a device group indexed by the receiver device or receiver,
• the plurality of receiver device question vectors are all derived from other SMS questions addressed to the receiver device,
• the plurality of receiver device question vectors do not include SMS questions not addressed to the receiver device, and
• the plurality of most similar question vectors are determined based on being mathematically closer to the question vector in high dimensional space as compared to other question vectors in the plurality of receiver device question vectors;
• determining a plurality of most common responses connected to the plurality of most similar question vectors;
• transmitting the SMS message and the plurality of most common responses to the receiver device, wherein the most common responses are displayed and selectable on the receiver device;
• receiving from the receiver device a selected response selected from the plurality of most common responses;
• storing the question vector and the selected response in the database, wherein the question vector and the selected response are associated with each other and placed in a device group indexed by the receiver device;
• and
• transmitting the selected most common response to the sender device.
