Text analysis system, and characteristic evaluation system for message exchange using the same

A method for analyzing text, the method comprising:

• converting characters of the text into a numerical time series signal, wherein the numerical time series signal comprises a time series conversion of the characters in numerical format;
• generating a waveform comprising extracted information from the numerical time series signal, wherein the extracted information comprises features based on politeness in language, a quantifiable use of conjunctions, use of idioms, or a combination thereof;
• determining whether the text is written by a specific user based on an analysis of the waveform against a threshold;
• and
• detecting anomalous text different from the extracted information based on the determination result,
• wherein the method is for a message exchange system,
• wherein the text is part of a message communicated using the message exchange system,
• wherein the message exchange system is for halting transmission of the message in response to an anomaly being detected based on an analysis of the waveform against the threshold, and
• wherein the method further comprises generating a notification message to a user of the message exchange system in response to halting the transmission.

A device for analyzing text, the device comprising:

• a non-transitory memory storage comprising instructions;
• and
• a processor in communication with the non-transitory memory storage, the instructions, when executed by the processor, cause the processor to:
• convert characters of the text into a numerical time series signal, wherein the numerical time series signal comprises a time series conversion of the characters in numerical format,
• generate a waveform comprising extracted information from the numerical time series signal, wherein the extracted information comprises features based on politeness in language, a quantifiable use of punctuations, a quantifiable use of conjunctions, and use of idioms, and
• determine whether the text is written by a specific user based on an analysis of the waveform against a threshold;
• and
• detect anomalous text different from the extracted information based on the determination result,
• wherein the device is part of a message exchange system,
• wherein the text is part of a message communicated using the message exchange system,
• wherein the message exchange system is for halting transmission of the message in response to an anomaly being detected based on an analysis of the waveform against the threshold, and
• wherein the instructions, when executed by the processor, cause the processor to generate a notification message to a user of the message exchange system in response to halting the transmission.
