Systems and methods for automatically detecting sentiments and assigning and analyzing quantitate values to the sentiments expressed in text
A method of analyzing sentiments includes receiving one or more strings of text, identifying sentiments related to a first topic from the one or more strings of text, and assigning a sentiment score to each of the sentiments related to the first topic, where the sentiment score corresponds to a degree of positivity or negativity of a sentiment of the sentiments. The method further includes calculating an average sentiment score for the first topic based on the sentiment score for each of the sentiments related to the first topic, determining a percentile for the first topic based on a frequency of sentiments related to the first topic, where the percentile for the first topic is determined with respect to a maximum frequency of sentiments related to one or more other topics, and computing an X-Score based on the average sentiment score and the percentile of the first topic.

7. The method of claim 6 , wherein the predefined range of sentiment scores is a range including: {−2, −1, 0, +1, +2}, wherein the sentiment score of −2 indicates a high degree of negativity of a sentiment and the sentiment score of +2 indicates a high degree of positivity of a sentiment.
8. The method of claim 1 , further comprising:
extracting sentiments from verbal sentiments captured in audio data or video data; and
converting the verbal sentiments to strings of text.
9. A system of analyzing sentiments comprising:
a computing device comprising:
a processor and
a non-transitory computer readable memory; and
a machine-readable instruction set stored in the non-transitory computer readable memory of the computing device that causes the system to perform at least the following when executed by the processor:
receive one or more strings of text;
identify a plurality of sentiments related to a first topic from the one or more strings of text;
assign a sentiment score to each of the plurality of sentiments related to the first topic, wherein each sentiment score corresponds to a degree of positivity or negativity of a sentiment of the plurality of sentiments;
calculate an average sentiment score for the first topic based on sentiment scores assigned to each of the plurality of sentiments related to the first topic;
determine a percentile for the first topic based on a frequency of sentiments related to the first topic, wherein the percentile for the first topic is determined with respect to a maximum frequency of sentiments related to one or more other topics; and
compute an X-Score for the first topic based on the average sentiment score and the percentile of the first topic.
10. The system of claim 9 , further comprising a display device communicatively coupled to the processor, wherein the machine-readable instruction set, when executed by the processor, further causes the system to:
generate for display a visual representation of the X-Score for the first topic and one or more X-Scores for the one or more other topics; and
display, on the display device, the visual representation.
11. The system of claim 10 , wherein the machine-readable instruction set, when executed by the processor, further causes the system to:
provide for selection of at least one of the first topic and the one or more other topics within the visual representation, wherein selection of at least one of the first topic or the one or more other topics causes the display device to present a second visual representation including a chart of one or more sentiment expressions related to a selected topic.
12. The system of claim 11 , wherein the visual representation includes at least one bar chart, wherein the X-Score for the first topic and one or more X-Scores for the one or more other topics are presented on the at least one bar chart.
13. The system of claim 11 , wherein the machine-readable instruction set, when executed by the processor, further causes the system to:
associate a color with the X-Score for the first topic and one or more X-Scores for the one or more other topics, wherein a different color corresponds to different X-Score values.
