System and method for evaluating sentiment
An example system and method elicits reviews and opinions from users via an online system or a web crawl. Opinions on topics are processed in real time to determine orientation. Each topic is analyzed sentence by sentence to find a central tendency of user orientation toward a given topic. Automatic topic orientation is used to provide a common comparable rating value between reviewers and potentially other systems on similar topics. Facets of the topics are extracted via a submission/acquisition process to determine the key variables of interest for users.
1. A user interface for providing orientation information about a topic, the user interface comprising:
color-based indicators arranged on a display, a color of each of the color-based indicators reflecting a measure of a respective orientation derived from a corresponding block of text about the topic, wherein different colors reflect different measures of orientation; and
a selecting device for selecting one of the color-based indicators to cause display of at least a portion of the corresponding block of text.
2. The user interface according to claim 1 , wherein the color-based indicators are linearly arranged.
3. The user interface according to claim 1 , wherein the color-based indicators are arranged in a row-and-column matrix.
4. A computing device comprising a user interface according to claim 1 .
5. A personal digital assistant comprising a user interface according to claim 1 .
6. A mobile telephone comprising a user interface according to claim 1 .
7. A system comprising:
a computer processor;
storage accessible to the computer processor for storing orientation values for each of multiple blocks of text about a topic; and
an interface for providing orientation information about the topic, the interface including:
a color strip having colors each reflecting a respective orientation for a corresponding block of text about the topic; and
a movable visual indicator for selecting one of the colors to cause display of at least a portion of the corresponding block of text.
8. The system according to claim 7 , wherein the interface is web-based.
9. The system according to claim 7 , wherein the interface is configured for display on a mobile telephone.
10. The system according to claim 7 , wherein the color strip includes at least a first array of discrete segments.
11. The system according to claim 10 , wherein the first array of segments comprises a linear array of segments.
12. The system according to claim 10 , wherein the first array of segments comprises a row-and-column array of segments.
13. The system according to claim 7 , wherein the interface further comprises:
a second color strip displayed concurrently with the color strip, each color of the second strip reflecting a respective orientation for a corresponding block of text on a second topic different than the topic,
wherein the visual indicator is further movable for selecting one of the colors of the second color strip to cause display of at least a portion of the corresponding block of text.
14. A system comprising:
a computer processor;
storage accessible to the computer processor for storing orientation values for each of multiple blocks of text about a topic; and
an interface for providing orientation information about the topic, the interface including a color indicator whose color reflects an aggregate orientation for multiple blocks of text about the topic.
15. The system according to claim 14 , wherein the aggregate orientation corresponds to an average orientation for the multiple blocks of text about the topic.
16. A non-transitory computer-readable storage medium comprising instructions for execution on at least one computer processor to enable the computer processor to perform operations comprising:
providing a display of a color strip having colors each reflecting a respective orientation for a corresponding block of text about the topic; and
in response to using a visual indicator to select one of the colors, causing display of at least a portion of the corresponding block of text.
17. The non-transitory computer-readable storage medium according to claim 16 , wherein the color strip comprises an array of indicators.
18. The non-transitory computer-readable storage medium according to claim 17 , wherein the array of indicators comprises a linear array of indicators.
19. The non-transitory computer-readable storage medium according to claim 17 , wherein the array of indicators comprises a row-and-column array of indicators.
