RANKING CONTENT USING USER FEEDBACK
A technology is described for ranking content using user feedback. A method can include presenting a content entry to a plurality of users to enable viewing of the content entry. Positive and negative ratings can be captured about the content entry from the plurality of users. A relative deviation value can be calculated using the positive ratings and negative ratings for the content entry to form a raw rating score using a processor. Another operation can be scaling the raw rating score via a power function to form a controversial rating score using a processor. The content entry may then be displayed in a ranked order with other content entries based on the controversial rating score.
1 . A method for ranking content using user feedback, comprising:
presenting a content entry to a plurality of users to enable viewing of the content entry;
capturing positive and negative ratings about the content entry from the plurality of users;
computing a relative deviation value using the positive ratings and negative ratings for the content entry using a processor;
scaling the relative deviation value via a power function to form a controversial rating score using a processor; and
displaying the content entry in a ranked order with other content entries based on the controversial rating score.
2 . The method as in claim 1 , further comprising selecting a minimum value from positive rating counts and negative rating counts as an operand for the power function.
3 . The method as in claim 1 , further comprising scaling the rating score using a logarithmic weight function.
4 . The method as in claim 1 , further comprising scaling the rating score using a power weighting function.
5 . The method as in claim 4 , further comprising applying the power weighting function where a power applied is a fractional power.
6 . The method as in claim 4 , further comprising applying the power weighting function where a power applied is greater than zero and less than ½
7 . The method as in claim 1 , further comprising computing a relative deviation value for the positive ratings and the negative ratings using:
PN
P
+
N
where P is a number of positive ratings for the content entry and N is a number of negative ratings for the content entry.
8 . A system for ranking content using user feedback, the system comprising:
a presentation module to present content entries to a plurality of users for viewing;
a rating module to capture positive and negative ratings for the content entries from the plurality of users;
a statistical module to compute a relative deviation value using the positive ratings and negative ratings for content entries to form raw rating scores;
a scaling module to apply a power function to the raw rating scores to form controversial rating scores; and
a display module to display the content entries in a ranked order based on the controversial rating scores.
9 . The system as in claim 8 , wherein the scaling module selects a minimum value from between the positive rating counts and the negative rating counts as an operand for the power function.
10 . The system as in claim 8 , wherein the scaling module scales the raw rating score using a power function that is a logarithmic weight function.
11 . The system as in claim 8 , wherein the scaling module scales the raw rating score using a power weighting function.
12 . The system as in claim 8 , wherein the scaling module applies the power function using a fractional power.
13 . The system as in claim 8 , further comprising applying the power function using a power greater than zero and less than ½.
14 . The method as in claim 8 , wherein the statistical module computes a relative deviation value for the positive ratings and the negative ratings using:
PN
P
+
N
where P is a number of positive ratings for the content entry and N is a number of negative ratings for the content entry.
15 . The system of claim 8 , wherein a web server is used to execute the rating module and to capture positive and negative ratings about the content entries.
16 . A method for ranking content using user feedback, comprising:
presenting content entries to a plurality of users to enable viewing of the content entries;
capturing positive and negative ratings about the content entries from the plurality of users;
computing an inverted relative deviation value for the positive ratings and negative ratings to form a raw rating score;
applying a sign value obtained by comparing the positive ratings and negative ratings to the raw rating score to form a rating score; and
displaying the content entries in a ranked order based on the rating score.
17 . The method as in claim 16 , further comprising computing the rating score that is a highest rated or a lowest rated score.
18 . The method as in claim 17 , wherein applying a sign value further comprises obtaining a sign value to determine how high a content entry is rated by subtracting a negative rating count from a positive rating count and applying the resulting sign to the raw rating score.
19 . The method as in claim 17 , wherein applying a sign value further comprises obtaining a sign value to determine how low a content entry is rated by subtracting a positive rating count from a negative rating count and applying a resulting sign to the raw rating score.
20 . The method as in claim 16 , further comprising computing an inverted relative deviation value for the positive ratings and the negative ratings using:
P
+
N
PN
where P is a number of positive ratings for the content entry and N is a number of negative ratings for the content entry.
