Rating Articles GroupLens GroupLens Variables
GroupLens makes a prediction for you about how much you will like a
news article. The predictions from GroupLens are on a scale from 1 to
5, where 1 is the worst and 5 is the best. You can use the predictions
from GroupLens in one of three ways controlled by the variable
gnus-grouplens-override-scoring
.
There are three ways to display predictions in grouplens. You may
choose to have the GroupLens scores contribute to, or override the
regular gnus scoring mechanism. override is the default; however, some
people prefer to see the Gnus scores plus the grouplens scores. To get
the separate scoring behavior you need to set
gnus-grouplens-override-scoring
to 'separate
. To have the
GroupLens predictions combined with the grouplens scores set it to
'override
and to combine the scores set
gnus-grouplens-override-scoring
to 'combine
. When you use
the combine option you will also want to set the values for
grouplens-prediction-offset
and
grouplens-score-scale-factor
.
In either case, GroupLens gives you a few choices for how you would like
to see your predictions displayed. The display of predictions is
controlled by the grouplens-prediction-display
variable.
