Decay is a factor in the Score service results for content, user, and group quality that ensures new content scores place higher in search results than old contents do, reducing the old content's and author's quality score over time. If you have too strong decay values, older and more established content can have lowered scores, which in turn lowers its placement in search results, lowers the content quality score of the group and blog where it is located, and can lower the author quality score that the author has attained.
Decay is enabled or disabled on the site level Score Configuration page. However, the decay can be overridden for applications by its group owner. Note that this capability is added to the group manager/owner role, and cannot be granted to an individual as a single permission. This is useful when content maintains applicability and you don't want its quality score to be lowered just because it's been in the system for awhile.
- Navigate to Control Panel > System administration > Site administration > Site configuration > Score Configuration.
- Select the score you want to enable decay on from the tab list in the left column. For example, you might want to enable decay for the Content Quality score at the application level, but leave it at no for all other settings. Then only the content quality scoring would be affected, and aging content would not count against author or group author quality.
The following screen shot shows part of the Content Quality scoring default for the site, and shows that decay has been enabled for the score, so application-level decay overrides are allowed.
- Content quality
- Author quality
- Group author quality
- Abuse creator
- Abuse reporter
- To enable decay for this score, select Yes.
- For "Allow group manager overrides," select Yes.
- Navigate to Control Panel > Start managing groups > [group name] > Configure > Score configuration. The group application score configuration window appears.
Only scores that have decay enabled for them from the site-level setting are displayed in the score configuration list. In this example, we are using Content Quality.
- Click Override for the application. The score override value appears.
In the following screen shot, the Sample Forum half life decay value is displayed. Originally it displayed the default value, 30. However since we want this forum's content to age more slowly, we change the default to 60. (A higher value makes the content age more slowly; a lower value makes it age more quickly.)
