Document scoring features in SharePoint 2010

If you use SharePoint to build a document management solution, scoring a document is actually a fairly common requirement. Unfortunately, in the previous release, SharePoint did not have this feature built in, and of course, there are community projects that add this functionality to the SharePoint document library by customizing the development approach. SharePoint 2010 finally gives the document library (in fact, all lists) the ability to score documents (and list items).

In the document library settings, open the Level Settings page, and then enable rating on the page.

The document library then adds two site columns, rank (0-5), and number of levels. The former is used to store the average of all users scoring the document, which is used to store how many users have exaggerated the document.

In this way, in the view of the document library, you can see the following interface. By sliding the mouse over the "level (0-5)" field, the user can give the specified document a score.

After the user scores the document, the value is not immediately aggregated (and the average is calculated). SharePoint 2010 is timed to summarize the rating values by using a timer job in the background called "User Profile Service application-social scoring joint", which is run hourly by default. If you want it to run more frequently, you can find the timer job in the "Monitor-timer job-review job definition" in SharePoint 2010 Central Administration, modify its schedule, or simply click on the "Run Now" button to make it execute immediately.

After the score is calculated, the user can see the summary results shown in the following figure.
