Measuring Social Activity
When you have a lot of user interaction on your web site, it can be helpful to try to separate the signal from the noise. Liferay contains a lot of applications which end users can use to communicate with each other and provide information. Some of this information is good and helpful and some of it can be rather unhelpful. Using Liferay’s Social Activity feature will help show which users are making real, valuable contributions.
Figure 9.9: The Social Activity page of the Control Panel allows you to enable social activity for assets and specify points for participation and contributions.
To activate Social Activity, you’ll first need to determine which collaboration applications you want to use Social Activity. There are currently three types of content you can use with Social Activity - Blogs Entries, Message Board Messages, and Wiki Pages. Activation is a la carte - so you can use it on one, two, or all three applications. Social Activity tracks three metrics from within each of these applications two are for the user - Participation and Contribution - and the other, Popularity, is for the asset involved.
Let’s activate Social Activity for Blogs Entries. Check the box next to Blog Entry. You now have options to set point values and limits on several different actions for blogs. You’ll notice each item on the list has dropdowns you can use to set the number of participation and contribution points; popularity points are tied directly to contribution points. In addition to that, you can expand the box by clicking Limits in the top right of each list item. You can use this to set a limit on how many times a user can perform this activity with a specific asset and receive the requisite points. For some activities, you can set limits on both participation and contribution points, but on new content creation, you can only set limits on participation points.
It might not be immediately obvious, but for all actions that do not involve the creation of a new asset, all of the contribution points go to the original asset creator and all popularity points go to the original asset. That means if Votes on a Blog is set to have 1 Participation point and 5 Contribution points (and therefore 5 Popularity points), the user who votes on the asset will receive 1 participation point, the user who created the asset will receive 5 contribution points, and the asset will receive 5 popularity points.
Figure 9.10: You can set limits for your site’s social activity.
It’s easy to assign points–you can arbitrarily assign points for just about anything–the challenge is making the points significant in some way. As mentioned before, the primary purpose of social activity tracking is to make sure that users who regularly contribute to the portal and participate in discussions are recognized as such. So the central piece of the social equity display is the User Statistics portlet.
The User Statistics portlet displays a list of users ranked by an amalgamation of their participation and contribution scores. By clicking on the Configuration icon for the portlet, you can change some of the specifics of the rankings. There are five check boxes that you can enable or disable:
Rank by Contribution: If this is checked, a user’s contribution score will be used as a factor in calculating their rank.
Rank by Participation: If this is checked, a user’s participation score will be used as a factor in calculating their rank.
Show Header Text: Determines whether the title shows or only the rankings.
Show Totals: Toggles the display of the users activity score next to their name.
Display Additional Activity Counters: You can toggle the display of any number of other pieces of information next to the users name in the statistics, ranging from the number of comments on assets a user has created to the number of wiki articles that the user has created. If you want to display multiple data points, you can click the plus button to add one and the minus button to remove one. You can have as many data points displayed as you want, but displaying too many might make your portlet a little unwieldy.

The Group Statistics portlet provides some more advanced data analytics. If you add it to a page, and click on the configuration icon, you can select the assets to track. You can click the plus button to add additional slots, and choose from the various metrics available for each slot, covering virtually any action that a user can perform on content in the portal. If you decide that you’re displaying too many metrics, you can click the minus button for a particular slot on the configuration view to remove it.
There are a wide-ranging number of actions that you can provide social credit for. Users can receive credit for everything from subscribing to a blog to writing wiki articles. You can easily tweak the numbers in the Control Panel if it becomes clear that certain activities are weighted too high or too low.
Social Activity can be an invaluable tool for portals that are heavily driven by community-created content. It allows you to easily recognize users who are major contributors and it indicates to new users whose advice will be most trustworthy. Social Activity is easy to set up and can be configured differently for each site, increasing the flexibility of your portal.
Beyond Liferay’s social API, there is also support for the OpenSocial standard.
