Bug Description

Ubuntu 12.10, software-center 5.4.1.3

Steps to reproduce:
1. Clean installation of Ubuntu
2. Open the Software Center
3. Login using a Ubuntu single sign on
4. Enable software recommendations
5. Open Recommended for you

Some of the software is installed by default.

With customization:
(steps 1–5 above)
5. Install any of the one or several of the recommended software
6. Exit and restart the Software Center
7. Open Recommended for you

You get the same recommendations including the application you installed in your last session. (With enough applications

The recommendations in the Software Center are a bit off. This one thing in particular irks me because there is no value—assuming discovering new software is the value we are after—to the user to recommend them software they have already got installed on their system.

I suggest that software that is already installed on the current system should never be recommended. The software listings even have the little green check mark indicators showing the application is installed. (See attached screenshot.)

<https://wiki.ubuntu.com/SoftwareCenter/Recommendations#Generating_recommendations>: "The server should use a recommender algorithm to identify the ~50 packages *you don't have installed* that you're most likely to rate as excellent."

For example, within the Ubuntu Software Center I am recommended to install the Ubuntu Software Center. I cannot think of a scenario where this would be of any use to anyone.
