Hi. I made a plugin called Automatic Post Tagger. As the name suggests, its purpose is assigning tags to posts. It can save a lot of time and it is perfect for autoblogs. All you have to do is create a list of tags and their related words. The plugin will handle the rest.
You can find it in the official WP Plugin Directory.
Enjoy!
