Automatic Grouping Bookmark Plugin/Extension

I need a plugin/extension that can auto grouping my browser's bookmarks. Basically, chrome or firefox browser already provide their users with default bookmark function. But, for those who that keep bookmarking until they has thousand of URLs link unsorted, it can become annoying. So, I want my bookmarks browser automatically sorted and was categorized into related folder based on some commonality. Example:- Football website should be saved into sport or news folder. The system supposedly executed according to some algorithm. I prefer to use pattern matching algorithm in this extension but if you have a better solution, feel free to tell me. The plugin should have a dictionary file that contain list of keyword. When users need to bookmark some links, the algorithm can do pattern matching. Supposed it can work on two condition:- 1. For the existing stored page. --> Match the keyword dictionaries with existing URLs, will adds the stored URLs into related folder. 2. For current view webpage. --> Match the keyword dictionaries with identified URLs, will adds the URLs into related folder. Explanation above is what I imagine in my plugin/extension. If you have better yet simple solution, I will take into consideration. Feel free to ask question if you don't [login to view URL] you.
