I need to implement one blog application on share market. I've already implemented auto blog system which retrives blogs from different bloggers as rss. I need to tag them all according to comapany name. For Example: At first, i'll enter all the comapny name (around 30,000-40,000) as tag. If post has company name specified in tag list then categorized it with same tag. Later i shold be able to retrive it by tag name.
