Joomla 1.7 site hacked. What to do?

Recently my Joomla 1.7 site was hacked. I knew nothing about this. The site worked fine. But when i did some test search with Google and found that the site is found with keywords that are not used in my site. When i looked at Google cache i was impressed that there are different pages. Contents of my pages was replaced with advertising links and texts.

This was some sort of cloaking. And this meant my Joomla site is infected with something bad.

I already sow similar problem for my another Joomla 1.5 site year ago. So this time i know what to do.

Using sentiment analysis to predict FOREX quotes

I worked on some tools for News4Trader.com . That service has algorithm for sentiment analysis of business news. For each message there is list of Tags and sentiment (positive or negative) for each tag . Sentiment is calculated using Sentiment Analysis methods.

Using gathered data we tried to use Tags' sentiments for prediction of Forex quotes

Business news sentiment analysis. First results

Sentiment analysis of financial news

What doest it mean to get sentiment of the text? There are a lot of scientific researches on this subject. Most of them are focused on getting sentiment of text that is "some review of something". For example, movie reviews.

Some technologies allows to categorize texts for private "emotional" texts and just facts. And sentiments are recognized only for private texts that contains someone's thoughts, that really can be sentimental.

I am interested in sentimental analysis of business news.
