Cloud-based Machine learning

The ability to analyze information and use the results to make more informed decisions is something that interests a lot of people. Developers, publishers, and small to large business owners all collect an overwhelming amount of data pertaining to the work that they do. Employing a staff of analysts to sift through the onslaught of what can sometimes seem to be useless information is obviously one way to solve this problem, ‘Machine Learning’ is another.
BigML is providing developers a cloud platform for uploading data and having convinient way to process it with the help of RESTful API. Their pricing model is SaaS-based, which means users will have to pay only when they are analysing their data.

Google has already a similar service Google Prediction API that offers developper ability to build robust applications just like Amazon's product recommandation.

Textifter is another cloud-based service that allows you to analyze text to extract knowledge.
