What is this? tagthe.net is a webservice intended to provide you with tags for your texts. You can use it in your applications, in other webservices or just play around with it. Why is it so different? In contrast to other services it uses the information that is present in the text, it analyses the content and tries to find out words that could be useful as tags. Currently it works with english, german and french texts.
