ELAN offers several ways to interact with web services. These web services are tools or applications that run on a web server, accept some resource(s) as input, apply an algorithm and return the result as output. Some of the Recognizers in the the section called “Audio And Video Recognizers” tab are available as a web service, in which case audio or video or any other type of sequential data are uploaded to be processed online. The web services available in this menu work with text rather than multimedia content. These tools can automate certain parts of the annotation process, such as tokenizing and part of speech tagging. These web services can be found by clicking Options > Web Services . The next section describes the web service WebLicht.
