It incorporates three interactive modules: (1) The tagger enables flexible and individual textual markup and markup editing. (2) The analyzer incorporates a query language and predefined functions. It also includes a query builder that allows users to construct queries from combinations of pre-defined questions while allowing for manual modification for more specific questions.
