Pundit Annotator Pro
http://thepund.it/annotator-pro-web-annotation/

Pundit Annotator Pro is the perfect tool for researchers, journalists and professionals who want to exploit the power of semantic technology while annotating the web by building semantic relations with other web pages, text fragments or Wikipedia. Annotation consists in attaching data to a document or to a fragment of it, by providing additional information (metadata) about an existing resource. Semantic Annotation allows you to bridge the ambiguity of the natural language when expressing notions and their computational representation in a formal language. By telling a computer how data items are related and how relations can be evaluated automatically, it becomes possible to process complex operations such as filtering and searching. Pundit Annotator Pro is an advanced tool for semantic web annotation: it allows you to highlight and comment on any text and to create semantic annotations (with one or more triples) on any web page. It is designed for professional users who want to exploit the power of web annotation and the semantic web: a) scholars, who want to perform advanced critical editions; b) journalists, and in particular structured journalists; and c) any user interested in exploiting the potential of semantic web and linked data.
