articles grouped by their age. On the right-hand side the users are provided with meta-
information like a visualization of the cluster's development or the key concepts and
named entities the news cluster is dealing with.
An extra analysis page offers the search for quotations and sentiment tags. Users
have the possibility to specify whether to search for quotations or sentiment tags
and to select how to order the results. At this point our interface allows sorting by
relevance and actuality. The resulting quotations or sentiment tags, respectively, are
presented at the top of the page and the corresponding news articles thereunder.

view that directly compares opinionated quotations according to a topic or a target
entity. The comparison view allows users to easily grasp, e.g., the most opposing or
the most frequent/important comments. We aim to create a service with full archive
