This paper presents a system that allows users to specify a perspective when searching news results. The system visualizes search results from major search engines to show how much they inherently discuss the specified perspective when returning articles for a given query. An interface that shows perspectives could be useful for journalists, media researchers, or general users exploring news topics.

Abstract
The result set from a search engine for any user's
query may have an inherent perspective given
issues with the search engine or issues with the
underlying collection. This demonstration paper
presents a system that allows users to specify at
query time a perspective together with their query.
The system then presents results from well-known
search engines with a visualization of the results
which allows the users to quickly surmise the
presence of the perspective in the returned set.
“The potential bias
may be introduced due
to issues with the
search engine itself or
with the underlying
collection”
How much Google, Yahoo, and Bing return articles that inherently discuss
“activism” when the query “edward snowden” is issued by the user
