I just came across this search service, Silobreaker, that is quite interesting, it places into context search results. Silobreaker is an online search service for news and current events that delivers meaning and relevance beyond traditional search and aggregation engines. Its relational analysis and explanatory graphics provide users with unparalleled contextual insight into the news stories of the day.
Take a look at what I found on my book “Virtual Shadows” for example.
