Innovation Clustering the news domain information in news events is of much greater granularity than any present day method can achieve. Annotating the unstructured blogosphere content at the granularity level of news events is a major step forward. Relations and sentiment analysis on clusters of text (instead of the usual named entities) has not been attempted before. An easy to navigate UI presenting the amount of information SYNC3 produces. Community creation and collaborative blog content creation.
