Project Objectives (1/2)

Identify correlated text excerpts among news articles to provide with the thematology by grouping news events in news themes and main news categories Main output:

• Sets of news article excerpts (corresponding to news events) and the centroids from

which they were derived

• News thematology

News article processing News article processing Update the centroids and use them to find blog excerpts that comment on the corresponding news events, while performing sentiment analysis on them Main output:

• Blog posts that comment to news events and the associated excerpts

• Graph connecting news events, blog excerpts and their attributes

and relations User Interface User Interface Use existing tagging and annotation information to extract attributes and temporal and causal relations between news events Main output:

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

• f 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.
