Earl Wagner will present "Rich Interfaces for Reading News on the Web"
Earl will present this talk at IUI2009on February 9th.
Abstract: Using content-specific models to guide information retrieval and extraction can provide richer interfaces to end-users for both understanding the context of news events and navigating related news articles. We discuss a system, Brussell, that uses semantic models to organize retrieval and extraction results, generating both storylines explaining how news event situations unfold and also biographical sketches of the situation participants. We generalize these models to introduce a new category of knowledge representation, an explanatory structure, that can scale up to include information from hundreds of documents, yet still provide model-based UI support to end-users. An informal survey of business news suggests the broad prevalence of news event situations indicating Brussell’s potential utility, while an evaluation quantifies its performance in finding kidnapping situations.
