Visualizing Contextual Information in Aggregated Web Content Repositories

Understanding stakeholder perceptions and the impact of campaigns are key insights for communication experts and policy makers. A structured analysis of Web content can help answer these questions, particularly if this analysis involves the ability to extract, disambiguate and visualize contextual information. After summarizing methods used for acquiring and annotating Web content repositories, we present visualization techniques to explore the lexical, geospatial and relational context of entities in these repositories. The examples stem from the Media Watch on Climate Change, a publicly available Web portal that aggregates environmental resources from various online sources.
