Web Intelligence and Visual Analytics to Reveal the Impact of Online Communication

Abstract

The visual analytics tools of the webLyzard Web intelligence platform show the lexical, geospatial and relational context of topics and entities referenced news and social media coverage. This talk illustrates the platform’s capabilities with examples from the Media Watch on Climate Change, the U.S. Climate Resilience Toolkit and the NOAA Media Watch. These applications aggregate environmental Web content from a wide range of online sources, visualize patterns identified in the gathered content, and have led to the development of the webLyzard Stakeholder Dialog and Opinion Model (WYSDOM). Going beyond bipolar assessments of sentiment, WYSDOM provides real-time insights into the success of marketing and public outreach activities. It enables scientists and communication professionals to better understand how different stakeholders perceive observable risks and policy options, how specific media channels react to new insights, and how journalists present scientific knowledge to the public.

Three ongoing research projects advance the presented methods for knowledge extraction [2] and visualization [3]: ASAP increases the scalability of these methods; PHEME enriches their functionality by adding veracity detection to reveal online myths and rumors; DecarboNet extends and applies them to build a knowledge co-creation platform [1] that combines content analysis and social network analysis to identify information diffusion patterns within and across online communities.
