2016 CSREA Press. All rights reserved. This paper describes a semantic toolkit for extracting information from multiple text and social media sources, and fusing the information so as to facilitate enhanced situational awareness and decision making. This innovative new capability assists information analysts to rapidly reason social media data to support enhanced situational awareness while significantly reducing the time and effort needed to convert data to action-enabling information. The semantic toolkit (DIGEST) provides the following capabilities: (1) rapid-sensing of multi-source text data to extract actionable knowledge including emerging themes, trends and patterns in sentiments, social-influence and information flow structures; (2) exploratory data analytics and knowledge discovery methods to support collaborative information analysis including social network analysis and event extraction and analysis; and (3) using the stored results from the exploratory information analyses to generate a variety of knowledge products.
