BlogTrackers: Analyzing Social Media for Cultural Modeling

Description

This research project is a preliminary joint effort to integrate domain knowledge of a special cultural interest with novel search capabilities for assessing political risks. In particular, this project attempts to address three critical questions in order to stay in the frontier of stability operations in a global, forward-looking view: 1. the importance of the blogosphere to military or stability operations; 2. the significance of the blog research to these operations; and 3. the identification and development of tools of blog tracking and analysis to understand the communities of interest and help advance global security and prosperity. We first provide background information on blogs - Web-based media with increasing popularity among youths all over the world, and on Indonesia – a strategically significant country that serves as a case study for the proposal. Secondly, we illustrate the pressing need for studying the blogosphere as a new dimension for identifying pre-conflict indicators and potential threats. Thirdly, we articulate the demand for novel search capabilities that can integrate domain knowledge in search and scale up with the inordinate number of disconnected blogs of special interests in the digital jungle. Finally, we propose to design, develop, deploy, and evaluate BlogTrackers, a proof-of-concept system that distills and manifests the proposed research tasks and derived results.

TweetTracker

Our latest system TweetTracker focuses on tweets collected from Twitter to support event monitoring and analysis. More information about this project can be found here.
