A debate is defined as a formal discussion on a set of related topics in a public meeting, in which opposing perspectives and arguments are put forward. In this paper, we develop automated perspective discovery techniques which would contribute to the understanding of features (i.e. social, political, cultural, religious beliefs, goals, and practices) shared by each side of the debate. Secondly, we show that, compared to a semi-automated process, our perspective discovery algorithms not only identify larger number of relevant features, but they also yield a higher accuracy scaling of moderate to extreme organizations on both sides of a debate.

We proved the viability of our impact forecasting approach using a SVM based forecaster on six months of NYT corpus-consisting of 16,852 articles. We experimented with different feature selection and ranking algorithms including standard frequency based methods, as well as a new method named ImpactRank. Our ImpactRank based forecaster performed as the best feature ranking technique while providing a graph suitable for browsing and identifying the most influential topics, entities and interrelationships going into its impact predictions.

We develop a ranking system that utilizes ranked perspectives to map 26 UK Islamic organizations on a set of socio-cultural, political and behavioral scales based on their web corpus. We create a gold standard ranking of these organizations through an expertise elicitation tool. We compute expert-to-expert agreements, and we present experimental results comparing the performance of the QUIC based scaling system to another baseline method. The QUIC based algorithm not only outperforms the baseline method, but it is also the only system that consistently performs at area expert-level accuracies for all scales.

If an analyst in her area has to follow and map all these according to the timeline they happen, the task quickly becomes overwhelming. We present an online tool which attempts to ease the analyst’s task of finding all news articles about an event, and sorting and mapping them on a timeline. We implemented an incremental clustering algorithm working on real-time incoming news, experimenting with different feature sets, including named entities and sentence overlap methods. We evaluated these approaches using Document Understand Conference (DUC) datasets
