Question classification is an important part in modern Question Answering systems. Most approaches to question classification are based on handcrafted rules. Recent studies classify simple questions using machine learning techniques and recommends SVM as on of the best performing classifiers. This study applies a hierarchical classifier based on the SVM(More)
Disruption Tolerant Networks (DTNs) can be characterized by intermittent network connectivity and unguaranteed end-to-end paths. Replication based routing is often used to improve the message delivery but it suffers from high traffic overhead and uncontrolled forwarding paths. In this paper, we propose a Multi-Policy Link State Routing (MPLSR) protocol to(More)
Collaborative querying harnesses the collective search experiences of users for query formulation. We present the Query Graph Visualizer (QGV), a visual collaborative querying system that recommends related queries to a userpsilas submitted query through a network visualization scheme. Users are able to explore the query network and select queries for(More)
