Using Decision Trees for Coreference Resolution
This paper describes RESOLVE, a system that uses decision trees to learn how
to classify coreferent phrases in the domain of business joint ventures. An
experiment is presented in which the performance of RESOLVE is compared to the
performance of a manually engineered set of rules for the same task. The
results show that decision trees achieve higher performance than the rules in
two of three evaluation metrics developed for the coreference task. In addition
to achieving better performance than the rules, RESOLVE provides a framework
that facilitates the exploration of the types of knowledge that are useful for
solving the coreference problem.Comment: 6 pages; LaTeX source; 1 uuencoded compressed EPS file (separate);

In Vivo Evaluation of the Secure Opportunistic Schemes Middleware using a Delay Tolerant Social Network
Over the past decade, online social networks (OSNs) such as Twitter and
Facebook have thrived and experienced rapid growth to over 1 billion users. A
major evolution would be to leverage the characteristics of OSNs to evaluate
the effectiveness of the many routing schemes developed by the research
community in real-world scenarios. In this paper, we showcase the Secure
Opportunistic Schemes (SOS) middleware which allows different routing schemes
to be easily implemented relieving the burden of security and connection
establishment. The feasibility of creating a delay tolerant social network is
demonstrated by using SOS to power AlleyOop Social, a secure delay tolerant
networking research platform that serves as a real-life mobile social
networking application for iOS devices. SOS and AlleyOop Social allow users to
interact, publish messages, and discover others that share common interests in
an intermittent network using Bluetooth, peer-to-peer WiFi, and infrastructure
WiFi.Comment: 6 pages, 4 figures, accepted in ICDCS 2017. arXiv admin note: text
