The evaluation of recommender system is often biased towards accuracy, which is hard to balance all participants' interests. In this paper, a novel recommendation strategy using expanded neighbor collaborative filtering (ECF) is presented. Different from the standard collaborative filtering (CF), this recommendation strategy takes into account the second-order neighbors, which are expected to contribute...
Quantifying the impact of scientific papers objectively is crucial for research output assessment, which subsequently affects institution and country rankings, research funding allocations, academic recruitment, and national/international scientific priorities. While most of the assessment schemes based on publication citations may potentially be manipulated through negative citations, in this paper,...
We introduce Polinode, an online tool for performing network analysis. Polinode is aimed at commercial and non-commercial users alike and supports both research-related use cases as well as teaching network analysis to students. One of its primary advantages is that it is web-based. It therefore doesn't require any software downloads and opens up new avenues for collaboration and the incorporation...
Effective software engineering demands a coordinated effort. Unfortunately, a comprehensive view on developer coordination is rarely available to support software-engineering decisions, despite the significant implications on software quality, software architecture, and developer productivity. We present a fine-grained, verifiable, and fully automated approach to capture a view on developer coordination,...
Conflict resolution models play key roles in coordinating simultaneous interactions in multi-user collaborative virtual environments (VEs). Currently, conflict resolution models are first-come-first-serve (FCFS) and dynamic priority (DP). Known to be unfair, the FCFS model grants all interaction opportunities to the agilest user. Instead, the DP model permits all users the perception of equality in...
In this research, we develop a hybrid recommendation system recommendation system for healthy living programs to patients with chronic diseases. Our experiments indicate that our model compared favorably against other real-world recommendation applications in terms of accuracy. We also demonstrated that the proposed hybrid algorithm performed better than traditional CF in terms of error rate, precision...
Exchanging structured business documents is inevitable for successful collaboration in electronic commerce. A prerequisite, for fostering the interoperability between business partners utilizing different business document standards, is a mapping between different standards. However, the effort involved in creating those mappings is hard to estimate. For example, the complexity of standardized formats...
Trusted Layered Sensing has evolved from an Air Force Research Laboratory (AFRL) initiative to a vision now shared across government research agencies, industry, and academia. “Trust” is viewed as the most critical issue affecting Layered Sensing architectures since it's impossible to build Situational Awareness (SA) out of inaccurate, misleading, or denied information. Sensing systems (SS) consist...
