Attribute Based Encryption for Secure Access to Cloud Based EHR Systems
(IEEE, 2018-09-10)
Medical organizations find it challenging to adopt cloud-based electronic medical records services, due to the risk of data breaches and the resulting compromise of patient data. Existing authorization models follow a ...
CADET: Computer Assisted Discovery Extraction and Translation
(2017-11-27)
Computer Assisted Discovery Extraction and Translation (CADET) is a workbench for helping knowledge workers find, label, and translate documents of interest. It combines a multitude of analytics together with a flexible ...
Advanced Large Scale Cross Domain Temporal Topic Modeling Algorithms to Infer the Influence of Recent Research on IPCC Assessment Reports
(American Geophysical Union, 2016-12-12)
One way of understanding the evolution of science within a particular scientific discipline is by studying the temporal influences that research publications had on that discipline. We provide a methodology for conducting ...
Event Nugget Detection using Thresholding and Classification Techniques
(National Institute of Standards and Technology, 2016-11-14)
This paper describes the Event Nugget Detection system that we submitted to the TAC KBP 2016 Event Track. We sent out two runs; UMBC1 and UMBC2. UMBC1 is a sentence-level classification system based on Convolution Neural ...
Participation in TAC KBP 2017: Cold Start TEDL and Low-resource EDL
The JHU HLTCOE participated in the Cold Start and the edl tasks of the 2017 Text Analysis Conference Knowledge Base Population evaluation. For our sixth year of participation in Cold Start we continued our research with ...
Ontology-Grounded Topic Modeling for Climate Science Research
(AKA Verlag, Berlin, 2018-10-08)
In scientific disciplines where research findings have a strong impact on society, reducing the amount of time it takes to understand, synthesize and exploit the research is invaluable. Topic modeling is an effective ...
Capturing policies for fine-grained access control on mobile devices
(IEEE, 2016-11-01)
As of 2016, there are more mobile devices than humans on earth. Today, mobile devices are a critical part of our lives and often hold sensitive corporate and personal data. As a result, they are a lucrative target for ...
Deep Understanding of a Document's Structure
(ACM, 2017-12-05)
Current language understanding approaches focus on small documents, such as newswire articles, blog posts, product reviews and discussion forum discussions. Understanding and extracting information from large documents ...
Discovering Scientific Influence using Cross-Domain Dynamic Topic Modeling
(IEEE, 2017-01-15)
We describe an approach using dynamic topic modeling to model influence and predict future trends in a scientific discipline. Our study focuses on climate change and uses assessment reports of the Intergovernmental Panel ...
