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 ...
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 ...

(National Institute of Standards and Technology, 2016-11-14)
The JHU HLTCOE participated in the Cold Start and the Entity Discovery and Linking tasks of the 2016 Text Analysis Conference Knowledge Base Population evaluation. For our fifth year of participation in Cold Start we ...
UMBC at SemEval-2018 Task 8: Understanding Text about Malware
(2018-06-05)
We describe the systems developed by the UMBC team for 2018 SemEval Task 8, SecureNLP (Semantic Extraction from CybersecUrity REports using Natural Language Processing). We participated in three of the sub-tasks: (1) ...
Interactive Knowledge Base Population
(2015-05-15)
Most work on building knowledge bases has focused on collecting entities and facts from as large a collection of documents as possible. We argue for and describe a new paradigm where the focus is on a high-recall extraction ...
Extracting cybersecurity related linked data from text
(IEEE Computer Society Press, 2013-09-16)
The Web is typically our first source of information about new software vulnerabilities, exploits and cyber-attacks. Information is found in semi-structured vulnerability databases as well as in text from security bulletins, ...
KELVIN: a tool for automated knowledge base construction
(2013-06-03)
We present KELVIN, an automated system for processing a large text corpus and distilling a knowledge base about persons, organizations, and locations. We have tested the KELVIN system on several corpora, including: (a) the ...
A Collaborative Approach to Situational Awareness for CyberSecurity
(IEEE, 2012-10-14)
Traditional intrusion detection and prevention systems have well known limitations that decrease their utility against many kinds of attacks. Creating a new system that collaboratively combines information from traditional ...
Evaluating the Quality of a Knowledge Base Populated from Text
(ACM, 2012-06-07)
The steady progress of information extraction systems has been helped by sound methodologies for evaluating their performance in controlled experiments. Annual events like MUC, ACE and TAC have developed evaluation approaches ...
HLTCOE Approaches to Knowledge Base Population at TAC 2009
(National Institute of Standards and Technology, 2009-11-01)
The HLTCOE participated in the entity linking and slot filling tasks at TAC 2009. A machine learning-based approach to entity linking, operating over a wide range of feature types, yielded good performance on the entity ...
