Using System Dynamics to Analyze the Effect of Funding Fluctuation on Software Development
(Massachusetts Institute of Technology. Engineering Systems Division, 2014-10)
Almost everyone understands that budget fluctuations have an impact on software development, but it is difficult to estimate the magnitude of the impact and all the causes. This paper uses System Dynamics modeling to examine ...
Institutional Foundations for Cyber Security: Current Responses and New Challenges
(Massachusetts Institute of Technology. Engineering Systems Division, 2014-11)
Almost everyone recognizes the salience of cyberspace as a fact of daily life. Given its ubiquity, scale, and scope, cyberspace has become a fundamental feature of the world we live in and has created a new reality for ...
Evaluating and Aggregating Data Believability across Quality Sub-Dimensions and Data Lineage
(Massachusetts Institute of Technology. Engineering Systems Division, 2008-01)
Data quality is crucial for operational efficiency and sound decision making. This paper focuses on believability, a major aspect of data quality. The issue of believability is particularly relevant in the context of Web ...
Towards better understanding Cybersecurity: Or are "Cyberspace" and "Cyber Space" the same?
(Massachusetts Institute of Technology. Engineering Systems Division, 2014-10)
Although there are many technology challenges and approaches to attaining cybersecurity, human actions (or inactions) also often pose large risks. There are many reasons, but one problem is whether we all “see the world” ...
Comparative Analysis of Cybersecurity Metrics to Develop New Hypotheses
(Massachusetts Institute of Technology. Engineering Systems Division, 2012-01)
Few Internet security organizations provide comprehensive, detailed, and reliable quantitative metrics, especially in the international perspective across multiple countries, multiple years, and multiple categories. As ...
A Cubic Framework for the Chief Data Officer: Succeeding in a World of Big Data
(Massachusetts Institute of Technology. Engineering Systems Division, 2014-11)
A new breed of executive, the chief data officer (CDO), is emerging as a key leader in the organization. We provide a three-dimensional cubic framework that describes the role of the CDO. The three dimensions are: (1) ...
SPARQL Query Mediation for Data Integration
(Massachusetts Institute of Technology. Engineering Systems Division, 2012-01)
The Semantic Web provides a set of promising technologies to make sophisticated data integration much easier, because data on the semantic Web is allowed to be connected by links and complex queries can be executed against ...
