Data transfer between isolated clusters is imperative for cybersecurity education, research, and testing. Such techniques facilitate hands-on cybersecurity learning in isolated clusters, allow cybersecurity students to practice with various hacking tools, and develop professional cybersecurity technical skills. Educators often use these remote…

The exponential growth of scholarly publications in recent years has presented a daunting challenge for researchers to keep track of relevant articles within their research field. To address this issue, we examined the capabilities of InfraNodus, an AI-Powered text network analysis platform. InfraNodus promises to provide insights into any…

Automatic coding of short text responses opens new doors in assessment. We implemented and integrated baseline methods of natural language processing and statistical modelling by means of software components that are available under open licenses. The accuracy of automatic text coding is demonstrated by using data collected in the "Programme…

The "p"-median clustering model represents a combinatorial approach to partition data sets into disjoint, nonhierarchical groups. Object classes are constructed around "exemplars", that is, manifest objects in the data set, with the remaining instances assigned to their closest cluster centers. Effective, state-of-the-art implementations of…

Proposes and illustrates a method of identifying key words in text, and leads from this proposal to the notion of key key words (words that are key in many texts). Notes that a key key word has associates: words that are key in the same texts as a given key key word. Notes that these associates can be grouped together in clumps. (18 references)…

This report describes cluster analysis methodology and illustrates its potential merits for educational research by describing a study designed to identify the natural subgroups existing among students beginning a secondary level remedial mathematics course. Cluster analysis forms groups of relatively homogeneous subjects represented in large data…
