    ontocomp

    OntoComP is a Protégé 4 plug-in for completing OWL ontologies

    OntoComP is a Protégé 4 plug-in for completing OWL ontologies. It enables the user to check whether an OWL ontology contains "all relevant information" about the application domain, and extends the ontology appropriately if this is not the case. It achieves this by asking the user questions of the form "are instances of classes C1 and C2 also instances of class C3?". If the user confirms such a question, then a new axiom of the application domain that does not follow from the ontology has...

    A capsule tree is a general purpose, self-balancing tree data structure for large, ordered, data-sets. It is designed to provide the same characteristics as B-trees and B+trees, but built from the ground up for in-memory usage. In other words, there are no provisions for “slow” I/O cases. The original motivation for this tree was a better backend for memory managers. However, the end result was a new sub-category of trees. The implementation giving here is just one implementation of...

    Sorting Algorithms

    An educational demo of how sorting algorithms work.

    This is a small Java swing application that shows different sorting algorithms working on the same set of data. The user can modify the speed of execution and the type of data to sort and execute it step by step. The tooltip of each algorithm's box shows the source code that is executed and a little explanation got from wikipedia. This application is aided to computer science students who want to better understand how the algorithms work.
