Coreference resolution[edit] In computational linguistics, coreference resolution is a well-studied problem in discourse.

Introduction ConceptNet¹ is a commonsense knowledgebase, composed mainly from the Open Mind Project, written and put together by Hugo Liu and Push Singh (Media Laboratory Massachusetts Institute of Technology).
ConceptNet 2.1 (current version at the time of this composition) also includes MontyLingua, a natural-language-processing package. ConceptNet is written in Python but it's commonsense knowledgebase is stored in text files. To read more specific details about the complete overview of ConceptNet, read Liu and Singh's outstanding paper (pdf). Most of the projects available from MIT are not written in Microsoft Visual Studio .NET and I am attempting to make use of ConceptNet for educational, research purposes, and just to have fun with the technology involved.
The Visual Studio .NET C# ConceptNetUtils (CNU) Version 2.x Class Library ConceptNetUtils (CNU) version 2 uses IronPython and edited ConceptNet script files to achieve the same results as the Python version of ConceptNet.
