Natural Intelligence was my AI/NLP project during my M.S. years. It's basically a question answering system based on Combinatory Categorial Grammar (CCG) as the theory of grammar and Conceptual Graphs (CG) for knowledge representation and reasoning. Open Cyc is used for upper ontology and commonsense handling. Here is the Springer link to the latest publication about the project.
Currently, I am working on a new version of this project on my startup: PragmaCraft. It is called Intelligent Search Assistant, and helps you to semantically filter search results by natural language.
