Hi Nil, Fascinating indeed!
What is the status of the pattern miner and the interestingness measure? I'm not asking because I'm in a rush (I still have about two weeks before I'm ready), before I can use it for my dissertation paper, I still have work to do with respect to the AtomSpace representation of the ontologies and also with auto-scaling of my system's memory so that I can load in the Gazetteer, which is huge. I think that in about two weeks, I'd like to give that interesting pattern mininer a spin on the AtomSpace filled with two ontologies along with a huge, global gazetteer, if I can. Gdelt might also be an interesting source of knowledge to learn new things about Sustainable Development from (https://www.gdeltproject.org/). In the meantime, I'm working on encoding as much about those relationships as there is information for in the ontology: if a relationship is transitive, symmetric, etc. I want to at least encode that in addition to the Evaluation PredicateNode construct, which I understand, but I think that coding more of the correct structure will help to gain better insight. In the medium term, I'd be interested in seeing if the full social-cultural-institutional meaning of particular types of relations (what do they predict, etc.) could emerge from intense online interactions between people and the AtomSpace. That is what I'm working towards academically, while trying to make use of it for business so that I can finance the operation.
