I have a big database (500meg) that I want to put into OpenCyc. Is OpenCyc big enough to handle that?
Yes. But that’s not the best plan. You should have OpenCyc access the database and relay, not put the database directly into OpenCyc. If you’re entering knowledge into OpenCyc, don’t worry too much about memory usage; there are known approaches that may help with reducing this. But if you’re entering data, stop. Keep the data where it is. If you want to represent the contents of a billion-row database, then you will need to take the HL module dynamic access and caching approach. But if you’re just representing knowledge, not data, then put it in OpenCyc and don’t worry about memory.
