Hi,
How to do pure logical inferencing in DeepDive on normal relations. Documentations and examples only show probabilistic inferencing with first-order-logic operators to co-relate variable relations. In a Knowledge Base creation logical inferencing is important to derive new knowledge from the facts on the basis of logical rules. Having a DataLog like syntax gave us a premonition that we can write prolog-like rules to encode logical relations like transitivity & reflexivity. Normal derivation syntax did not help realise the same as it's not processing the rules recursively or right away rejecting in the case when relations appear both in the head and body. Trying to use logical operators like implication & conjunction with normal relations also gave error.
Is there some way to realise these aspects with DeepDive's syntax or the only ways are either try to do probabilistic inferencing or write an UDF ?
