Answering complex First-Order Logical (FOL) queries on large-scale incomplete
knowledge graphs (KGs) is an important yet challenging task. Recent advances
embed logical queries and KG entities in the same space and conduct query
answering via dense similarity search. However, most logical operators designed
in previous studies do not satisfy the axiomatic system of classical logic,
limiting their performance. Moreover, these logical operators are parameterized
and thus require many complex FOL queries as training data, which are often
arduous to collect …
