“…Geometric relational embeddings encode real-world relational knowledge by geometric objects such as convex regions like n-balls (Kulmanov et al, 2019), convex cones (Zhang et al, 2021;, axis-parallel boxes (Vilnis et al, 2018;Xiong et al, 2022c;Ren et al, 2020) and non-Euclidean manifold components (Xiong et al, 2022a). A key advantage of these geometric embeddings is that they nicely model the set-theoretic semantics that can be used to capture logical rules of KGs (Abboud et al, 2020), ontological axioms (Kulmanov et al, 2019;Xiong et al, 2022c), transitive closure (Vilnis et al, 2018), and logical query for multi-hop reasoning (Ren et al, 2020). Different from all previous work, ShrinkE is the first geometric embedding that aims at modeling inference patterns for hyper-relational KGs.…”
