MetaHGNIE: Meta-Path Induced Hypergraph Contrastive Learning in Heterogeneous Knowledge Graphs
MetaHGNIE addresses node importance estimation in heterogeneous knowledge graphs by modeling higher-order dependencies and integrating structural and semantic information. It constructs a higher-order knowledge graph using meta-path sequences and employs a dual-channel architecture: a hypergraph attention network for structural features and a sparse-chunked hypergraph transformer for semantic representations. A cross-modal fusion with contrastive learning ensures robust alignment. Extensive experiments demonstrate its superior performance over state-of-the-art baselines.

Methodology
Performance
Efficiency
MetaHGNIE introduces a novel framework for node importance estimation in heterogeneous knowledge graphs. It explicitly models higher-order dependencies among multiple entities by constructing a meta-path-induced hypergraph, where typed hyperedges capture multi-entity relational contexts. The framework employs a dual-channel encoding architecture to disentangle structural and semantic information. A structure-aware hypergraph attention network aggregates local higher-order topological features, while a semantic hypergraph transformer encodes global contextual semantics with sparse chunking for efficiency. Finally, structural and semantic embeddings are fused via contrastive alignment and auxiliary supervision for robust cross-modal representations.

Node Importance Estimation
The proposed dual-channel design of MetaHGNIE significantly enhances performance. Compared to existing dual-channel graph and hypergraph models, MetaHGNIE achieves superior scores on both Spearman correlation and NDCG@100. This indicates that MetaHGNIE's hybrid architecture, combining Hypergraph Attention and Sparse-Chunked Hypergraph Transformer, effectively captures complex structural and semantic relations, leading to more accurate node importance estimation.

MetaHGNIE's Sparse-Chunked Attention (SCA) mechanism addresses the quadratic complexity of traditional hypergraph transformers, which are prohibitive for large-scale KGs. SCA reduces computational and memory overhead by focusing only on non-zero entries and processing data in chunks, preventing memory overflow and making the model scalable for real-world enterprise applications.
Scalability & GPU Efficiency through Sparse-Chunked Attention
Scenario: A large-scale enterprise with a complex heterogeneous knowledge graph involving millions of nodes and hyperedges faces prohibitive computational costs and memory overflows with conventional transformer-style attention, which requires dense incidence matrix computations.
Solution: MetaHGNIE incorporates a Sparse-Chunked Attention (SCA) mechanism. This module operates directly on the sparse COO form of the incidence matrix, computing attention only on non-zero entries and normalizing via scatter-softmax. By processing the hypergraph in chunks, SCA avoids allocating large tensors and global COO arrays, thereby preventing memory overflow and reducing computational overhead.
Results:
- Runtime reduction of over 30% across all datasets, with an 84.7% decrease on FB15K (from 1.561s to 0.239s).
- GPU memory usage reduced by 49.06% on FB15K and 56.12% on TMDB5K, enabling previously infeasible configurations.
- Maintains expressiveness while substantially improving efficiency by eliminating redundant computations.
Impact: The SCA mechanism in MetaHGNIE makes large-scale hypergraph modeling tractable for enterprises, offering significant cost savings and enabling the application of sophisticated AI to previously unmanageable datasets without sacrificing model performance or expressiveness.
