Meta Learning for Few-Shot Knowledge Graph Completion
This report summarizes the key insights from "Meta learning based few shot knowledge graph completion with domain selected aggregation." We highlight its innovative approach to addressing data sparsity in Knowledge Graph Completion (KGC) by introducing a domain-selected neighborhood aggregator and a relation meta-learner. This method effectively filters irrelevant noise and captures deep semantic correlations, leading to superior performance in few-shot learning scenarios.

Knowledge graph completion aims to fill in missing facts within a knowledge graph. This paper focuses on few-shot knowledge graph completion (FKGC), a particularly challenging scenario where very limited training data is available for certain relations. Traditional methods struggle under these conditions due to data sparsity and the inability to generalize well to unseen relations.
The MLGD method addresses these limitations by learning to adapt quickly to new, unseen relations with only a few examples. This capability is crucial for enterprise applications dealing with evolving data, niche domains, or rapidly changing information, where manually curating large datasets for every new relation is impractical.

Core Innovation Spotlight
0.533 Hits@10 in Few-Shot KG Completion (5-shot NELL-One)This metric highlights the superior performance of MLGD due to its novel domain-selected aggregation and meta-learning approach, significantly reducing noise and enhancing semantic understanding in sparse data environments.
Ablation Study: Module Impact on MRR (5-shot NELL-One)
| MLGD Variant | MRR Score | Performance Change (vs. Full MLGD) |
|---|---|---|
| Full MLGD | 0.355 | Baseline |
| w/o Neighborhood Aggregator (NA) | 0.323 | 3.2% lower |
| w/o Gating Mechanism (GATE) | 0.341 | 1.4% lower |
| w/o Top-k Selection | 0.329 | 2.6% lower |
| w/o Relation Meta-Learner (RL) | 0.302 | 5.3% lower |
The ablation study demonstrates the critical contribution of each proposed module to MLGD's overall performance. Removing any key component, especially the Relation Meta-Learner or Neighborhood Aggregator elements, leads to a noticeable decline in Mean Reciprocal Rank (MRR), validating their effectiveness in handling few-shot KGC challenges.
Case Study: Improved Relation Learning Examples
The MLGD method consistently outperforms baselines even in complex relational scenarios, demonstrating its robust understanding of diverse semantic contexts. Below are examples comparing MLGD's MRR against GANA, a strong baseline:
-
Relation: Produced By
MLGD MRR: 0.722 vs GANA MRR: 0.589MLGD significantly improves performance for relations like "Produced By," indicating its enhanced ability to infer creation links even with limited data.
-
Relation: Athlete injured his body part
MLGD MRR: 0.267 vs GANA MRR: 0.164In this specialized relation, MLGD's context-aware aggregation allows for better understanding of specific entities and their associated facts, leading to a much higher MRR.
-
Relation: Geopolitical location of person
MLGD MRR: 0.213 vs GANA MRR: 0.190Even for broad and potentially noisy relations, MLGD maintains a performance edge, showcasing its effective noise suppression and precise semantic modeling.
