Guiding Graph Embeddings using Path-Ranking Methods for Error Detection innoisy Knowledge Graphs
This work addresses noise in automatically constructed knowledge graphs, which is an incremental improvement for data quality in domains like biomedicine.
The paper tackles error detection in noisy knowledge graphs by proposing a hybrid and modular methodology, comparing it on benchmarks and a biomedical dataset to showcase its potential.
Nowadays Knowledge Graphs constitute a mainstream approach for the representation of relational information on big heterogeneous data, however, they may contain a big amount of imputed noise when constructed automatically. To address this problem, different error detection methodologies have been proposed, mainly focusing on path ranking and representation learning. This work presents various mainstream approaches and proposes a hybrid and modular methodology for the task. We compare different methods on two benchmarks and one real-world biomedical publications dataset, showcasing the potential of our approach and providing insights on graph embeddings when dealing with noisy Knowledge Graphs.
