Knowledge Graphs represent real-world entities and the relationships between them. Multilingual Knowledge Graph Construction (mKGC) refers to the task of automatically constructing or predicting missing entities and links for knowledge graphs in a multilingual setting. In this work, we reformulate the mKGC task as a Question Answering (QA) task and introduce mRAKL: a Retrieval-Augmented Generation (RAG) based system to perform mKGC. We achieve this by using the head entity and linking relation in a question, and having our model predict the tail entity as an answer. Our experiments focus on evaluating the effectiveness of mRAKL compared to existing methods on knowledge graph completion and entity prediction tasks. The results demonstrate that mRAKL outperforms baselines on various low-resourced languages, showing its potential in improving multilingual knowledge graph construction tasks.
