N2 - Knowledge graphs (KGs) have emerged as a pivotal infrastructure in computational and data-driven materials engineering, enabling structured representation, reasoning, and integration of heterogeneous data for accelerated discovery. By organizing materials data into interconnected entities and relationships, KGs facilitate advanced querying, inference, and machine learning applications across domains such as materials informatics, high-throughput computation, and inverse design. This review synthesizes recent advancements in KG construction from multimodal datasets, including text corpora, biomolecular integrations, and crystalline structures. We examine how graph neural networks and representation learning enhance molecular contrastive learning and pre-training frameworks for improved molecular representations. In the landscape of computational materials ecosystems, KGs support semantic integration and terminology standardization, bridging simulation and experiment through active learning systems and uncertainty quantification. Applications in autonomous laboratories highlight closed-loop discovery, where KGs enable dynamic knowledge propagation and event-sourced provenance management. We provide an original synthesis framing KGs as unifying backbones for data-model-experiment cycles, emphasizing systems-level integration over isolated tools. Challenges in scalability and interoperability are noted, with future directions toward hybrid human-AI workflows. This narrative underscores KGs' role in transforming materials discovery from empirical to predictive paradigms, fostering interdisciplinary convergence in materials science.
