In this study, we introduce a new NLP pipeline for KG construction, which aim to efficiently extract the triples from unstructured scientific texts. The main feature of the method is that it can fine-tune the LLMs by annotating a small amount of data, and use the fine-tuned LLM to extract structured information from a large amount of unstructured text. The entire process does not rely on any prediction, which can maximize the authenticity and traceability of structured information. By employing this method, we construct a Functional Material Knowledge Graph (FMKG) contains the materials and their related knowledge from abstract of 150,000 peer-reviewed paper. After analyzing, we have demonstrated the effectiveness and credibility of FMKG.
In addition, our method and KG have great potential in different dimensions. Firstly, enhancing the depth of structured information extraction to encompass entire research papers promises a richer, more detailed knowledge graph. This involves not only expanding the scope of data analyzed but refining the process to capture nuances within complex scientific texts. Secondly, refining entity labels within our system allows for a more precise categorization of data, including incorporating detailed attributes such as synthesis conditions or property parameters, which significantly improves the granularity and utility of the knowledge graph. Thirdly, the versatility of our NLP pipeline suggests its applicability across different scientific domains, offering a template for constructing domain-specific knowledge graphs beyond material science. Lastly, integrating FMKG with existing knowledge graphs like MatKG opens avenues for creating a more interconnected and comprehensive dataset, facilitating advanced research and application development in material science and beyond.
