Creating a structured prompt involves defining the instruction format, which, in our case, aligns with the task of generating structured JSON or abstractive summaries for materials science texts. Following the instructions provided in the documentation, we initiate the structured prompt by defining columns that represent the input and output structure. For the task of JSON extraction, this would entail a clear definition of the input text and the desired output in a structured JSON format. Similarly, for the abstractive summarization task, the columns would reflect the input text and the expected abstractive summary.
