Extracting Polymer Nanocomposite Samples from Full-Length Documents
CoRR(2024)
摘要
This paper investigates the use of large language models (LLMs) for
extracting sample lists of polymer nanocomposites (PNCs) from full-length
materials science research papers. The challenge lies in the complex nature of
PNC samples, which have numerous attributes scattered throughout the text. The
complexity of annotating detailed information on PNCs limits the availability
of data, making conventional document-level relation extraction techniques
impractical due to the challenge in creating comprehensive named entity span
annotations. To address this, we introduce a new benchmark and an evaluation
technique for this task and explore different prompting strategies in a
zero-shot manner. We also incorporate self-consistency to improve the
performance. Our findings show that even advanced LLMs struggle to extract all
of the samples from an article. Finally, we analyze the errors encountered in
this process, categorizing them into three main challenges, and discuss
potential strategies for future research to overcome them.
