Structured Chemistry Reasoning with Large Language Models
CoRR(2023)
摘要
Large Language Models (LLMs) excel in diverse areas, yet struggle with
complex scientific reasoning, especially in the field of chemistry. Different
from the simple chemistry tasks (e.g., molecule classification) addressed in
previous studies, complex chemistry problems require not only vast knowledge
and precise calculation, but also compositional reasoning about rich dynamic
interactions of different concepts (e.g., temperature changes). Our study shows
that even advanced LLMs, like GPT-4, can fail easily in different ways.
Interestingly, the errors often stem not from a lack of domain knowledge within
the LLMs, but rather from the absence of an effective reasoning structure that
guides the LLMs to elicit the right knowledge, incorporate the knowledge in
step-by-step reasoning, and iteratively refine results for further improved
quality. On this basis, we introduce StructChem, a simple yet effective
prompting strategy that offers the desired guidance and substantially boosts
the LLMs' chemical reasoning capability. Testing across four chemistry areas –
quantum chemistry, mechanics, physical chemistry, and kinetics – StructChem
substantially enhances GPT-4's performance, with up to 30% peak improvement.
Our analysis also underscores the unique difficulties of precise grounded
reasoning in science with LLMs, highlighting a need for more research in this
area. Code is available at .
