  ChatGPT has stimulated the research boom in the field of large language
models. In this paper, we assess the capabilities of ChatGPT from four
perspectives including Performance, Evaluation Criteria, Robustness and Error
Types. Specifically, we first evaluate ChatGPT's performance on 17 datasets
with 14 IE sub-tasks under the zero-shot, few-shot and chain-of-thought
scenarios, and find a huge performance gap between ChatGPT and SOTA results.
Next, we rethink this gap and propose a soft-matching strategy for evaluation
to more accurately reflect ChatGPT's performance. Then, we analyze the
robustness of ChatGPT on 14 IE sub-tasks, and find that: 1) ChatGPT rarely
outputs invalid responses; 2) Irrelevant context and long-tail target types
greatly affect ChatGPT's performance; 3) ChatGPT cannot understand well the
subject-object relationships in RE task. Finally, we analyze the errors of
ChatGPT, and find that "unannotated spans" is the most dominant error type.
This raises concerns about the quality of annotated data, and indicates the
possibility of annotating data with ChatGPT. The data and code are released at
Github site.
