Dataset and code for "Event-Level Knowledge Editing". Event-level knowledge editing aims at editing newly occurred events into LLMs, thereby updating multiple factual knowledge and influenced tendencies at once. We construct a high-quality event-level editing benchmark $ELKEN$, consisting of 1,515 event edits, 6,449 questions about factual knowledge, and 10,150 questions about future tendencies.

1. Quick Start

The code repository is based on Pytorch and Transformers. Please use the following command to install the necessary dependcies. pip install -r requirements.txt.

2. Data Processor

Use run-processor.sh to process data for different models. Storage is in-place when experimenting with LLMs (GPT-3.5, GPT-4, Gemini Pro) that require API access, so we store one copy of identical data per model.

MODEL="gpt-3.5" # specify the model

cd data_processor

# process for IKE
python processor.py --model $MODEL

# process for ft
python processor_ft.py

# process for serac
python processor_serac.py --model $MODEL

# process for retrieval
python processor_retrieval.py --model $MODEL

Processing for Retrieval-based method and SERAC requires some pre-processing, and we provide our preprocessed files so you can just run bash run-processor.sh.

If you want to preprocess it yourself, please use the following scripts:

# For SERAC
cd serac
bash run.sh
bash infer.sh

# For Retrieval
cd retrieval
python bm25.py
python densy.py

3. Run Experiments

Using the codes in the folder ./llm to evaluate GPT-3.5, GPT-4, and Gemini Pro. You need to place your api key in corresponding files. Note that to run SERAC experiments you must use serac.py. Using the codes in the folder ./open-source to evaluate GPT-J, TULU 2, and Mistral 7B. You need to specify data_root_path and datasets in open-source/temp.py.

4. Evaluation

Using metric.py to get the reliability and locality for question-level and event-level metrics for factual knowledge and tendency separately.

Using overall_event_level_metric.py to get the overall event-level metrics, i.e., an event edit is reliable if and only if all the corresponding questions about factual knowledge and tendencies are correct.
