ATOKE

This is the repository for our paper [AAAI 2024] History Matters: Temporal Knowledge Editing in Large Language Model.

Datasets

Overview

ATOKE dataset contains three temporal knowledge editing datasets.

The datasets are included in datasets/. There are three files:

• AToKe-SE.json: Single Edit dataset.
• AToKe-ME.json: Multiple Edits dataset.
• AToKe-EE.json: Extending Edit dataset.

Data format

The dataset is saved as a list of dicts, each of which represents a data instance. We take AToKe-ME, the most complex format, as an example, while AToKe-SE and AToKe-EE are both simplifications of AToKe-ME. An example in AToKe-ME is shown below.

• requested_rewrite: The list of editing facts we want to inject into the model: only one element in AToKe-SE and AToKe-EE; multiple consecutive-time fact lists in AToKe-ME. (In general, we follow the format of the MQuAKE dataset. In particular, we place the question of the current time here.)
  • time_true and time_new: The current time interval of the model and the new time interval we want to inject into the model. "gptj: true" indicates the current time interval before editing the model.
  • evaluation: includes both completion (cloze-style for GPT-j) and natural language QA formats, and includes both direct questions about the current time and questions that include current time intervals. paraphrase_completion is used to eliminate the effects of different textual expressions
• history_evaluation: includes both completion and natural language QA formats, and includes both direct questions about past time and questions that include past time intervals
• answer and answer_alias: the gold answer before injecting new facts into language models. answer_alias is a list of aliases of the answer.
• new_answer and new_answer_alias: the gold answer after injecting new facts into language models.

For AToKe-EE only:

• The object before and after editing is unchanged and the time interval is extended.
• There is no history_evaluation, because the facts don't change, just the time interval of the facts.

Evaluation

We evaluate the model's ability to edit temporal knowledge in terms of two dimensions: the time at which the model is questioned (historical, current) and the form of the time at which it is questioned (relative, explicit).

	Historical	Current
Relative	Historical Relative time Question Score (HRS)	Current Relative time Question Score (CRS)
Explicit	Historical Explicit time Question Score (HES)	Current Explicit time Question Score (CES)

In addition, we eliminate the effect of question description by paraphrasing the question. We measure this as the Paraphrase Question Score.

Examples are as follows:

• time:
  • historical: "Billy Wrigglesworth used to play for"
  • current: "Billy Wrigglesworth's team is"
• time form:
  • relative: "Billy Wrigglesworth's team is"
  • explicit: "From 1947 to 1948, Billy Wrigglesworth is a player of"
  • paraphrase: "From 1947 to 1948, Billy Wrigglesworth plays for"
