We have meticulously collected and cleaned existing Information Extraction (IE) datasets, integrating a total of 26 English IE datasets and 7 Chinese IE datasets. As shown in Figure 1, these datasets cover multiple domains including **general**, **medical**, **financial**, and others. |
|
|
|
In this study, we adopted the proposed "`schema-based batched instruction generation method`" to successfully create a large-scale, high-quality IE fine-tuning dataset named **IEPile**, containing approximately `0.32B` tokens. |
|
|
|
Based on **IEPile**, we fine-tuned the `Baichuan2-13B-Chat` and `LLaMA2-13B-Chat` models using the `Lora` technique. Experiments have demonstrated that the fine-tuned `Baichuan2-IEPile` and `LLaMA2-IEPile` models perform remarkably on fully supervised training sets and have achieved significant improvements in **zero-shot information extraction tasks**. |

## 2.Data |
|
|
|
|
|
### 2.1Construction of IEPile |
|
|
|
We concentrate on instruction-based IE, thus the construction of schema within the instructions is crucial. This is because they reflect the specific extraction requirements and are dynamically variable. Previous approaches with existing IE datasets often employ a rather extensive schema processing strategy when constructing instructions, utilizing all schemas within a label set for instruction building, raising two potential issues: |
|
1. **Inconsistency in the number of schema queries within instruction between training and evaluation**. For example, the model's performance will decrease if it is trained on about 20 schema queries but tested with either 10 or 30, even if the training and evaluation schemas are similar in content. |
|
2. **Inadequate differentiation among schemas in the instructions**. For example, semantically similar schemas like "layoffs", "depart" and "dismissals", may present co-occurrence ambiguities that could confuse the LLMs. Such schemas should co-occur more frequently within the instruction. |
|
|
|
Therefore, we introduce the following solutions: 1οΌHard Negative Schema; and 2οΌ Batched Instruction Generation. |
|
|
|
|
|
 |
|
|
|
|
|
<details> |
|
<summary><b>Hard Negative Schema</b></summary> |
|
|
|
Assuming that dataset $\mathcal{D}$ possesses a full label set $L$. For a given text $S$, the schemas present in its annotation constitute the positive schema set $Pos\_L$, while others form the negative schema set $Neg\_L$. In our analysis, we discover that the primary cause of model misjudgment stems from the semantic ambiguity of the schema. In traditional approaches, the $Neg\_L$ is simply defined as $L - Pos\_L$. However, they overlook a critical aspect: it is important to pay special attention to negative schemas that are semantically close to positive schemas. Inspired by the theory of contrastive learning, we construct a hard negative schema dictionary $\mathcal{K}$, where each key represents a unique schema and the associated value is a collection of schemas that are semantically similar to the key schema. Based on this, we define the hard negative schema set as $Hard\_L = \mathcal{K}[Pos\_L]$, and the other negative schema set as $Other\_L = L - Pos\_L - Hard\_L$. The final $Neg\_L$ is constituted by $Hard\_L$ and a small subset of $Other\_L$. Through this strategy, we not only present semantically similar schemas more frequently within the instruction but also reduce the number of training instances without sacrificing model performance. |

|
<summary><b>Batched Instruction Generation</b></summary> |
|
|
|
Subsequently, we obtain the final schema set $L' = Pos\_L + Neg\_L$. We employ a batched instruction generation method, limiting the number of schemas inquired in each instruction to the number of $split\_num$, which ranges between 4 to 6. Therefore, $L'$ will be divided into $|L'|/split\_num$ batches for querying, with each batch querying $split\_num$ schemas. Consequently, even if the number of schemas inquired during the evaluation phase differs from that of training, the batched mechanism allows us to distribute the inquiries across $split\_num$ schemas, thereby mitigating the decline in generalization performance. |

### 2.2Data Format of IEPile |
|
|
|
Each instance in `IEPile` contains four fields: `task`, `source`, `instruction`, and `output`. Below are the explanations for each field: |
|
|
|
|
|
| Field | Description | |
|
| :---: | :---: | |
|
| task | The task to which the instance belongs, one of the five types (`NER`, `RE`, `EE`, `EET`, `EEA`). | |
|
| source | The dataset to which the instance belongs. | |
|
| instruction | The instruction for inputting into the model, processed into a JSON string via json.dumps, including three fields: `"instruction"`, `"schema"`, and `"input"`. | |
|
| output | The output in the format of a dictionary's JSON string, where the key is the schema, and the value is the extracted content. | |
|
|
|
|
|
In `IEPile`, the **instruction** format of `IEPile` adopts a JSON-like string structure, which is essentially a dictionary-type string composed of the following three main components: |
|
(1) **`'instruction'`**: Task description, which outlines the task to be performed by the instruction (one of `NER`, `RE`, `EE`, `EET`, `EEA`). |
|
(2) **`'schema'`**: A list of schemas to be extracted (`entity types`, `relation types`, `event types`). |
|
(3) **`'input'`**: The text from which information is to be extracted. |
|
|
|
The file [instruction.py](./ie2instruction/convert/utils/instruction.py) provides instructions for various tasks. |
|
|
|
Below is a **data example**: |
|
|
|
```json |
|
{ |
|
"task": "NER", |
|
"source": "CoNLL2003", |
|
"instruction": "{\"instruction\": \"You are an expert in named entity recognition. Please extract entities that match the schema definition from the input. Return an empty list if the entity type does not exist. Please respond in the format of a JSON string.\", \"schema\": [\"person\", \"organization\", \"else\", \"location\"], \"input\": \"284 Robert Allenby ( Australia ) 69 71 71 73 , Miguel Angel Martin ( Spain ) 75 70 71 68 ( Allenby won at first play-off hole )\"}", |
|
"output": "{\"person\": [\"Robert Allenby\", \"Allenby\", \"Miguel Angel Martin\"], \"organization\": [], \"else\": [], \"location\": [\"Australia\", \"Spain\"]}" |
|
} |
|
``` |
|
|
|
The data instance belongs to the `NER` task, is part of the `CoNLL2003` dataset, the schema list to be extracted includes ["`person`", "`organization`", "`else`", "`location`"], and the text to be extracted from is "*284 Robert Allenby ( Australia ) 69 71 71 73 , Miguel Angel Martin ( Spain ) 75 70 71 68 ( Allenby won at first play-off hole )*". The output is `{"person": ["Robert Allenby", "Allenby", "Miguel Angel Martin"], "organization": [], "else": [], "location": ["Australia", "Spain"]}`. |
|
|
|
> Note that the order of schemas in the output is consistent with the order in the instruction. |

|
|
|
## 5.Limitations |
|
|
|
From the data perspective, our study primarily focuses on schema-based IE, which limits our ability to generalize to human instructions that do not follow our specific format requirements. |
|
Additionally, we do not explore the field of Open Information Extraction (Open IE); however, if we remove schema constraints, our dataset would be suitable for Open IE scenarios. |
|
Besides, IEPile is confined to data in English and Chinese, and in the future, we hope to include data in more languages. |
|
|
|
From the model perspective, due to computational resource limitations, our research only assessed two models: Baichuan and LLaMA, along with some baseline models. Our dataset can be applied to any other large language models (LLMs), such as Qwen, ChatGLM, Gemma. |
