# Relation Extraction for Inverse Relations
This dataset is designed to evaluate the robustness of Relation Extraction (RE) models, with a specific focus on **Inverse Relations** and entity substitution. It is derived from the **FewRel** and **TekGen** benchmarks (from Text2Bench).
## Dataset Summary
The primary goal of this dataset is to test whether models can recognize a relationship regardless of the direction or the surface form of the entities. It includes:
1. **Inverse Mapping**: Every sample includes both the forward relation (e.g., *Mother*) and its logical inverse (e.g., *Child*).
2. **Artificial Substitutions**: A version of the dataset where real-world entities are replaced with synthetic names (e.g., replacing "Denmark" with "Emilyfort") to test if models rely on memorized entity knowledge rather than linguistic context.
### Relation Examples
| Forward Relation | Inverse Relation |
| :--- | :--- |
| **Child** (P40) | **Mother** (P25) |
| **Child** (P40) | **Father** (P22) |
| **Follows** (P155) | **Followed by** (P156) |
| **Has Part** (P527) | **Part of** (P361) |
## Dataset Structure
The dataset is provided in JSON format and split into four main distributions:
* **Original FewRel/TekGen**: The ground-truth sentences and relations.
* **Artificial FewRel/TekGen**: Sentences where entities have been substituted with synthetic placeholders.
* **Relation Metadata**: Supplemental files providing human-readable definitions for Wikidata P-IDs and TekGen relation strings.
### Key Fields
* `tokens`: The input text (tokenized or raw string) in FewRel.
* `sent`: The input sentence (raw string) in Tekgen
* `head` / `tail`: The subject and object entities.
* `head_to_tail`: The ID/Name of the forward relation.
* `tail_to_head`: The ID/Name of the inverse relation.
* `artificial_data`: A mapping showing which `Original` entities were changed to which `Artifical` placeholders.
## Usage
You can load this dataset for tasks such as:
* **Text Classification**: Predicting the relation ID between two entities.
* **Text Generation**: Generating a sentence that expresses a specific inverse relation.
