# TempKB

## Overview

TempKB is a comprehensive collection of knowledge graph data designed to train ML models on knowledge graph completion and reasoning tasks.

## Dataset Structure

The dataset is organized into the following main components:

Train Set: 7764337 instances for training models.

Validation Set: 117510 instances for validating model performance.

Test Set: 117327 instances for final evaluation.

## Data Fields

Each instance in the dataset contains the following fields:

- `head`: the head entity
- `relation`: the relationships between the head and tail entities
- `tail`: the tail entity
- `start`: start time of the event
- `end`: end time of the event
- `type`: temporal information type, which is one of the following:
  - `NONE`: no start or end time
  - `TIMESTAMP`: start time only
  - `INTERVAL`: start and end time

## Example Instance

```json
{
  "head": "Martin Bača"
  "relation": "member of sports team"
  "tail": "Czech Republic national under-18 football team"
  "start": "2002-01-01"
  "end": "2002-01-01"
  "type": "INTERVAL"
}
```
