# klej-dyk

## Description

The Czy wiesz? (eng. Did you know?) the dataset consists of almost 5k question-answer pairs obtained from Czy wiesz... section of Polish Wikipedia. Each question is written by a Wikipedia collaborator and is answered with a link to a relevant Wikipedia article. In huggingface version of this dataset, they chose the negatives which have the largest token overlap with a question.

## Tasks (input, output, and metrics)

The task is to predict if the answer to the given question is correct or not. 

**Input** ('question sentence', 'answer' columns): question and answer sentences

**Output** ('target' column): 1 if the answer is correct, 0 otherwise. Note that the test split doesn't have target values so -1 is used instead

**Domain**: Wikipedia

**Measurements**: F1-Score

**Example**: 
*Czym zajmowali się świątnicy? vs. Świątnik – osoba, która dawniej zajmowała się
obsługą kościoła (świątyni).* → **1 (the answer is correct)**

## Examples

### Loading

```python
from pprint import pprint

from datasets import load_dataset

dataset = load_dataset("allegro/klej-dyk")
pprint(dataset['train'][100])

#{'answer': '"W wyborach prezydenckich w 2004 roku, Moroz przekazał swoje '
#           'poparcie Wiktorowi Juszczence. Po wyborach w 2006 socjaliści '
#           'początkowo tworzyli ""pomarańczową koalicję"" z Naszą Ukrainą i '
#           'Blokiem Julii Tymoszenko."',
# 'q_id': 'czywiesz4362',
# 'question': 'ile partii tworzy powołaną przez Wiktora Juszczenkę koalicję '
#             'Blok Nasza Ukraina?',
# 'target': 0}
```

### Evaluation

```python
import random
from pprint import pprint

from datasets import load_dataset, load_metric

dataset = load_dataset("allegro/klej-dyk")
dataset = dataset.class_encode_column("target")
references = dataset["test"]["target"]

# generate random predictions
predictions = [random.randrange(max(references) + 1) for _ in range(len(references))]

acc = load_metric("accuracy")
f1 = load_metric("f1")

acc_score = acc.compute(predictions=predictions, references=references)
f1_score = f1.compute(predictions=predictions, references=references, average="macro")

pprint(acc_score)
pprint(f1_score)

# {'accuracy': 0.5286686103012633}
# {'f1': 0.46700507614213194}
