+
+## 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)**

+### Loading

+
+dataset = load_dataset("allegro/klej-dyk")
+pprint(dataset['train'][100])
+
+#{'answer': '"W wyborach prezydenckich w 2004 roku, Moroz przekazał swoje '

+```
+
+### 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}
