+## Description
+
+Polish CDSCorpus consists of 10K Polish sentence pairs which are human-annotated for semantic relatedness (**CDSC-R**) and entailment (**CDSC-E**). The dataset may be used to evaluate compositional distributional semantics models of Polish. The dataset was presented at ACL 2017. 
+
+Although the SICK corpus inspires the main design of the dataset, it differs in detail. As in SICK, the sentences come from image captions, but the set of chosen images is much more diverse as they come from 46 thematic groups.
+
+
+## Tasks (input, output, and metrics)
+
+The entailment relation between two sentences is labeled with *entailment*, *contradiction*, or *neutral*. The task is to predict if the premise entails the hypothesis (entailment), negates the hypothesis (contradiction), or is unrelated (neutral).
+
+**Input**: ('sentence_A', 'sentence_B'): sentence pair
+
+**Output** ('entailment_judgment' column): one of the possible entailment relations (*entailment*, *contradiction*, *neutral*)
+
+**Domain:** image captions
+
+*Example:*
+
+- b **entails** a (a **wynika z** b) – if a situation or an event described by sentence b occurs, it is recognized that a situation or an event described by a occurs as well, i.e., a and b refer to the same event or the same situation;  
+Żaden mężczyzna nie stoi na przystanku autobusowym. (Eng. No man standing at the bus stop.) vs. Mężczyzna z żółtą i białą reklamówką w ręce stoi na przystanku obok autobusu. (Eng. A man with a yellow and white commercial in his hand stands at a bus stop next to a bus.) → **entailment**
+
+**Measurements**: Accuracy

The procedure generally builds on steps designed to assemble the SICK corpus, which contains pairs of English sentences annotated for semantic relatedness and entailment, because we aim at building a comparable dataset. However, the implementation of particular building steps significantly differs from the original SICK design assumptions, which is caused by both lack of necessary extraneous resources for an investigated language and the need for language-specific transformation rules. The designed procedure is verified on Polish, a fusional language with a relatively free word order, and contributes to building a Polish evaluation dataset. The resource consists of 10K sentence pairs which are human-annotated for semantic relatedness and entailment. The dataset may be used for the evaluation of compositional distributional semantics models of Polish.",

+## Examples
+
+### Loading
+
+```python
+from pprint import pprint
+
+from datasets import load_dataset
+
+dataset = load_dataset("allegro/klej-cdsc-e")
+pprint(dataset["train"][0])
+
+# {'entailment_judgment': 'NEUTRAL',
+#  'pair_ID': 1,
+#  'sentence_A': 'Chłopiec w czerwonych trampkach skacze wysoko do góry '
+#                'nieopodal fontanny .',
+#  'sentence_B': 'Chłopiec w bluzce w paski podskakuje wysoko obok brązowej '
+#                'fontanny .'}
+```
+
+### Evaluation
+
+```python
+import random
+from pprint import pprint
+
+from datasets import load_dataset, load_metric
+
+dataset = load_dataset("allegro/klej-cdsc-e")
+dataset = dataset.class_encode_column("entailment_judgment")
+references = dataset["test"]["entailment_judgment"]
+
+# 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': 0.325}
+# {'f1': 0.2736171695141161}
