+## Counting translation instances
+In order to count translation instances containing English paired with German, French, Spanish, Portuguese, Italian or Dutch, you can use:
+```python
+from datasets import load_dataset
+import json
+from tqdm import tqdm
+
+# Specify the dataset name
+dataset_name = "RaiBP/openwebtext2-first-30-chunks-lang-detect-raw-output"
+
+# Load the dataset
+translation_dataset = load_dataset(dataset_name, data_dir="translation")
+
+dataset = translation_dataset["train"]
+n_examples = len(dataset)
+total_instances = 0
+counts_dict = {"de": 0, "fr": 0, "es": 0, "pt": 0, "it": 0, "nl": 0}
+others_count = 0
+instances = {}
+for document in tqdm(dataset, total=n_examples):
+    embedded_label = document["embedded_label"]
+    primary_label = document["primary_label"]
+    document_id = document["document_index"]
+    instance_id = document["instance_index"]
+    id = f"{document_id}-{instance_id}"
+    if id not in instances.keys():
+        instances[id] = [f"{embedded_label}-{primary_label}"]
+    else:
+        instances[id].append(f"{embedded_label}-{primary_label}")
+
+for id, labels in instances.items():
+    state = 0
+    found_langs = []
+    for langs in labels:
+        lang_pair = langs.split("-")
+        if "en" in lang_pair:
+            non_english = lang_pair[0] if lang_pair[1] == "en" else lang_pair[1]
+            if non_english in counts_dict.keys():
+                state = 1  # found a translation with English and a language in the counts_dict
+                found_langs.append(non_english)
+            elif state != 1:
+                state = 2  # found a translation with English and a language not in the counts_dict
+        elif state != 1:
+            state = 2  # found a translation without English
+    if state == 1:
+        majority_lang = max(set(found_langs), key=found_langs.count)
+        counts_dict[majority_lang] += 1
+    elif state == 2:
+        others_count += 1
+    else:
+        print("Error: state is 0")
+
+# Specify the file path where you want to save the JSON file
+file_path = "translation_counts.json"
+counts_dict["others"] = others_count
+
+# Save the dictionary as a JSON file
+with open(file_path, "w") as json_file:
+    json.dump(
+        counts_dict, json_file, indent=2
+    )  # indent argument is optional, but it makes the file more human-readable
+```
