+# Paraphrases of Sentences from Tatoeba
+
+Downloaded: 2024-07-08
+
+**Description:**
+- Large multilingual paraphrase dataset
+- If two sentences translate to the same sentence in a foreign language, then those two sentences could be paraphrases.
+
+**Creation Process:**
+1. Translation pairs of sentences are first linked in a large undirected graph.
+2. The connected components of the graph contain sentences with similar meanings.
+3. Sentences in the same language in the same component are taken to be paraphrases.
+4. Only clusters of 2-20 sentences are counted. Any larger cluster is likely to come from irrelevant sentences linked by bad translation.
+5. Only languages with at least 10 clusters are included here.
+
+**Format:**
+- GZipped JSON files
+- Each line contains one cluster of paraphrase sentences in JSON format
+
+**Dataset Configs:**
+- [ISO 639-3 language codes](https://en.wikipedia.org/wiki/List_of_ISO_639-3_codes) as listed on Tatoeba
+
+**Sample entry:**
+
+```json
+{
+  "id": 5,
+  "sentences": [
+    "Today is June 18th and it is Muiriel's birthday!",
+    "It's 18th June today, and also Muiriel's birthday!",
+    "Today is June 18th, the birthday of Muiriel!",
+    "Today is June 18 and it is Muriel's birthday!"
+  ]
+}
+```
+
+`id`: The cluster ID of the sentences. Clusters with the same ID in other languages mutually translate to this set of sentences.
+
+`sentences`: List of sentences belonging to this cluster. That is, those sentences are paraphrases of each other.
+
+# Limitations
+
+Many important things are lost in translation. Even if two sentences translate to the same thing in a foreign language, they might not be good paraphrases.
+
+- Context and connotations ("What's up, Mike?", "What's wrong, Mike?")
+- Gendered common nouns ("I need to get rid of it.", "I need to get rid of her.", "I need to get rid of him.")
+- Ambiguous cases that could be the same or different.
+  - "I'll shoot it down.", "I'll kill it with a gun."
+  - "What kind of people do you prefer?", "What's your type?", "What kind of guys do you like?"
+
+Also some languages have important features such as:
+
+- [Familiar vs. formal forms](https://en.wikipedia.org/wiki/T%E2%80%93V_distinction)
+- Verb tenses, modality, and moods (so a sentence pair can be paraphrases in one language but not in others)
+- Vocabulary, noun distinctions, and cultural concepts (so foreign translations will lose the original meaning of the sentence)
+- Idioms, dialects, slang, jargon
