Data. Messages from 248 Supermom community groups on WhatsApp in Indonesia, gathered from 1 January to 24 September 2026. After removing duplicates and exact repeat posts, 11,291 unique messages remain.
Milk type. Each message is tagged from its own text. Formula covers "sufor", "susu formula", high-calorie and specialist milks, and formula brands. Liquid milk covers UHT, fresh, pasteurised, full cream, and boxed milk, and liquid milk brands. Messages that mention milk without saying which type are excluded from the formula versus liquid milk comparison.
Sentiment. Scored per message with a lexicon built for Indonesian parenting slang, covering refusal, stool changes, allergy signs, price, sugar, weight, relief, enjoyment, and suitability, with negation handling. Positive words inside questions are ignored, while described symptoms still count. A hand check of random messages agreed with a human reading roughly 7 times in 10, so treat scores as directional.
Themes. Twelve themes are tagged by keyword. A message can carry several themes. Theme shares use formula and liquid milk messages, including those naming both.
Limits. Sentiment is scored for the whole message, not for each milk type within it, so comparison messages count towards both. Sarcasm and emoji are read literally. Health signals are self-reported and are described directionally only.
Privacy. No individual messages are published on this page. The examples shown are short English paraphrases with names, contacts, and brand names removed. Group names and member details are never shared.
