🏆 BERTopic v18 - "The Pure"
Hypothesis
Entity fusions created artificial high-frequency tokens that dominated n-grams, causing redundancy.
Changes from v17:
- REMOVED all entity fusions (text is now natural)
- RESTORED ngram_range=(1, 4) to capture full phrases
- PartOfSpeech + MMR(0.8) representation chain
- top_n_words=7
Expected Result:
Keywords like "tribunal ambiental antofagasta" instead of "tribunalambiental antofagasta"
